Changelog

Agents can finally see learned voice

Until now, the MCP get_brand_profile tool only returned the manually entered brand voice (tone, audience, values). The voice posterly learns automatically from your account's real published captions — the "Learned from your posts" panel on the dashboard — was invisible to MCP agents. So when you asked an agent "do my accounts have any learned captions?", it correctly answered "no" even though the dashboard showed them.

That gap is now closed.

What changed

• get_brand_profile now includes a learned_voice array — one entry per connected account that has a derived voice, with its narrative summary, voice traits, style guidelines, and observed posting habits (typical length, emoji/hashtag rates, question hooks, line breaks).
• get_learned_voice is a new tool keyed by social account ID (from list_accounts or list_brand_accounts). Use it to read one account's learned voice directly.
• New API endpoint: GET /api/v1/accounts/{id}/learned-voice.

Learned voice is read-only through the API and MCP — exactly like the dashboard, it never overwrites your saved brand profile. posterly derives it automatically once an account has enough published posts.

If you can do it in the composer, you can now do it from code or an agent.

What's new

All the platform settings added across recent releases are now part of the public API and the MCP server (posterly-mcp-server@0.22.0). Pass them in the settings object when calling create_post or update_post.

Threads

• settings.poll - add a native Threads poll with a question and up to 4 options
• settings.topic_tag - set a topic tag on the post (e.g. "Technology")

Telegram

• settings.poll - send a native Telegram poll, including quiz mode and anonymous options
• settings.buttons - attach inline keyboard buttons with URLs

Bluesky

• settings.content_label - apply a content warning label (e.g. "nsfw", "graphic-media")
• settings.tags - attach hashtag tags separate from the post body
• settings.quote_url - quote-post another Bluesky URL
• settings.disable_quotes - prevent others from quoting the post

YouTube

• settings.notify_subscribers - control whether subscribers get notified on publish (default: true)
• settings.add_shorts_hashtag - automatically append #Shorts for vertical video uploads

X and Threads reply controls (widened)

• settings.reply_settings now accepts "everyone", "following", "mentioned", and "subscribers" on both platforms

Cross-platform AI content flag

• settings.ai_generated - set to true to apply the platform's native AI-content label on TikTok, X, YouTube, and Pinterest in a single field

Good to know

• Discovery: call GET /platforms on the REST API or the list_platforms MCP tool. Both return the full per-platform settings schema with field names, types, accepted values, and examples. No guessing required.
• MCP server: update to posterly-mcp-server@0.22.0 to get the new settings. The server works with any MCP client, including Claude, ChatGPT, Cursor, Windsurf, Cline, and more.
• Backwards compatible: all new settings fields are optional. Existing integrations continue to work without any changes.
• Same validation: the API applies the same rules as the composer. If a field conflicts with the post type or platform limits, the API returns a clear error before the post is queued.

A pile of polish that adds up. This release covers accessibility, transparency, and finer control across seven platforms, all from the same composer you already use.

What's new

Alt text everywhere

• Facebook, LinkedIn, and Pinterest now publish image alt text alongside your post. Instagram, X, Threads, and Bluesky already did this. Now every major image platform posterly supports includes your alt text when it goes out. Better accessibility, better image SEO, no extra steps.

AI-content labels

• TikTok, X, YouTube, and Pinterest each have a native "Created with AI" label you can apply per post. Turn on the toggle in the platform tab and the label goes out with the post, using each platform's own official mechanism. Useful for compliance and transparency, and increasingly required by platform policy.

More reply controls

• X gains two new reply audiences: "Subscribers only" and "Verified accounts only", on top of the existing Everyone, Followers, and Mentioned options.
• Threads gains "Followers only" and "Only you" reply settings, in addition to Everyone and Mentioned.

Telegram inline buttons

• Add up to 3 CTA buttons under a Telegram post, for example "Read more", "Shop now", or "Watch the video". Each button takes a label and a URL. Great for driving traffic from Telegram channels without cluttering the post body.

YouTube improvements

• A Notify subscribers toggle lets you control whether YouTube sends a notification to your subscribers when the video goes live. Useful for batching uploads without flooding notifications.
• Vertical clips (9:16 ratio under 60 seconds) now get #Shorts appended to the description automatically, so they qualify for the Shorts feed without any manual tagging.

