Tag people and brands with confidence
Add mentions from Post Preview, keep your workflow consistent across supported platforms, and publish with confidence knowing exactly what tagging is supported.
How tagging works in Post Preview
Draft your post as usual, then open Post Preview to add mentions. For supported platforms like Instagram, enter @usernames as a comma-separated list, make sure the usernames are correct, then choose your post format. Postly applies tags based on each platform’s supported behavior.

Tip: Add mentions in Preview before publishing, and double-check usernames where platform support applies.
