Key Features

One upload, hundreds of scheduled posts

Build an entire cross-platform campaign in a spreadsheet, validate every row, and schedule it in one batch.

  • CSV UploadSchedule 500 posts from one CSV file, from the dashboard or the API.
  • Pre-Upload ValidationEvery row is checked before scheduling. Use dry-run mode to get a full validation report without creating a single post.
  • Per-Platform ColumnsSet Instagram first comments, TikTok privacy, YouTube titles, Pinterest boards, and more with platform-specific columns.
  • Timezone Per PostGive each row its own tz value, or use offset ISO timestamps, to hit the right local time everywhere.
  • Queue & Draft ModesSend rows to your posting queue with use_queue, save them as drafts, or publish immediately with publish_now.
  • Media From URLsAttach images and videos with media_urls. PostZen downloads and validates each asset per platform.

Frequently asked questions

Still have questions?

How many posts can I bulk schedule at once?

Up to 500 posts per CSV upload. There is no limit on how many files you upload, so larger campaigns can be split across multiple batches.

What columns does the CSV need?

Four required columns: post_content, platforms, profiles, and schedule_time. Optional columns cover timezones (tz), media (media_urls), queue and draft modes, and platform-specific settings like instagram_first_comment or tiktok_privacy.

What happens if some rows have errors?

Every row is validated independently and you get a per-row report. Use dryRun=true to validate a file without scheduling anything, then fix errors and re-upload.

Can I customize posts per platform in one row?

Yes. Platform-specific columns let you set YouTube titles, Instagram first comments and collaborators, TikTok privacy and duet settings, Pinterest boards, and Telegram formatting in the same row.

Where can my media files be hosted?

Any publicly accessible URL — S3, Cloudflare R2, a CDN, or your own server. PostZen downloads, validates, and processes each file per platform.

Can I bulk schedule into my posting queue?

Yes. Set the use_queue column and those rows fill the next available queue slots instead of needing exact times.

Is bulk scheduling available on the free plan?

Yes. Every plan includes CSV upload and the bulk API. The free tier covers your first 2 social accounts with unlimited posts.
