A launch fails in one of two ways. Either not enough people know it is happening, or the people who know are not the people who would buy.
Comment-to-DM addresses both, because it builds a list of people who actively asked to hear about the thing, and gives you a channel that reaches them directly rather than hoping the algorithm shows them your story.
Here is the structure that works, stage by stage.
Stage 1 — Waitlist, three to four weeks out
Start collecting before you have anything to sell.
Keyword: WAITLIST
The post: teach something small and genuinely useful from inside the course, then say the full version is coming.
The DM: confirm they are on the list, and give the actual date.
You're on the list ✅ Doors open on the 14th at 10am.
Quick one — what's the main thing you're hoping this fixes?
That question is the most valuable thing in the entire launch. The answers tell you what to teach during the content phase, what objections to handle, and what words to use in the sales page — in your buyers' language rather than yours.
Read every reply. This is not a step to automate past.
Stage 2 — Content phase, two weeks out
Now teach in public. Three or four posts that solve a real problem, each with a different trigger keyword so you learn what people care about.
Keywords: something specific per post — FRAMEWORK, CHECKLIST, TEMPLATE.
The DM: deliver the resource, then mention the waitlist once, briefly.
Here's the framework 📋
(Doors for the full programme open Tuesday — you can join the waitlist by replying WAITLIST if you want the heads-up.)
Deliver first. The launch mention is a postscript, not the point. People who came for the checklist and got a sales pitch remember that.
Track which keyword pulls hardest. The topic that produces the most comments is the one to lead your sales copy with.
Stage 3 — Cart open
Keyword: ENROL or DOORS
The DM: the checkout link, immediately, with the price and what is included. No qualifying, no funnel, no booking call.
Doors are open 🚪 [link]
₹X for the full programme — eight modules, live calls on Thursdays, lifetime access.
Also message the waitlist directly. That is the entire reason you built it — these are people who explicitly asked to be told, and reaching them does not depend on the algorithm.
Stage 4 — Objection posts, mid-cart
The middle of a launch is where most people go quiet, and it is when the undecided are deciding.
Post about the specific objections you collected in stage 1. "Is this for beginners?" "What if I can't make the live calls?" "How is this different from X?"
Keyword: QUESTION or the specific topic.
The DM: the honest answer, then the link.
Honest includes telling people it is not for them. A launch where nobody is disqualified has a refund problem coming.
Stage 5 — Cart close
Keyword: LAST or CLOSING
Final post, final DM to the waitlist, and then actually close it. Scarcity works exactly once if it is not real — reopening "just for you" the next day teaches your audience to ignore every future deadline.
What to do with people who did not buy
Most of your waitlist will not buy, and that is normal. What you do next determines whether the next launch is bigger.
Do not delete the list. These are people who raised their hand for this exact topic.
Do not roll them into a general newsletter without asking. They consented to launch updates, not a weekly email. Ask once, plainly.
Do ask why. A short message — "totally fine if the timing was wrong, mind telling me what stopped you?" — gets more honest answers than any survey. Price, timing and confidence are the usual three, and they need different fixes.
The seven-day problem, during a launch
Instagram allows one private reply per comment, within seven days of that comment.
During a launch this matters more than usual. A waitlist post from three weeks ago that is still collecting comments cannot be answered automatically, and those people asked to be told about your launch and heard nothing.
Two habits: re-post the waitlist ask rather than relying on an old post, and check older launch posts by hand near cart open.
Realistic numbers
The mistake is expecting comment volume to predict sales. It does not.
A waitlist post that pulls 600 comments and a sales post that converts 4 of them is a worse launch than 90 comments converting 11. Comments measure interest in the free thing; only the follow-up question and the reply rate tell you about intent.
Track: waitlist size, reply rate to your stage-1 question, cart-open DMs delivered, and sales. The reply rate is the best early predictor you have — if almost nobody answered the question in stage 1, the launch is unlikely to convert well, and you have two weeks to fix the offer rather than discovering it on cart-open day.
The short version
Waitlist early with one open question. Teach for two weeks with distinct keywords. Send the link the moment doors open, and message the waitlist directly. Handle objections in public. Close when you said you would.
The mechanic is ordinary comment-to-DM automation — what makes a launch work is the question in stage 1 and actually reading the answers. More campaign structures in 15 comment-to-DM campaigns.
