Comment "LINK" and get the link in your DMs. That little trick creators use everywhere is Instagram DM automation — and ManyChat's free plan is enough to set it up yourself in about 15 minutes. Here is the full setup, step by step.
What the ManyChat free plan actually includes
ManyChat is an official Meta Business Partner, which means its Instagram DM automation is approved and safe to use — you are not risking your account by connecting it. The free plan gives you:
- The visual flow builder with drag-and-drop blocks (no coding)
- Keyword triggers and comment-to-DM automations
- Welcome messages and a default reply
- Basic growth tools for capturing leads
The free tier historically covered up to 1,000 contacts with basic features, and signing up requires no credit card. One honest caveat: in 2026 some accounts report seeing a tighter free limit (around 25 active contacts), a change that appears to have rolled out gradually rather than to every account at once. So before you plan a big campaign, check the current limit in your own ManyChat dashboard under Settings → Billing. If the free tier is too tight for your volume, this article still helps — the setup below works identically on the paid plans, and there are free competitors like ReplyRush (up to 1,500 DMs per month on its free tier) and LinkDM (up to 1,000 DMs per month) if you just need volume.
What you need before you start
ManyChat cannot automate a personal Instagram profile — Instagram's API only allows this for certain account types. You need:
1. An Instagram Business or Creator account. Switch in the Instagram app: Settings → Account type and tools → Switch to professional account. It is free and takes a minute.
2. A Facebook Page linked to that Instagram account. This is the bridge ManyChat uses to connect. Create a page at facebook.com/pages/create if you do not have one, then link it in the Instagram app under Settings → Accounts Centre.
3. A ManyChat account. Sign up at ManyChat.com using your Facebook or Instagram login.
Step 1 — Connect your Instagram account to ManyChat
After signing up, ManyChat asks which channels you want to add. Select Instagram and log in through Facebook to grant permission to your linked Page and Instagram account. ManyChat will list every Facebook Page you manage — pick the one connected to the Instagram account you want to automate. Once connected, test it: ManyChat usually shows a green "Connected" status, and you can send yourself a DM to confirm the channel is live.
Step 2 — Set your default reply and welcome message
Before building anything clever, handle the basics so nobody ever hits a dead end:
- Default reply: In Settings → General, write a short fallback message like "Thanks for reaching out! I usually reply within a day — in the meantime, what can I help you with?" This fires when a message matches none of your automations.
- Welcome message: This is the first thing new subscribers see when they message you. Keep it friendly and tell them what they can get: "Hey! Welcome. Reply GUIDE and I'll send you my free growth checklist."
Both live in the Automation tab. A good default reply alone makes your account feel responsive even before you build full flows.
Step 3 — Build your first keyword automation
This is the core of Instagram DM automation, and the free plan includes it. Here is the classic "comment LINK" flow, recreated in about five minutes:
1. Go to Automation in the left sidebar and click New Automation.
2. Choose the Instagram template for "Instagram Comments" (ManyChat ships premade templates — start from one instead of a blank canvas).
3. Pick the trigger. You have two options:
4. Choose where it runs. Apply it to a specific post (safest for your first run) rather than all posts, so you can control the volume.
5. Build the flow with blocks. A simple flow is three blocks: a Text block ("Here's your free checklist!"), an Attachment or button block with the download link, and a final Text block asking a follow-up question ("Want part 2? Reply PART2"). Drag blocks from the sidebar and connect them in order.
6. Add a public reply. For comment triggers, ManyChat can also auto-reply to the comment itself ("Just sent it to your DMs!") — this keeps engagement visible on the post.
7. Publish and test. Toggle the automation live, then test it from a second account (or a friend's): comment your keyword on the post and confirm the DM arrives.
- Keyword trigger: fires when someone DMs you a specific word like "GUIDE" or "LINK".
- Comment trigger: fires when someone comments a keyword on one of your posts or Reels, and ManyChat opens a DM with them. This is the automation behind every "comment YES" post you have seen.
Most users get a working bot within 10 to 15 minutes because the flow builder is genuinely simple — you are arranging boxes, not writing code.
Step 4 — Add the automations that actually move the needle
Once the first flow works, these are the highest-value automations for creators and small businesses:
- Lead magnet delivery: comment keyword → DM with the freebie → ask for email inside the DM. You build your list while you sleep.
- Story mention auto-replies: when someone mentions your brand in their story, ManyChat can thank them automatically. Great for user-generated content campaigns.
- FAQ automation: keyword triggers like "PRICE", "HOURS", or "SHIPPING" that instantly answer the questions you get ten times a day.
- Follower welcome: an automatic greeting when someone new messages you, pointing them to your best content.
- Post-purchase or booking follow-up: if you sell through Instagram, a flow that confirms orders and answers "where is my order" questions.
Keep every flow short — three to five messages max. Long chatbot interrogations annoy people; short flows convert.
Stay inside Instagram's rules (the 24-hour rule)
Automation does not exempt you from Meta's messaging policies, and this is the part most beginners miss:
- The 24-hour rule: Meta requires that promotional messages on Instagram and Messenger be sent within 24 hours of the subscriber's last interaction. If more than 24 hours have passed, you can only send non-promotional messages — unless the person has opted into your marketing messages.
- Do not spam keywords everywhere. Trigger words on every single post look desperate and train your audience to tune out. Reserve DM automations for posts that actually offer something.
- Never buy engagement pods or fake comments to feed automations. Automating genuine engagement is allowed; manufacturing it is not, and Instagram can restrict accounts for it.
- Let humans take over. If a conversation gets complicated or emotional, your default reply and flows should hand off to a real person. ManyChat lets you pause automation for a specific contact.
Because ManyChat is an approved Meta partner operating through the official API, using it the way it was designed is the safest form of automation there is. Problems start when people use it to blast unsolicited promotional messages — so don't.
When the free plan runs out: what Pro costs
Upgrade only when the free tier is genuinely the bottleneck. Signs you need it: your automations keep hitting the contact limit, you need unlimited keywords and tags, you want integrations (Shopify, Mailchimp, Google Sheets), or you need the deeper analytics. ManyChat Pro starts at $15 per month and scales with your contact count (for example, around $45 per month at 5,000 contacts). There is a 7-day free trial and a 30-day money-back guarantee, so you can test Pro risk-free before committing.
The smart play for most beginners: run everything on the free plan for a month, measure how many contacts you actually collect, then decide whether Pro pays for itself. If DM automation is driving real revenue, $15 is cheap. If it is not, the problem is your offer, not your plan.
