Scheduling and Publishing

Use these patterns to reduce last-minute publish failures and keep cross-channel campaigns predictable.

Choose the right scheduling mode

• Use fixed-time scheduling when a launch, embargo, or partner handoff must happen at a precise time.
• Use queue scheduling when consistency matters more than a specific minute.
• Use drafts when copy or media still needs review before a post is allowed into the publishing pipeline.

Add music to TikTok image posts

• Upload your image set, pick TikTok tab, and toggle Use TikTok music.
• Choose from the cleared music list; personal libraries are not available via API.
• Music is trimmed to the image carousel length; preview before scheduling.

Link YouTube Shorts to long-form videos

• In the YouTube tab, add a CTA link to the long-form video in the description and pin the comment after publishing.
• Keep Shorts under 60 seconds and set the Short checkbox so YouTube handles correct aspect ratio.

Threads and X limitations

• Threads and X/Twitter limit how long a thread can be and how many media items can appear. Respect the platform limits shown in the composer.
• For Instagram Threads, API currently restricts scheduling; publish from the mobile app if you hit an error.

Platform duplicate-content guard

• SyncPostly blocks identical captions to multiple accounts on the same platform to prevent spam flags. Vary wording or timing between accounts.
• Cross-platform reuse is allowed; we still recommend per-platform tweaks for performance.

Before you schedule a campaign

• Confirm the workspace time zone matches the team that owns the calendar.
• Check quiet hours if posts seem to be landing later than expected.
• Make sure all required media has finished processing before setting the final publish time.
• For multi-account campaigns, spot-check platform tabs instead of assuming the base caption is safe everywhere.

Posting videos to Bluesky

• Upload MP4 under 100 MB and shorter than 2 minutes.
• Provide alt text; Bluesky enforces accessibility.

Custom thumbnails

• YouTube: upload a thumbnail image in the Thumbnail field; 1280x720 recommended. Shorts still support thumbnails via API.
• TikTok: choose a frame after upload; API does not allow custom thumbnails for some account types.

Save TikTok posts as drafts

• Toggle Save as Draft in the TikTok tab to push the post into the TikTok Drafts folder instead of publishing immediately.
• Drafts still consume upload quota on TikTok; schedule wisely.

Carousel posts

• Up to 10 images for Instagram; we allow more in the uploader, but only the first 10 are sent to comply with API rules.
• Drag to reorder; aspect ratios must match the platform's accepted ranges.
