Miz DMYes, you can automate Instagram DMs for free. The catch is the limit. Free plans reply to comments with a DM, but they cap how many people you can reach each month. Often it is low enough that one good Reel uses up the whole month. This guide shows what each kind of free option actually gives you, so you can pick one that won't break mid-campaign.
All prices and limits below were checked on 4 October 2026 on each tool's own pricing page. They change often, so check again before you commit.
What "free DM automation" usually means
Most people searching for this want one thing: someone comments a word like PRICE or LINK on a Reel, and they get a DM with the link automatically. That is called comment-to-DM. Read how comment-to-DM works for the full setup.
There are three free routes:
- Instagram's own tools (free, limited)
- Free plans of DM automation tools (free, capped)
- A cheap paid plan (₹99–₹500 a month, usually worth it once you post regularly)
Every comment, story reply and DM answered instantly, every person saved as a lead in MizUp CRM, and Miz AI replying for you.

Inside the Instagram app and Meta Business Suite, a professional account can set up:
| Feature | What it does | Comment-to-DM? |
|---|---|---|
| Instant reply | Auto-replies to the first message someone sends you | No |
| Away message | Replies when you are offline | No |
| FAQs / conversation starters | Tap-able questions at the start of a chat | No |
| Saved replies | Shortcuts you send manually | No |
Good for: answering "Hi, price?" messages faster. Not good for: Reel campaigns. None of these fires when someone comments.
Route 2: Free plans of DM automation tools
| Tool | Free plan limit | Accounts | Notes |
|---|---|---|---|
| ManyChat Free | 25 active contacts / month, 4 automations | 1 per channel | Paid plans billed in USD from $14/month |
| LinkDM Free | 1,000 DMs / month | 1 | Paid from $19/month |
| InstantDM | 7-day free trial, no ongoing free plan | — | Paid from $9.99/month |
| MizUp (Miz DM) Free | 50 DMs / month, 20 AI replies (trial) | 1 | Leads saved to a CRM; "Sent via MizUp" footer |
What to compare, beyond the headline number:
- DMs vs contacts. "25 contacts" means the 26th person who comments gets nothing. "1,000 DMs" is easier to plan around.
- Branding. Free plans often add a "sent via" footer to your DM.
- Follow gate. Asking people to follow before getting the link is usually a paid feature.
- Story and Live triggers. Mostly paid.
- Where the lead goes. A DM that just sends a link is easy. Knowing who clicked, following up and closing the sale is the hard part, and that is where a CRM helps.
Route 3: When paying ₹99 is cheaper than "free"
Free stops being free when:
- a Reel takes off and your cap runs out halfway through the comments (those people never get the link),
- you have to copy leads out of Instagram by hand, or
- the "sent via" footer makes a premium brand look small.
MizUp Miz DM Starter costs ₹99/month + GST. It includes 5,000 DMs, story, Live and DM keyword triggers, a follow gate and email gate, no branding, and every lead saved in MizUp CRM. Paid plans start with a 7-day free trial. See the full Instagram DM automation pricing comparison.

Safety checklist for any free tool

- It never asks for your Instagram password.
- It only DMs people who commented, replied or messaged you first.
- It does not promise "unlimited DMs to any user".
More on this: is Instagram DM automation safe?
Bottom line
Use Instagram's free tools for basic replies. Use a free DM tool to test comment-to-DM on one Reel. Once a campaign actually brings sales, move to a plan whose cap won't run out during your best post. Try Miz DM free, no card needed.
Frequently asked questions
Is there a free Instagram DM automation tool?
Yes. Several tools have free plans that send a DM when someone comments a keyword. Limits differ a lot: ManyChat Free covers 25 active contacts a month, LinkDM Free covers 1,000 DMs a month on one account, and MizUp Free covers 50 DMs a month with leads saved to a CRM.
Does Instagram have free built-in DM automation?
Partly. Through the Instagram app and Meta Business Suite you can set instant replies, away messages and FAQ buttons for people who message you. They do not send a DM when someone comments a keyword on your Reel. For that you need a tool built on the official Instagram API.
Is free DM automation safe for my account?
It is safe if the tool connects through the official Meta login and never asks for your Instagram password. Avoid any free tool that wants your password or promises to DM people who never interacted with you.
What is the catch with free plans?
Usually a low monthly cap, a "sent via" footer in your DMs, no follow gate, one account only, and no story or live triggers. If one Reel goes viral, a free cap can run out in an hour.
When should I upgrade from a free plan?
Upgrade when you regularly hit the monthly cap or when a single campaign is worth more than the plan price. In India, paid plans start at about ₹99 a month.
