HitDM

HitDM is a tool for Instagram comment-to-DM automation. You pick a post or Reel and a keyword, and when someone comments that keyword, HitDM sends them a private direct message with your tracked link and an optional message. It connects to Business or Creator Instagram accounts through Meta's official messaging API. Each trigger gets its own tracked URL, so you can see which comment keyword drove a click.

The free plan includes 1,000 DMs per month for one Instagram account and one workspace, with no credit card required to start. The Pro plan is listed at $9 per month and adds unlimited monthly DMs, up to three workspaces and three Instagram accounts, lead capture inside the chat after the first message, and priority email support. The site notes that Pro's unlimited means no monthly DM cap, not unlimited sends per hour, and that HitDM paces outbound DMs at roughly 500 to 600 per hour under Meta's messaging rules.

The product is aimed at creators, coaches and shops who want their links in the inbox of people who comment on a post instead of relying on a bio link. Story reply automations are listed as coming soon, so today the tool covers comment keyword triggers only.
