How to Write a "Comment and I'll DM You" Reel CTA

You set up comment-to-DM automation, posted the reel, and… a handful of comments. Usually the automation isn't the problem. The call to action is. Viewers didn't see it, didn't understand what they'd get, or didn't believe it would actually arrive.

A good “comment X and I'll DM you” CTA lives in four places at once: the spoken line, the on-screen text, the caption and the pinned comment. Here's how to write each one, with copy you can lift directly.

The formula behind every CTA that works

Comment [KEYWORD] + and I'll DM you [specific thing] + [small reason to do it now]

Three examples:

• “Comment MENU and I'll DM you this week's thali menu with prices.”
• “Comment PLAN and I'll send you the 4-week home workout chart — free.”
• “Comment VISIT and I'll DM you the site-visit slots for this weekend.”

The specific thing matters most. “Comment INFO for details” is vague; “Comment INFO and I'll send the size chart and COD charges” tells them exactly why it's worth typing four letters. Still choosing the word? See 60+ reel comment keyword ideas.

1. The spoken line: say it, don't just show it

Many viewers watch with sound on but never read the caption. Say the CTA out loud, slowly, and spell the keyword if it could be misheard.

Where to put it:

• Early mention (first 5–8 seconds) for reels where the payoff is the freebie: “Stay till the end, and if you want the full list, comment LIST.”
• End mention for product reels, after you've shown the product: “Price aur link chahiye? Comment PRICE, main DM kar deti hoon.”

Say it like you talk. Hinglish is fine if that's your voice: “Neeche LINK likho, seedha DM mein bhej dunga.” Don't switch to formal English only for the CTA — it sounds like an ad.

2. On-screen text: the part people actually read

Put the keyword on screen in big, high-contrast text for at least two to three seconds. Keep it out of the bottom strip where Instagram's caption and buttons cover it, and away from the right edge where the like and comment icons sit.

On-screen text options:

• “Comment 👇 PRICE”
• “Want the PDF? Comment GUIDE”
• “Type MENU — I'll DM you”
• “LINK in DM → comment SHOP”

If the reel has a hook overlay at the start, don't cram the CTA into it. Hook first, CTA near the end or as a second overlay.

3. The caption: the first line does the work

Only the first line or two of a caption shows before “more”. Put the CTA there, not under twelve hashtags.

Caption template (product):

Comment PRICE and I'll DM you the price + order link 📩

Handblock cotton kurtas, sizes S to XXL, COD available across India.

(Don't see it? Check your message Requests.)

Caption template (creator / coach):

Comment SCRIPT and I'll send you the exact 5 hooks I used this month — free.

Save this reel so you can come back to it.

Caption template (Hinglish, local business):

MENU likho comment mein, poora menu rate ke saath DM mein aa jayega 🍛

Delivery: Andheri, Bandra, Juhu.

That bracket line about Requests is worth keeping. People who don't follow you may see your message in their Requests folder rather than the main inbox. Telling them to check Requests saves a lot of “didn't get it” comments.

4. The pinned comment: your backup CTA

Pin a comment from your own account as soon as the reel goes live. It catches people who scroll comments before reading the caption.

• “👉 Comment PRICE below and check your DMs (or Requests) in a few seconds.”
• “Sab ko DM ja raha hai — bas GUIDE likho 👇”

Don't pin a comment that contains the keyword in a way your own automation might try to answer. Your own comments are usually ignored, but test it once so you're sure.

The public reply: proof that it works

When someone comments, the automation can reply publicly under their comment and send the DM. That public reply is part of your CTA — it shows the next viewer that the DM really arrives. Write three or four variations so the comment section doesn't look copy-pasted:

• “Sent! Check your DMs 📩”
• “DM kar diya, dekh lo 🙌”
• “Done — it's in your inbox (or Requests).”
• “Check DMs, details bhej di hain ✨”

JaldiDM rotates between public reply variations for you. Setup steps are in Instagram auto reply to comments.

The DM itself: deliver what the CTA promised

A CTA that promises “the price” and a DM that says “Hi! Thanks for your interest, visit our website” burns trust. Match the promise exactly:

Hi! Here's the price you asked for 👇

Handblock kurta — ₹899 (free shipping above ₹1,500)

[Button: Order now] [Button: Size chart]

If you want people to follow before getting the link, say so in the CTA too, so the extra step doesn't surprise them. The trade-offs are in follow-to-get-link: when it helps and when it hurts.

A quick checklist before you post

1. Keyword is the same in the spoken line, on-screen text, caption and pinned comment.
2. The automation is live on this reel (or on All posts) with the same keyword plus common variants.
3. You've tested it by commenting from a second account.
4. The DM gives exactly what the CTA promised, in the first message.
5. Someone on your team checks the inbox for replies that need a human — complaints and custom requests shouldn't sit unanswered.

If you're testing and nothing arrives, run through Instagram DM automation not working.

Write it once, reuse it forever

Once you find a CTA that fits your voice, keep it. Same keyword for the same offer, same rhythm, same reply style. JaldiDM's 7-day free trial (no card) is enough to test a few reels and see which wording your audience responds to. Try it free.
