What you can automate for free
Six Instagram DM flows you can set up today — all on the free plan.
Post "Comment LAUNCH to get early access." Every commenter gets an instant DM with your link — while you sleep.
Filter DM inquiries automatically. Qualify budget, ask for email, book a call — before you even see the conversation.
Auto-reply to every comment with a personalised response that sounds like you. Boosts post reach via the algorithm.
Bypass the "link in bio" friction. Drop a keyword in your caption — every person who comments gets the link instantly via DM.
Train Voice DNA on your FAQ. When DMs ask "how much does it cost?" or "do you ship to X?" — the AI answers in your tone, instantly.
Comment to unlock: "Comment INFO to get the free guide." Deliver exclusive content only to people who engage — free gated funnels.

Frequently asked questions
Is Instagram DM automation really free forever?
Yes. PostEngage.ai offers a genuine free-forever plan — unlimited basic comment and DM automation, no contact limits, no expiry. AI credits (100 free on signup) are the only consumable; basic rule-based triggers are unlimited.
What is included in the free plan?
Keyword-triggered DMs, comment reply automation, story mention flows, welcome DMs, conversation inbox, 100 AI credits, Voice DNA training, and analytics. No credit card required.
Will automating DMs get my Instagram account banned?
No — as long as you use the official Meta API, which PostEngage.ai does exclusively. We never use browser automation or scraping. You are in full compliance with Meta's platform policies.
How is this different from ManyChat's free plan?
ManyChat reduced its free plan to 25 contacts in March 2026 — making it practically unusable. PostEngage.ai has no contact cap on the free plan. You can automate DMs with 1,000 followers or 1 million.
What happens when I use up my 100 free AI credits?
Basic rule-based automations keep running with no interruption. Only AI-generated personalised replies need credits. You can top up starting at ₹749 (about $9) — a one-time purchase, no subscription.
Do I need a business Instagram account?
Yes. Instagram DM automation via the Meta API requires a Professional account (Business or Creator). If you are still on a Personal account, you can switch for free in the Instagram settings in under 60 seconds.