Google Business Profile

• CTA buttons are now available on standard GBP posts. Add a button type (Book, Order, Shop, Learn more, Sign up, Call) and a URL to drive action from your Business Profile.
• Video posts are now supported on GBP. Upload a video, add your caption, and publish directly to your Business Profile.

Good to know

• Alt text you write in the composer is stored once and sent to every platform that supports it. If a platform does not support alt text, the field is ignored rather than causing an error.
• AI-content labels are per platform, so you can label a TikTok version of a post without labeling the Pinterest version.
• Telegram inline buttons require a public channel or group; they do not work in private one-to-one chats via the bot.
• YouTube's Notify subscribers toggle only affects the notification, not the visibility of the video. Subscribers can still find it without a notification.
• #Shorts auto-tagging only fires when both conditions are met: 9:16 aspect ratio and duration under 60 seconds. It appends to your description, so any text you already wrote is preserved.
• GBP video posts are processed asynchronously by Google. The post may take a few minutes to appear after publishing.

Everything Bluesky power users have been asking for is now in the composer.

What's new

• Quote posts. Paste any Bluesky post URL in the Bluesky tab to attach it as a quote. Your own text and media go above it, the quoted post shows below, just like it does on Bluesky itself.
• Content warnings. Self-label a post before it goes out. Choose from Sexually suggestive, Nudity, Adult content, or Graphic media. Viewers with the matching Bluesky setting will see the post behind a tap-to-reveal.
• Hidden discovery tags. Add up to 8 tags that improve how your post ranks in Bluesky feeds and search, without cluttering the visible caption. Think of them as SEO for your Bluesky posts.
• Disable quote posts. Turn off the ability for others to quote a specific post. Useful for announcements or anything you want shared as-is, not riffed on.

These join the Bluesky controls already in posterly: video, @mentions, hashtags, and automatic link cards.

Good to know

• Quote post and original content can coexist. You can include text, images, or video alongside a quote.
• Content warning labels are set per-post and match the exact label categories Bluesky supports. The viewer's own settings determine whether the warning is shown.
• Hidden tags count toward Bluesky's tag limit. If you also use hashtags in your caption, the total across both cannot exceed 8.
• Disabling quotes applies going forward. It does not remove quote posts that already exist.

posterly now has an affiliate program. Share posterly with your audience and earn 30% recurring commission on every subscription you refer.

What's new

• Earn 30% recurring. Get paid every month a referral stays subscribed, on all four plans.
• Your own dashboard. Open Affiliates in the sidebar to grab your referral link and QR code and track clicks, leads, sales, and earnings in real time.
• Free to join. No cost and no minimums. Anyone can become an affiliate, whether or not they use posterly.

How it works

1. Open Affiliates in your dashboard, or visit the affiliate page.
2. Share your unique link.
3. When someone subscribes within 30 days of clicking, the sale is credited to you automatically.

Good to know

• Commission applies to paid subscriptions only, not one-time credit packs or add-ons.
• Referrals are tracked with a 30 day cookie and attributed automatically through Stripe.

Your links finally look like links.

When you include a URL in a Bluesky or LinkedIn post (with no other media attached), posterly now fetches the page's Open Graph data and builds a native preview card, with the title, description, and thumbnail image, before the post goes out.

What's new

• Bluesky link cards. Bluesky does not scrape link metadata on its own. posterly fetches the Open Graph data server-side and attaches a proper card to the post, so your link renders with a title, description, and preview image instead of plain text.
• LinkedIn article previews. Same story on LinkedIn. posterly builds the native article-style link preview, including the thumbnail image, so the post looks polished in the feed.
• Fully automatic. No toggle, no extra step. Just include a URL in the caption and leave the media uploader empty. posterly detects the link and fetches the preview in the background before publish.

Good to know

• The preview is generated from the page's Open Graph tags (og:title, og:description, og:image). Pages without OG tags will fall back to whatever metadata is available.
• If you attach an image or video to the post, the media takes precedence and no link card is generated. This matches how both platforms handle mixed content natively.
• The fetch happens server-side via a safe outbound request at publish time, so there is nothing to configure and no third-party service involved.

You can now tell posterly which English to write in, per brand.

