PostTo
Turn any HTML form into email. No backend, no spam.
A form backend for developers and vibe-coded apps. One URL in your form action gets you email delivery, layered spam filtering, a submission dashboard, webhooks and CSV export. Hosted in Europe, encrypted at rest, free for 50 submissions a month. Most form services quietly bin anything their spam filter dislikes, so you never learn about the lead you lost. PostTo holds flagged submissions in the dashboard with the score and the reason, and you release them with one click.
Hey Product Hunt 👋
I'm Tor, and I built PostTo because I got tired of the same twenty minutes on every client site: SMTP or sendmail, SPF and DKIM, and chasing admin access to someone's Microsoft 365 tenant just to make a contact form send. Working out of Norway, where GDPR gets real attention, offloading it to a US form service wasn't an obvious answer either.
PostTo is one URL. You set action="https://postto.dev/api/v1/send/" on your existing form and it works, no JavaScript, no SDK, no markup changes. We handle validation, spam filtering, storage and delivery. If you're calling from a backend instead, there's a signed HMAC-SHA256 mode with a configurable replay window.
Two decisions I care about more than the rest. First, held, not deleted: every spam-flagged submission stays visible in your dashboard with its score and reason, one click from delivery. I'd rather show you a false positive than hide a real customer. Second, EU-hosted with encryption at rest on every plan, including Free — submission bodies are PII and should be treated that way whether or not you're paying me.
Free plan is 50 emails/month with the full dashboard and API, no card, no trial clock. Paid plans start at $9. Quota counts delivered emails only, so bots don't cost you anything.
I'd love feedback on the parts I'm least sure about: is the spam threshold tuning discoverable enough, and does the AI opt-in consent flow feel proportionate or annoying? Happy to answer anything in the comments.
