What to Send Your Waitlist: A Simple Follow-Up Plan

Short templates for people who joined, went quiet or left at checkout, a stop rule for replies on any channel, and the CAN-SPAM basics to include.

By , Founder, Baljia AI

The short answer

Send each person a short note from a real person's address, with one question they can answer in a line. Send three notes at most, over about two weeks. Treat three groups differently, because each told you something different: people who joined a waitlist, people who signed up and went quiet, and people who left at checkout.

The moment anyone replies, on any channel, stop everything else. Every commercial email must carry your postal address and a working opt-out, and must say it is an ad unless the person gave prior affirmative consent.

The goal is a conversation, not a sale. No template can promise a reply, but these make replying easy. AI for founders is useful here: it can draft these notes, as long as you read each one before it goes.

Split the list first

A single "we're live" email to everyone wastes the most useful thing you know, which is how far each person got.

GroupWhat they told youYour jobWhen to start
Waitlist"I want this when it exists"Learn what they want firstWithin a day, or today if the list is old
Signed up, went quiet"I tried, and something stopped me"Get them past the first stepAbout two days after they stop
Left at checkout"I nearly paid"Remove the snagThe same day

Keep one sheet with one row per person, not per channel:

NameEmailGroupJoinedLast note sentStop?
Sam Lee[email protected]QuietOct 12Note 1, Oct 16No

"Stop?" turns to Yes when they reply, opt out, buy or bounce. (Sam is invented, as is everything in the examples below.)

The templates

All of these were written for this post. Replace everything in brackets. Send from your own name and address, never a no-reply box, and only say what is true. None of these notes is complete as shown: each one still needs the three-line footer in the CAN-SPAM section below, with an ad line, your postal address and an opt-out.

Waitlist: three notes over 12 days

Note 1, within a day. Subject: Quick choice for [product]

Hi [name], I'm [your name], and I'm building [product]. Thanks for joining the list.

I can only finish one of these first: [option A] or [option B]. Which would you use sooner?

One word is plenty. I read every reply.

Note 2, day 5. Subject: What [product] looks like so far

Hi [name], here is [a screenshot or a short video] of [the one part that works today].

Would this have helped with [specific job] last month? A yes or no is fine.

Note 3, day 12. Subject: Your spot on the [product] list

Hi [name], this is my last note until we open, and you keep your place either way.

If you would rather try it early and tell me what is broken, reply "early".

We like a forced choice on a waitlist, as a judgment call, because it is easy to answer and it tells you something about what to build. Offer two options you are truly deciding between.

Signed up, went quiet: three notes over 14 days

Note 1, day 2. Subject: Your [product] account

Hi [name], you set up your account on [day] and stopped before [first useful step]. That step can be fiddly.

If you send me [the one thing needed], I'll do it for you and reply with the link.

Note 2, day 6. Subject: Wrong tool?

Hi [name], honest question: is [product] the wrong fit for what you needed, or did the week just get away from you? Either answer helps me.

Note 3, day 14. Subject: Closing the loop

Hi [name], I'll stop checking in now. If [job] comes back around, reply to this email and I'll help you start.

Offering to do the first step is the point of this sequence. It costs you a few minutes, and you find out what stopped them.

Left at checkout: three notes over 5 days

Note 1, the same day. Subject: Did checkout work for you?

Hi [name], your order for [plan] did not finish. Sometimes that is our fault. Did something break? If so, I'll fix it today.

Note 2, day 2. Subject: What people ask before buying

Hi [name], here is a question I get before people buy: [real question from your inbox]. The short answer is [real answer].

Is there anything else you would want to know first?

Note 3, day 5. Subject: Last note on your order

Hi [name], I won't keep writing about this. [Plan] will be here when you are ready. If a smaller start would help, [smaller option, if you have one].

Assume a technical problem first. It is a kinder opening, and now and then you will find a real bug.

The stop rule

This is the part that keeps a follow-up plan from feeling like spam. A reply anywhere ends the plan for that person, everywhere.

What happensWhat you do
A human replies on any channelStop all steps and answer them yourself
They book a call or buyStop all steps and move them to onboarding
They opt out, anywhereStop on every channel and keep them on your do-not-contact list for good
Out-of-office replyPause until their return date
The email bouncesRemove the address
A colleague answers for themStop, and treat the colleague as a new person

Doing it by hand. Each morning, check your inbox and any other channel you use before you send anything. Update the "Stop?" column, then send only to rows marked No. It takes about ten minutes for a small list.