What's new

• Language setting on each brand. In Brands, open a brand profile and pick British English, American English, or Auto (match my posts) under Brand voice.
• Applies everywhere AI writes. The choice flows into AI captions, proactive suggestions, and the AI Agent, so spelling and idiom stay consistent (colour, organise, whilst vs color, organize, while).
• Auto by default. Auto follows the voice already in your posts, so nothing changes unless you set a specific variant.

Last update brought Google Business profile photo and video management to the dashboard. Now it is on the public surface too, so your agents and integrations can do it without a person clicking around.

What's new

• List media over the API and MCP: GET /api/v1/google-business/media and the list_google_business_media tool return every photo and video on a location's profile gallery.
• Add media: POST /api/v1/google-business/media (or the add_google_business_media tool) attaches a photo or video to a category from a public URL. Upload the file first with the existing /media endpoints to get that URL.
• Remove media: DELETE /api/v1/google-business/media (or delete_google_business_media) removes an item by its resource name.

Good to know

• Listing requires the accounts:read scope; adding and removing require posts:write plus publisher access to the workspace.
• Write tools confirm before acting, the same as the review-reply tools.
• This manages the standing profile gallery, separate from media attached to a post. Photos are capped at 25MB; videos at ~30 seconds and 75MB and pass Google's review before appearing.
• Available in posterly-mcp-server@0.23.0.

Your Google Business Profile media is one of the first things customers see, and now you can manage it right inside posterly.

What's new

• Photos & Videos tab. Open the Google Business page and switch to the new Photos & Videos tab to see every photo and video on a location's profile, grouped by type.
• Add by category. Upload a cover photo, logo, interior shot, product photo, video, and more. posterly sends it straight to Google.
• Remove media. Clear out anything outdated or off-brand in a couple of clicks.
• Multi-location. Manage media for each of your connected Google Business locations from one place.

Good to know

• This manages the standing gallery on your profile, which is separate from the photo you attach to a Google Business post.
• Cover and profile photos are single-slot: adding a new one replaces the current photo for that slot.
• Photos must be under 25MB. Videos must be under 75MB and go through Google's review before they appear. Removing media is permanent, so keep a copy of anything you might want back.
• No new Google permission is needed. This uses the access posterly already has for your Business Profile.

Polls are now live on X, LinkedIn, Threads, and Telegram, all schedulable from the composer.

What's new

• Polls on Threads. Open the Threads tab in the composer, turn on Poll, write your question, and add 2 to 4 options. Threads polls are text only and run for a fixed 24 hours (that's Threads' rule, not ours).
• Polls on Telegram. Open the Telegram tab, turn on Poll, write a question, and add 2 to 10 options. You can optionally allow multiple answers. Posts as a native Telegram poll to your channel or group.
• Scheduled like any other post. Set it for later or publish now. Polls go out through each platform's official API.

Good to know

• Threads polls are text only and cannot include images or video. The composer will flag this if you add media.
• Threads polls always run for exactly 24 hours. There is no option to change the duration.
• Telegram polls support 2 to 10 options and can be set to allow multiple answers per voter.
• Polls cannot be edited once they are live, so check your question and options before publishing.

Building on our API? Threads and Telegram polls are available through the public API and MCP too: pass settings.poll with a question and options (and optionally allows_multiple_answers for Telegram) when you create a post.

Most people set their brand voice once and never touch it again. So posterly now keeps it current for you.

What's new

• Voice learned from real posts. posterly studies each account's published captions and learns how you write: length, emoji and hashtag habits, rhythm, openers, recurring phrases, and topics.
• Captions just get better. The learned voice is blended into AI caption generation automatically, in the composer, the AI Agent, campaigns, and the API. Nothing to configure.
• Per account. Your buttoned-up LinkedIn voice and your casual X voice are learned separately.
• See what it learned. Open a brand profile in Brands and check the "Learned from your posts" panel for a plain-English summary and the habits behind it.

Good to know

• It never changes your saved brand voice on its own. If you want the learned voice in your saved profile, click "Apply to brand voice", review the change, and save.
• An account needs about 10 published posts before posterly can learn its voice. It refreshes automatically as you keep posting.
• Available on Pro and up.

Building on brand voice learning, posterly now turns what it has learned into ready-to-use drafts.

What's new

• Suggestions on your dashboard. A new card surfaces a few posts drafted in your account's voice, ready to copy, edit, or dismiss.
• Suggestions in the composer. While writing, open the suggestions button in the caption toolbar to drop a draft straight into your post for the selected platform.
• A weekly nudge. If you have gone quiet, posterly emails you that week's suggestions so you never stare at a blank composer.

