Frequently Asked Questions

Everything you need to know about our HTML form backend and email API.

What is a form backend API and why do I need one?
Static websites (HTML, Jamstack, GitHub Pages) have no server to process form data. GoSecureServer-Email acts as your form backend — it receives submissions and emails them to you instantly, with zero server or backend code on your end.
Is this really free? Do I need to create an account?
No account or signup required. Simply set your form's action attribute to our endpoint and start receiving emails immediately.
Does this work with React, Vue, Next.js, or other JavaScript frameworks?
Yes. Plain HTML forms work without any JavaScript. For React, Vue, Next.js, or any JS framework, use fetch() or axios to POST JSON to the same endpoint and receive JSON responses for full control over success/error UI states.
Will form submission emails go to spam?
Emails are sent with full DKIM, SPF, and DMARC alignment using Postfix and OpenDKIM. PTR/rDNS is properly configured for maximum deliverability — emails reach inboxes, not spam folders.
What alternatives does this replace?
GoSecureServer-Email is a free alternative to Formspree, Netlify Forms, Getform, FormSubmit, and EmailJS. No account required, unlimited custom fields supported.
How do I protect my form from spam bots?
Add a hidden honeypot field named hp_email to your form, hidden with CSS (display:none). Bots fill it in automatically which our API detects and silently discards. Real users never see it.
