How Reply in DM Works

Connect your account, set your rules, and let Reply in DM handle the rest. Here's a detailed look at every step.

1

Connect Your Instagram or Facebook

It takes 30 seconds. Sign in with your Instagram or Facebook account through a secure OAuth login—the same flow used by every major social media tool.

  • We never post anything on your behalf
  • We only listen for new comments on your posts
  • Disconnect at any time from your account settings

Create a Post or Pick an Existing One

Create and schedule a brand new post directly from Reply in DM, complete with media and captions. Or, if you already have a post live on your page, simply select it and set up your auto-reply rules on top of it—Reply in DM will automatically send DMs to everyone who already commented, then keep watching for new comments going forward.

  • Compose new posts with media and captions
  • Schedule posts for the perfect time
  • Or pick any existing post from your feed
  • Retroactively DMs everyone who already commented

Set Your Reply Rules

Choose how comments trigger a DM. Reply in DM supports two rule types:

Catch-All

Every single comment triggers a DM—perfect when you want everyone to get your link, offer, or resource.

Keyword

Only comments containing specific words (like "LINK", "YES", or "DEAL") trigger a DM. Great for targeted engagement.

What can you include in the auto-reply? A text message, clickable links, attached files (PDFs, images), and discount codes. Mix and match to give each commenter exactly what they need.
