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.
