A count of real people.

A sign-up only counts once the person confirms their email. Bots, throwaway addresses and repeats are blocked, and you can see why.

The waitlist is the heart of a smoke test: the number of strangers who leave an email is how you validate demand for an idea before you build it.

Every number is a person.

  • A confirmation email goes out right after sign-up, from your own domain
  • Only confirmed emails count, in results and in referrals
  • Waiting and blocked sign-ups stay visible

Questions about waitlist

Where do confirmation emails come from?

From your own domain, connected once on a paid plan. On the free month, sign-ups are collected but not confirmed, and you can export them as a CSV.

What if someone never confirms?

They stay in the list as waiting, and don’t count toward results or referrals.

Can I turn protection off?

The basic checks are always on. The rest you can switch per experiment.