Doing it with a tool. Ask how a reply on one channel cancels a step on another, then test it. Add your own second address as a contact, reply from it, and see whether the next step still goes out.

Which channel to use

Email is the default, because they gave it to you. Use another channel only when you have a clear reason:

  • LinkedIn or X: only if they gave you the handle, or you are certain it is the same person. A similar name is not enough.
  • Text or WhatsApp: only if they agreed to hear from you there.
  • More than one channel: keep a gap of a few days, and never repeat the same words. Being followed around three apps in one afternoon feels strange.

CAN-SPAM basics

CAN-SPAM is the US law for commercial email. We are not lawyers, so treat this as a starting list and get advice if email is a big part of your business. The FTC's compliance guide and the statute say:

  • Each commercial email includes a valid physical postal address. A street address, a registered PO box or a registered private mailbox qualifies.
  • Each email gives a clear and conspicuous way to opt out.
  • The opt-out keeps working for at least 30 days after you send.
  • You honor opt-out requests within 10 business days.
  • Opting out costs nothing and takes no more than a reply email or one web page.
  • The email is clearly identified as an ad, unless the recipient gave prior affirmative consent.

The FTC guide puts the penalty at up to $53,088 per violating email, so a list makes a small mistake expensive.

Whether a waitlist signup counts as prior consent depends on what your form said, and the quiet and checkout groups may never have agreed to marketing. So add this whole footer to every note, and drop the first line only if a lawyer has confirmed consent:

This is a marketing email from [business name]. [Street address or registered PO box], [city, state, ZIP]. Reply "stop" and I will take you off this list.

When they reply

A reply is the whole point, so answer quickly and in person.

They sayYou send
"Not yet""Thanks. When should I check back?" Put the date in your sheet
"Too expensive""Fair enough. What were you comparing it with?"
"What does it do, exactly?"Two lines, in their words, no brochure
A feature requestNote who asked, and tell them if you ship it
"Yes, let's talk"Your calendar link, right away

Read these replies as research. If three people ask about the same missing feature, or stall on the same step, that matters more than your open rates.

What not to send

  • A discount in the first note. You have not learned why they paused, and they learn to wait.
  • Fake urgency. "Only 3 spots left" is a false claim if there are plenty.
  • A newsletter. Five links and a founder update do not get replies. One question might.
  • A fourth reminder. If three short notes did not land, a fourth will not fix that.

If the list is months old

People forget what they signed up for, so reintroduce yourself. Use this as your only first note, add the same footer, and send to a small batch before the whole list, because old addresses bounce.

Hi [name], you signed up for [product] back in [month]. Since then we have [one true sentence on what changed].

Still interested, or should I take you off the list?

Removing someone who says no is a good outcome. A smaller list of people who want to hear from you is worth more.

Where Baljia fits

This plan is easy to run by hand for fifty people and tiring for five hundred. Baljia can draft these follow-ups, pace them and stop when someone replies, and you approve what goes out. Test how it handles a reply on a second channel before you rely on it, the same way you would with any tool. Its LinkedIn outreach comes with Growth and Scale, not Starter or the free trial.

If Baljia built your app, there is a wrinkle in the third group. Apps can take bookings and orders, but card checkout into your own payment account is not available yet. So your "left at checkout" list would be people who left a booking or order form. The same notes apply. See how it works on the AI sales outreach page.

If you have no list at all, start with the one-day exercise. Before any draft goes out, the review checklist takes about two minutes.

Frequently asked questions

How soon should I email people on my waitlist?

Within a day of signup. They still remember why they joined, and the note can come from you in person. If the list is already old, start today with the reintroduction note above.

How many follow-up emails should I send?

Three at most, over about two weeks. Stop sooner if they reply anywhere. That number is our judgment, not a rule of law, but short plans are easier on your buyers and on your name.

What should I say to someone who abandoned checkout?

Ask whether something broke. It is a kind opening, and it may turn up a real bug. After that, answer one real question buyers ask, then send one last note and stop.

Does CAN-SPAM apply to waitlist emails?

Assume it does for anything that promotes your product. Include an ad line, your postal address and an opt-out in each email. Only prior affirmative consent removes the ad line, and whether a signup counts depends on your form's wording, so ask a lawyer if you are unsure.

Should I offer my waitlist a discount?

Not in the first note. Learn what they want first. If you do offer an early-access price later, make sure it is real, and that the end date is true.

Can I message waitlist signups on LinkedIn?

Yes, by hand, if you are certain it is the right person. Do not guess a profile from a name. Any tool that automates LinkedIn from your account also carries account risk, which our safety post explains.
