Webflow.

Webflow forms can post anywhere. Set the action, keep the field names, and Webflow’s built-in success and error blocks keep working.

Form settings

Select the form block, open the settings panel and set Action to your submit URL and Method to POST. In the field settings, give every field the name you want to see in the mail.

Settings

Action: https://mailan.email/api/submit/YOUR-ACCESS-KEY Method: POST Field names: name · email · message Hidden field: botcheck (honeypot, leave empty) Hidden field: redirect (optional, your own thank-you page)

Keep Webflow’s success state

Add this in Project settings → Custom code → Before . It submits via AJAX and shows Webflow’s own success block instead of leaving the page.

HTML

<script src="https://mailan.email/client/v1/script.js" defer></script> <script> document.addEventListener("mailan:success", (event) => { const wrapper = event.target.closest(".w-form"); if (!wrapper) return; event.target.style.display = "none"; const done = wrapper.querySelector(".w-form-done"); if (done) done.style.display = "block"; }); </script>
