Everything your form needs
Mailiy runs your form backend: delivery, spam protection and retention. All you do is answer.
Submissions at a glance
Every message lands in your inbox and, if you like, AES-256 encrypted in the dashboard, with CSV export.
Deliveries per month
See at a glance how many messages arrive and how much spam was blocked.
Multiple recipients
Up to five confirmed addresses per form. Replies go straight to the sender.
Deletion by design
Choose per form how long submissions are kept. After that they are gone for good.
Spam protection without puzzles
Honeypot, rate limits and allowed domains. If that is not enough, switch on ALTCHA: it works in the browser, with no picture puzzles and no third parties.
Live in three steps
No server, no SMTP, no backend code.

Frequently asked questions
Is the key secret?
No. The key is public and belongs in your source code. It only allows submitting to your form. Use allowed domains to limit which websites can do so.
Do I need a data processing agreement?
Yes. Mailiy processes personal data on your behalf, so you need a DPA under GDPR Art. 28. You conclude it with a checkbox when you sign up; the text is under “DPA”.
Where are the servers?
On a Linux server in a data centre in the EU. Mailiy uses no external CDNs, fonts or analytics.
What happens when the limit is reached?
Further submissions that month are rejected with a clear error message. The quota resets at the start of each month.
Does it work with React, Astro or WordPress?
Yes. Mailiy is a plain HTTP endpoint. Anything that can submit a form or call fetch() works.
Need a custom solution?
Your own sender domain, self-hosting or high volumes: we'll find a setup that fits your privacy concept.
