Important: This guide shows what’s available in posterly today. Limits and availability depend on the account connection and post format. Pinterest multi-image Pins support 2 to 5 images, and X supports up to 4 images per post. On article platforms, extra images appear in the article body. “Custom cover” means an uploaded or attached cover image; TikTok supports selecting a video frame or slideshow photo instead.

How to read this section: “Extra tagging tools” covers media tags, company mentions, resolved profile mentions, product tags, topic tags, and article tags. It does not measure ordinary @mentions typed in the post text. On X, type the correct @username in the composer and it becomes a profile link when published. “Audience controls” includes reply settings, quote controls, and interaction controls. Instagram polls require a Meta connection and a feed photo, Reel, or carousel; interactive Story poll stickers are not supported. Mastodon poll limits depend on the connected instance.
