How to schedule social media posts across multiple platforms

Have a video ready, but keep uploading and scheduling it separately in each app? In HeyMark, you can upload the original once, prepare a version for each network, and schedule them together with Also schedule. This walkthrough takes you through destinations, each copy’s settings, and their times before you confirm.

Connect your brand’s accounts

Open My accounts and check that the accounts you want to publish to are connected. HeyMark supports Instagram, Facebook, TikTok, LinkedIn, YouTube, and X; the destinations you can use depend on your brand’s available connections and formats.

This walkthrough uses copies within the same brand. If HeyMark asks you to request approval for this post, use Send for Approval and wait for the reviewer’s decision. A pending request is not scheduled content yet: check the outcome in the calendar. For help organizing that step, see the content approval workflow.

Prepare the post and upload the original

In Content, create or open the post you want to start from. Choose its network and format, write the caption, and upload the original file you prepared for publication.

For example, start with your own vertical video as an Instagram Reel. Check that the video has uploaded and that the caption and Instagram settings are ready. An imported calendar post without an available file does not replace that upload.

Make a copy for each network

1. Open Duplicate in… on the post.
2. Keep the same brand selected and choose the destination network and format, such as TikTok Video.
3. Review the proposed day and choose it: selecting the day immediately creates a linked draft of the original post.
4. Repeat the preparation for other destinations you need, such as a YouTube Short.

The copy reuses compatible files already in HeyMark, so you do not need to upload the same original again in each app. Check the result in every copy: changing formats can leave out files the destination does not support.

After a duplicate is created, use View in the notice to open it. You can also find it in the calendar. Open each version and adjust that network’s settings. For example, review TikTok privacy and the YouTube title and visibility. Those changes do not require starting over or uploading an available, compatible file again.

Schedule the post and its copies together

Once the versions are ready, check the time zone displayed on the Content calendar. Then open Schedule from one of them and choose a future date and time.

The dialog shows Also schedule with linked copies that are still in planning. Check which ones are ready and selected. The confirmation button counts the open post and the copies you are including: for example, Schedule 3 posts.

Review the destinations and times before clicking it. You can confirm the group’s schedule in HeyMark without opening Instagram, TikTok, and YouTube to repeat the scheduling in each app.

For the same time, check each copy’s date

A copy that already has its own future time keeps it when scheduled with the original. One without a future time takes the time of the post you are scheduling from. Selecting the group does not overwrite every schedule. Actual publication depends on each platform’s processing; the posts are not guaranteed to go live at the same second.

Fictional example: you prepared a Reel, TikTok video, and Short for a future date at 6 p.m. in your calendar’s time zone. Before confirming all three, check that no copy still has, for example, an 8 p.m. time. If you want them scheduled for the same time, adjust that copy first.

You can also keep different times for each network and schedule them together. This lets you prepare the same content without forcing an identical time. For help choosing when to post, see how to find your TikTok posting time.

Check each destination in the calendar

After confirming, check in Content that every post is Scheduled for the date and time intended for that version. One scheduled post does not confirm that all copies were accepted: each copy is validated separately.

If HeyMark says one is missing, review that post and address the issue it reports before trying again. Check what is already scheduled before repeating the whole preparation.

If you cannot select a copy

• Checking…: wait for the check to finish so you can see whether the copy is ready.
• No format: open the copy and choose a valid destination.
• Check the files: review what that network requires and whether the files are available and compatible.
• Could not load: reopen the post and check its state before continuing.
• Same network already included: check whether you selected two copies for the same network. The group accepts one per network.

A copy that is already scheduled, published, or failed has its own state; it is not another planning draft ready to include. Review that version separately.
