Guide

Bulk Post guide

Prepare a CSV, give each destination the right copy, review platform and media validation, then publish or schedule the valid rows.

CSV rules
  • Use the official template with the first row as headers.
  • Do not rename or reorder headers.
  • You can delete columns you do not need, but keep the header row intact.
Scheduling
  • Use due_date to control when each row should publish.
  • Posts publish on the specified date and time.
  • ISO-like formats are the safest option for consistent scheduling.
Threads stands on its own

Put instagram,threads in the platforms column. Keep your shared caption in text, then add a Threads-specific version in threads_text. If the override is blank, Threads uses the shared text.

The preview validates the effective Threads copy against its 500-character limit. The same override pattern is available for every supported destination, such as instagram_text, discord_text, and ghost_text.

Review and fix before publishing
  • Postly checks character and hashtag limits for every selected platform.
  • Use the AI action on a flagged row to create shorter platform-specific copy while preserving the shared version.
  • Image URLs are checked for access and platform compatibility; supported image issues can be auto-fixed and saved to Postly Cloud.
  • Video issues are flagged with the platform requirement so you can replace the source file.

Bulk publishing supports Facebook, Instagram, Threads, X, LinkedIn, Google Business Profile, Pinterest, YouTube, TikTok, Bluesky, Telegram, Discord, WhatsApp, WordPress, Ghost, Hashnode, DEV Community, and Blogger.
