Overview

Instagram requires a Business or Creator account (not personal) and connects through Facebook.
You can easily switch your account to a Business or Creator account by following the instructions here.

Connecting Instagram

Post Preview

As you draft your post, the editor shows a live preview that matches how your content will appear on Instagram. For planning your profile aesthetic, switch to Grid Preview to see how your new post will fit into your existing Instagram grid. This helps you maintain a consistent visual style across your profile.

Photo Options

Photo tagging: Tag users directly on your images to increase engagement and notify them:
  1. Add images to your post
  2. Open the Tags option
  3. Click anywhere on the image where you want the tag to appear
  4. Enter the Instagram handle
Photo tagging is only available for images in Feed posts. Videos in Feed posts and all Reels content use text-based tagging instead.

Instagram-Specific Features

Location: Add a location to Feed posts to increase discoverability. Search for any place and it will appear on your published post. Collaborators: Invite up to 3 other Instagram accounts to co-author your post. When published, collaborators receive a DM to accept the invitation, and the post appears on both profiles. Cover Photo (Reels only): Upload a custom thumbnail for your Reel. Share to Feed (Reels only): Control whether your Reel appears in both your profile grid and the Reels tab, or just in Reels.

Auto-Engagements

Instagram Auto Eng Schedule a first comment to publish automatically after your post goes live. This is the only auto-engagement type available for Instagram due to API limitations. The comment must be posted from the same account that the post is scheduled for.
TypeWhat it does
First CommentAdd a comment immediately after posting (great for hashtags or CTAs)
Many creators put their hashtags in the first comment to keep captions cleaner. It doesn’t affect discoverability.
