Instagram auto DM for every comment
Someone comments a keyword on your post or reel, and Postflow sends them your link in a DM within seconds. Capture their email, answer with AI and track every lead.
How comment-to-DM works
Pick a post or reel
Choose any post or reel on your Instagram Business or Creator account, or one you are about to schedule.
Set a keyword like GUIDE
Tell followers to comment a word such as GUIDE, LINK or PRICE. Match it exactly or anywhere in the comment.
The DM goes out in seconds
Everyone who comments the keyword gets your message and link in their DMs, day and night.
What you can automate
Keyword replies
Send a different DM for each keyword, on one post or across all of them.
Email + phone capture
Ask for an email or phone number before the link is sent, so every comment becomes a lead.
Follow gate
Only send the freebie once the person follows you, to grow your audience with every post.
Story replies
Reply automatically when someone answers your story with a keyword.
AI follow-up replies
When people reply with a question, AI answers in your voice and keeps the chat going.
Click + lead tracking
See DMs sent, link clicks and leads collected for every post.

Is Instagram auto DM safe?
Yes, when it runs on the official Meta API. Postflow connects through Meta's own login, so we never see or store your Instagram password. We only message people who commented or replied first, we respect Meta's rate limits, and we follow the 24-hour messaging window: replies are sent while the conversation is open, never as cold spam.
Instagram auto DM questions
How do I auto DM people who comment on Instagram?
Connect your Instagram Business or Creator account to Postflow, pick a post, set a keyword and write your message. Everyone who comments that keyword gets the DM automatically.
Will auto DMs get my Instagram account banned?
Not when you use the official Meta API. We never ask for your password, we respect Meta's rate limits and we only message people who commented first.
Is Postflow a ManyChat alternative?
Yes. Postflow does comment-to-DM automation, email capture and AI replies, and also schedules your posts, so you can use one tool instead of two.
Do I need an Instagram business account?
Yes, Meta only allows DM automation on Business or Creator accounts. Switching is free and takes about a minute in the Instagram app.
