How it works
Approve access on Instagram's own screen. Business or Creator account, no password shared, revoke whenever you like.
Pick the post, choose the trigger word, write the DM and drop in your link. Whole-word or partial matching, one keyword or many.
Every matching comment gets a public reply and a private DM within seconds — and the email lands in your contacts.
The whole flow
This is the entire automation, exactly as your followers experience it — from the comment on your post to the email in your contacts.

Features
Match one keyword, a list of them, or every comment on the post. Whole-word or partial, set per campaign.
A visible reply under the comment and a private DM to the commenter, sent in the same moment.
Ask for an email inside the DM. Answers are validated, stored against the contact and ready to export.
Require a follow before the link goes out, checked against Instagram's own follow status.
Swap any URL for a tracked redirect and watch clicks and click-through rate per campaign.
Every conversation in one place, across multiple connected accounts, so you can jump in by hand any time.
Yes, when it runs on Instagram's official API — which is what FastReply uses. Private replies to comments are a sanctioned feature of that API. What gets accounts flagged is scraping and browser bots, neither of which happen here.
FastReply never asks for your password and never drives a browser. You approve access on Instagram's own screen, sending stays under the documented cap of 750 private replies per hour, and you can revoke access from Instagram at any time.
Comments arrive by webhook and the DM is queued the instant one matches a keyword, so it normally lands within a second or two of the comment being posted.
Replies are queued and drained under the hourly cap instead of being fired all at once, so a spike gets worked through steadily rather than throttled or dropped.
A Business or Creator (professional) account. Personal accounts cannot use Instagram's messaging API at all. Switching is free in Instagram settings and takes about a minute.
No. Connect your account in the browser and your first automation can be live in a couple of minutes. Nothing to install, no code to write.
Start free, connect your account, and have the first automation running in a few minutes.
