§ Contact-form backend / v1

Forms that just send you the message.

Point any HTML form at one URL. We receive the submission, filter the spam, and email it to you, DKIM-signed so it actually lands. No server, no SMTP, no backend code.

How it works01

Live in three steps.

The whole integration is one URL. No library, no build step, no server on your side.

01

CREATE

Create a form

Sign up free and get a unique endpoint URL. Takes about ten seconds, with no config and no DNS.

forms.vastrox.com/f/8kd2p
02

PASTE

Point your form at it

Set your form’s action to the endpoint and use method="POST". Every named field is captured.

<form action="…"
  method="POST">
03

RECEIVE

Get the message

Each submission is emailed to you, stored in your inbox, spam-filtered, and can fire a webhook.

Everything you need02

A real form backend, not just an email relay.

All of this is on the free plan. Built to be premium from the first submission.

[ DELIVERABILITY ]

Email notifications

Every submission arrives as a clean, formatted email you can reply to directly.

[ SPAM ]

Spam protection

Honeypot, timing traps, content heuristics, and disposable-email detection catch bots before they reach you.

[ CAPTCHA ]

Captcha when you want it

Turn on Cloudflare Turnstile per form for a friction-light challenge. Off by default.

[ UPLOADS ]

File uploads

Accept attachments with multipart/form-data. Type and size validated, delivered with the email.

[ WEBHOOKS ]

Webhooks

Forward each submission as JSON to Zapier, Make, Slack, Discord, or your own API. SSRF-guarded.

[ ROUTING ]

Redirect & success pages

Send visitors to your own thank-you page, or show a custom success message. Per form.

[ INBOX ]

Submission inbox

Everything stored and searchable in your dashboard, so nothing is lost. Export to CSV.

[ SECURITY ]

Domain locking

Restrict a form to your own domain so nobody can hijack your endpoint from another site.

[ SIGNED · DELIVERABLE-BY-DEFAULT ]

Notifications that actually reach the inbox.

Every email we send on your behalf is DKIM-signed and SPF-aligned from vastrox.com infrastructure. That is the single biggest reason form mail lands in the inbox instead of the spam folder, and you configure nothing.