Good to know

• Suggestions are drafted from your own recent posts, in that account's voice. Nothing is scheduled until you say so.
• An account needs about 10 published posts before posterly can suggest in its voice. Until then the dashboard shows your progress.
• Available on Pro and up.

You can now schedule native LinkedIn polls in posterly, the same way you already could on X.

What's new

• Polls on LinkedIn. Open the LinkedIn tab in the composer, turn on Poll, write your question, add 2 to 4 options, and pick how long it runs: 1 day, 3 days, 1 week, or 2 weeks.
• Works for profiles and Pages. Post a poll from a personal profile or a company Page, whichever account you are publishing as.
• Scheduled like any other post. Set it for later or publish now. Polls go out through LinkedIn's official API.

Good to know

• A poll is text only, so it cannot include an image, video, or document. The composer flags this if you try to add media.
• LinkedIn polls are single-select, and questions cannot ask for political opinions, health status, or other sensitive data (LinkedIn's rule, not ours).
• Polls cannot be edited once they are live, so double-check the question and options before publishing.

Building on our API? LinkedIn polls are available through the public API and MCP too: pass settings.poll with a question, options, and duration when you create a LinkedIn post.

Bluesky support just grew up:

• Video posts. Schedule one MP4 per post, up to 3 minutes and 100 MB. posterly transcodes oversized or incompatible videos automatically, the same way it does for Reels and TikTok.
• Real mentions and hashtags. @handle.bsky.social now links to the profile and #hashtags are tappable and searchable. Previously these published as plain text.
• Sharper images. Large images are compressed to Bluesky's size limit automatically instead of being dropped, and every image now carries aspect-ratio hints so feeds render without layout jumps.

Also in this release: Telegram captions handle special characters correctly, caption limits match Telegram's real rules, and oversized media gets a clear error before publish instead of a cryptic one after.

Posting consistently is the whole game. Now it is one.

The hardest part of growing on social is showing up week after week. The new leaderboard turns that into a friendly competition: opt in, keep publishing, and watch yourself climb against other posterly creators.

How it works

• Opt in once. Opting in both lists you on the board and unlocks it for you to see. If you would rather not take part, the board stays blurred and you appear nowhere.
• Climb by posting. The "This month" view ranks everyone by the number of posts they publish during the calendar month.
• Win credits. At the start of each month the top 3 creators from the month just ended are awarded AI credits automatically: 25 / 15 / 10 to first, second, and third.

Compete your way

You choose how you show up. Pick your real handle, or compete under a private alias like "Anonymous Lynx" so no one sees who you are. You can change it or opt out at any time, and only members can see the board.

Find it

A trophy in the sidebar, and a rank card on your dashboard that shows where you stand this month. Open the leaderboard to opt in.

Stickers the Stories API can't publish

Instagram and Facebook keep interactive Story stickers (polls, link stickers, mentions, location) inside the native app, out of reach of any scheduler's API. That is exactly why Manual Story reminds you to post Stories by hand instead of auto-publishing them.

Now that reminder does more. When you schedule a Manual Story, you can plan the stickers up front, and posterly hands them back as a checklist the moment it is time to post.

What you can add to the brief

In the composer, toggle on Manual story, I'll post it myself, and a short Story brief appears:

• Link sticker: the URL plus an optional label like "Shop now"
• Poll: your question and its two options
• Location: the place to search for
• Notes to self: anything else you want to remember

Everything is optional, fill in only what you need. Tagging accounts works the way it always has, through the @ button in the caption toolbar, and for Manual Stories those tags now ride along in the reminder so you can add them by hand.

It arrives ready to recreate

Five minutes before the scheduled time, your reminder email now lays the whole brief out as a checklist: your poll question and options, the link and its label, the handles to mention, the location, and your notes, right next to the media and the account. Open the app, recreate it in seconds, and tap Mark as posted.

This works for single Stories and Story Series on both Instagram and Facebook. Already using Manual Story? The brief just appears under the toggle, nothing else changes.

Try it from the composer.

No more surprise yearly disconnects

TikTok, LinkedIn, and Pinterest require you to re-authorize roughly once a year for security. Until now, that limit was invisible: a connection could publish fine for months and then silently stop at the one-year mark, with a failed post as the first sign anything was wrong.

posterly now tracks that deadline and gives you plenty of warning.

