Who it's for

For indie developers

Ship the update, send the email, get back to building.

Email your users about what's new — without paying per subscriber or learning a marketing platform. Built for a team of one.

Sound familiar?

  • You're a team of one — no hours to spend wiring up audiences and automations.
  • The list is an asset you built by hand. Paying more just to keep it is backwards.
  • You want a form to drop into your site and a changelog email you can send in five minutes.

How day3 fits

Forms you can embed anywhere

Hosted page, iframe, popup, or raw HTML — paste it into your site, bio, or docs, with double opt-in on by default.

Billed on sends, not your list

The audience you built stays free to keep — you pay only when you actually send.

AI drafting when you're stuck

Draft a campaign or rewrite a line with Claude — included on every paid plan.

No upsell path

No funnels, no automation, no sales call — just the email and who gets it.

Questions

Is day3 good for indie hackers?
Yes. It's deliberately minimal, priced by sends so the list grows free, and ships embeddable forms plus AI drafting on every paid plan. Built for solo founders, not marketing teams.
Can I add a signup form to my own site?
Yes. Use a hosted page, an auto-resizing iframe, a JS popup, or a plain HTML form that POSTs to day3 — whichever fits your stack.
