Create your form endpoint

We verify the destination before accepting submissions.

Use any label you like. It does not need to be unique.

Only used to verify and deliver your submissions. The free monthly allowance is per verified email — forms sharing an inbox share one quota.

We create your endpoint immediately. Confirm the inbox before it can deliver.

What you receive
<form action="https://api.conform.centrst.com/f/cfm_7K4P9X2M8RWD3JNH" method="post">
How it works

Three steps, then conForm disappears into the plumbing.

  1. 01Name and verify

    Tell us what to call the form and which inbox owns it. The route stays inactive until that inbox confirms.

  2. 02Paste the endpoint

    Use the endpoint as the action on any HTML form. There is no client library and no framework requirement.

  3. 03Receive the submission

    conForm forwards the fields to the verified inbox as text or, optionally, as a JSON file. Every form delivering to the same inbox shares one monthly allowance.

conForm+

Higher limits.A person to email.

Start with managed delivery for free, then upgrade when your forms grow. conForm+ raises hosted limits, adds email support from a person who runs the service, and tells you about the submissions that didn’t reach your inbox — counts and delivery status, never field contents.

  • More deliveriesHigher monthly limits for every form delivering to your inbox.
  • Email supportSetup, delivery questions, and the occasional strange form — answered by a person.
  • Delivery insightCounts, delivery status, and abuse resiliency for what didn’t arrive. Never field contents.
Start free, upgrade later

Your inbox is the system of record.

Hosted conForm sends submissions directly to your verified inbox instead of building a second readable inbox or CRM. Centrst and the delivery provider process the contents long enough to deliver that email — nothing is stored afterwards. For zero Centrst access, run the open-source Worker yourself.

Hosted FreeOne managed monthly allowance per verified email, HTTPS in transit, and no separate conForm submission CRM.
Self-hosted foreverDeploy the same Worker in your Cloudflare account. No Centrst account, route record, or data path.