What changed

• Reconnect soon badge: affected accounts on the Accounts page show an amber Reconnect soon badge starting about 30 days before the limit, with a countdown of days left.
• Email reminder: you get a heads-up email so you can reconnect even if you are not in the dashboard that week.
• Honest messaging: unlike a normal token refresh, posting does not extend this limit, so the warnings make clear that a one-time reconnect is what resets it for another year.

A single reconnect takes a few seconds and resets the clock, so your scheduled posts never lapse.

Support, right where you work

You can now ask posterly Support AI for help from inside the dashboard. It is in beta, but it already gives you a faster first answer for common questions, failed posts, reconnecting accounts, billing questions, and anything covered in the posterly docs.

Open Support, or use the support button in the bottom-right corner of the dashboard.

What it can help with

• Docs-backed answers: answers include the closest posterly docs so you can open the source and follow the full steps.
• Post checks: ask about a specific post number and posterly Support AI can look at read-only diagnostics for that post in your current workspace.
• Account health: it can spot common connected-account issues, including expired tokens, reconnect signals, and recent publishing errors.
• Conversation history: your recent support conversations stay visible on the Support page, so you can pick up where you left off.

Human handoff when it is needed

Human support is still there for account-specific cases, billing issues, and anything the AI is not confident about. If you are on Pro, Power User, or Agency, you can open a ticket after the AI has answered if the answer did not solve it.

Starter users can use posterly Support AI and the docs, but direct human support is included on Pro and above.

For API and MCP users

Posterly Support AI is also available through the authenticated API and MCP tools. Agents can ask support questions with the same docs-backed answers and read-only account/post diagnostics, as long as the caller has the right posterly API scopes.

Try it from Support.

TikTok now auto-publishes

posterly is approved for TikTok Direct Post, so scheduled TikToks publish directly to your profile at the time you choose. The "open the TikTok app and tap Post" step is no longer required for every video.

Two ways to post

• Auto-publish (default): posterly posts the video to your TikTok profile automatically. Pick an audience and interaction settings in the composer, schedule it, and you are done.
• Finish in TikTok app: prefer to add a trending sound, effect, or final edit in TikTok? Switch the post to this mode and posterly sends it to your TikTok inbox so you can finish and post it yourself.

Set a default per account

On the Connect page, each TikTok account has a default mode. Set it to Auto-publish or Finish in app once, and new posts start there. You can still change any individual post in the composer.

What to expect

Auto-publish requires you to choose an audience on every post, which is a TikTok rule. posterly loads the available audiences directly from your account, and after upload TikTok may take a few minutes to process the video before it appears.

Try it from the composer by selecting a TikTok account.

A preview frame for every video

When you upload a video to the composer, posterly now grabs a still frame from it automatically and keeps that frame as the post's thumbnail. Your video tiles show a real preview instead of a grey placeholder, and they keep it even after the post has gone live.

What changed

• Posters are captured on upload: drop in a TikTok video, a reel, or any other clip and posterly saves a small preview image right away. Nothing to click.
• Tiles stay populated after publishing: once a post publishes, the original upload is cleaned up to save space. The lightweight poster stays behind, so the tile keeps its picture.
• Everywhere you preview posts: the poster shows up in Card view, the calendar's visual layout, and your Link in Bio recent posts.
• Your own cover wins: if you picked a custom cover or frame for a reel, that stays the thumbnail. The automatic poster only fills in when there is nothing else to show.

Why this matters

A wall of grey placeholders makes it hard to tell your posts apart at a glance. Now your videos look like your videos, before and after they publish.

Decide what lands in your inbox

You can now choose which emails posterly sends you. Open Account settings, find the new Email Notifications section, and switch any category on or off. Your choices save instantly and apply across everything we send.

What you can control

• Product updates: new features and the monthly "what's new" roundup.
• Tips and getting started: short guides to help you get more out of posterly.
• Weekly recap: your Monday summary of scheduled and published posts.
• Reminders and offers: nudges when something needs attention, plus the occasional offer.

Always on

Account and billing emails (payment issues, security, failed posts, and account notices) are never switched off. If something needs your attention to keep your posts publishing, we will always tell you.

