About

Someone comments NEWSLETTER, taps once in your DMs and gets your Substack, beehiiv, Kit or Mailchimp sign-up page, with one reminder if they wait. Copy it.

Ask for the word NEWSLETTER in the comments of your next post. Each person who comments it gets a DM asking if they want to join, and a tap on "Yes, send it" brings your sign-up page. They subscribe on your newsletter tool's own page. If the page stays unopened, one reminder follows 2 hours later.

What the template does, step by step

1. Someone comments NEWSLETTER

The flow listens to top-level comments on one post and ignores replies under other comments. Capitals and accents make no difference, and NEWSLETTER only has to appear as a whole word, so "Newsletter please" counts, and so does "newsletters". Each DM goes out on Inrō's comment to DM feature.

The comment then gets a visible answer, drawn at random from three: "Sent, check your DMs", "Just sent it to your DMs" and "It's in your DMs now 🙂". It is posted after the DM, never before. Public reply plus DM: 46% conversion. DM alone: 29%. Those figures come from the 798,041 conversations in Inrō's DM Benchmark, not from this template.

One post is in scope: the first you share once the trigger's date is behind you. That date is filled in when you copy the template; setup check 1 below resets it.

2. The first DM asks if they want to join

The opener asks "Want to join the newsletter? Tap below." over a single "Yes, send it" button.

That single message is all a comment allows at first: Meta's private replies open the chat, and it only continues if the person answers (Meta for Developers, checked 22 October 2026). Here the answer is a tap. It is the reader saying yes to your newsletter, and it lets the sign-up page and the reminder through. Without a tap in the next 6 hours, the flow goes quiet for that reader.

3. Your sign-up page arrives as a link card

Next comes a link card called "Newsletter sign-up", with "Join the newsletter" as its button. It points to an example address until you paste your own. The reader subscribes on your newsletter's own page, so the address goes straight into your newsletter tool, not into Inrō.

4. A folder of everyone who opened it

"Newsletter: clicked" collects everyone who taps "Join the newsletter". A late tap counts too, even one that comes after the reminder.

5. One reminder after 2 hours

Readers who leave the card closed for 2 hours get a single follow-up, "Have you checked the link yet?". Anyone who already tapped "Join the newsletter" is skipped. The wait decides when that follow-up is sent and nothing else: the sign-up page stays reachable from the card.

Which sign-up page to use: Substack, beehiiv, Kit, Mailchimp or your own site

Any web page fits in the card. Use your Substack, beehiiv, Kit or Mailchimp sign-up page, or a form on your own site. There is nothing to connect between Inrō and your newsletter tool, and readers sign up with whatever confirmation step that tool already uses.

Would you rather collect the address inside the DM? Grow your email list from comments asks "What's your best email? Your checklist comes right after." and checks the format before it sends the link. This template keeps the sign-up on your own page.

What to change before you turn it on

Your copy listens for NEWSLETTER in top-level comments on your next post, and nobody goes through it twice.

Six details to adjust before you post:

The trigger date. "Next post only", under "Select the posts" in the comment trigger, shows the date the flow counts from. Press Reset date, then Save scenario, just before you publish your NEWSLETTER post. Then turn the scenario on.
The keyword. Keep NEWSLETTER or use your newsletter's name, and ask for it in your caption.
The opener. Swap "the newsletter" for the name of yours, so readers know what they are joining.
The sign-up link. Swap the example address in the card for your sign-up page from Substack, beehiiv, Kit, Mailchimp or your own site.
The card's title and button. "Newsletter sign-up" and "Join the newsletter" work as they are. Put your newsletter's name in them if it has one.
The folder. Rename "Newsletter: clicked" to match.

Neither wait is fixed: the button gives 6 hours, the reminder comes after 2, and you can set your own. On the free plan you can run up to 3 automations at once.

Best tips for your scenario

Say what readers get in the opener. Name the topic and how often an issue lands. The "Yes, send it" button is how a reader opts in to the flow, so the opener is your one line to explain the newsletter before they decide. Keep it short: the default is 39 characters.
Give the keyword its own post and say it out loud. Put NEWSLETTER in your caption and on screen. If another automation listens for the same word on the same post, change one keyword, or put both in a priority folder: when several automations in that folder match one comment, only the one highest in the list runs. The comment to DM keyword planner helps you pick a word.
Point the card at the sign-up form, not your homepage. The card is the last step before someone subscribes. Any page works, so send readers to the page where the email field is.
Pair the newsletter with a freebie. If you have a guide or checklist to give away, run a separate freebie flow on another post with its own keyword, and mention your newsletter in that post too.
Decide what happens when you chat by hand. The template keeps running for someone you message yourself, so the reminder can still go out. "Interrupt when you reply manually" is off here; if your own message should end the flow for that reader, switch it on in the scenario settings.

FAQ

How do I promote my newsletter on Instagram?

Ask for a keyword in a post and send your sign-up page by DM to everyone who comments it. This template does that with NEWSLETTER.

How do I link my newsletter or Substack to Instagram?

Put the address of your sign-up page in this template's "Newsletter sign-up" card. A Substack, beehiiv, Kit or Mailchimp page works, and so does a page on your own site. Nothing needs connecting.

Can I see who subscribed?

Inrō sees who opened the sign-up page: those people are in the "Newsletter: clicked" folder. Who actually subscribed shows in your newsletter tool.

Can I collect the email in the DM instead?

Yes, with Grow your email list from comments, which asks for the address and checks it before it sends the link. This template sends people to your own sign-up page instead.