Why this matters

Before, the only way to quiet marketing email was to unsubscribe from everything, which also silenced the important account alerts. Now you get a clean, per-category choice, and the critical mail always reaches you.

Manage your preferences anytime from Account settings.

Your schedule, easy to check from your phone

A lot of the time you just want a quick look at what is happening without opening your laptop. We gave posterly on mobile a proper pass, so the dashboard and calendar are now clean, fast, and easy to read on a small screen.

What is better

• Calendar at a glance: the month view now displays correctly on mobile, so you can see which days already have posts without anything spilling onto the card below.
• Your numbers in a tidy grid: Scheduled, Published, Connected Accounts, and anything needing Attention now sit in a simple two-by-two layout you can take in instantly.
• A cleaner dashboard: the duplicate row of shortcuts is gone on mobile, because the bottom bar already gets you to Create, Posts, Dashboard, and Connect in one tap.
• See what is next: the Up next list shows the posts going out soon, so you are never guessing.
• Feedback on the go: the feedback and ideas board is now fully usable on a phone, so you can report a bug or request a feature from anywhere.
• Smoother loading: no more flash of the desktop calendar before the mobile view settles.

What mobile is great for

• A quick check-in: see what is scheduled next and confirm everything is on track.
• Keeping an eye on your numbers: published count, connected accounts, and anything that needs attention.
• Staying on top of your calendar: spot your busy days and quiet days at a glance.
• Jumping in fast: the bottom bar takes you straight to creating a post, your posts, or your connections.

Why this matters

You should not need to be at your desk to know your social presence is on track. Open posterly on your phone and the things that matter are right there: your calendar, what is next, and how you are tracking.

Open your dashboard on your phone to see it.

Turn a few photos into one collage

The new collage maker lives in Design Studio and makes it quick to combine several photos into a single image, sized for square posts, portrait feeds, or stories and reels.

Open Design Studio, click Collage, pick a layout, and drop in your photos. Send the result straight to the composer or keep editing it on the canvas.

What is included

• Simple layouts: 4 equal quadrants, side by side, stacked, 1 + 2, 1 + 3, three strips, and six-photo grids.
• Made for every placement: square (1:1), portrait (4:5), and story / reel (9:16) formats.
• Add photos fast: upload several at once and they fill the cells in order.
• Rearrange in a tap: drag a photo onto another cell to swap, or press Cycle to rotate them all.
• Reframe each photo: drag to reposition and zoom inside any cell so nothing important is cropped.
• Style the gaps: adjust spacing and choose a background colour.

Why this matters

Collages are an easy way to share a set of photos as one post: product roundups, before-and-after shots, event recaps, or a simple four-up for a story. Now you can build one in seconds without leaving posterly.

Try it from Design Studio by clicking Collage.

Plan a batch in a spreadsheet, import it in one pass

Bulk Upload has a new Import from CSV mode. If you already plan content in a spreadsheet, you can now bring it straight into posterly instead of recreating each post by hand.

Fill in one row per post, drop the spreadsheet together with the media files it references, pick your accounts, and posterly turns the whole sheet into scheduled posts.

How to use it

1. Open Bulk Upload and switch to Import from CSV.
2. Download the CSV or Excel template.
3. Add one row per post: a caption, the media filename(s), an optional date and time, and an optional post type.
4. Drop the sheet and every media file it names into the drop zone at once.
5. Choose the accounts to post to, review the preview, and click Create posts.

What you can put in a row

• Caption used across every selected platform.
• Media by filename, including several filenames in one cell for a carousel.
• Schedule as YYYY-MM-DD HH:mm, or leave it blank to save the row as a draft.
• Post type (image, video, reel, story, carousel, story_series), auto-detected when blank.
• Per-platform captions such as caption_twitter to tailor the text for one network while the rest use the main caption.

Accounts are not a column. You select them in the UI, and each row is scheduled to every account you pick.

Checked before anything is created

Every row runs through the same validation the composer uses, so the importer will not create a post the composer would reject. Caption lengths, media counts, post-type rules, and the schedule are all checked up front. Rows that are ready show a green Ready badge, and anything that needs attention tells you exactly what to fix. Nothing is created until you confirm.

Details

• Imports up to 40 posts per upload.
• Works with CSV and Excel (.xlsx). Excel keeps the full date and time intact.
• Times resolve in the timezone of the brand you select.

See the Bulk Upload guide for the full column reference.
