Auto-responder

Send a confirmation email back to the person who submitted your form. Available on the Pro plan.

Setting it up

Open your form's settings and go to the Integrations tab.
Scroll to Auto-responder and flip the toggle on.
Fill in the Subject and Message. Optionally set a display name in From name.
Click Save.

Personalizing the email

Use {{fieldname}} in your subject or message to insert whatever the submitter typed in that field. If your form has fields named name, email, and message, you can write:

Subject: Thanks {{name}}, we got your message
Body:
Hi {{name}},

Thanks for getting in touch about "{{message}}". We'll reply within 24 hours.

— The team

The placeholder uses the field's name attribute (what you wrote in the Name column on the Fields tab), not the visible label. If a field with that name doesn't exist on the form — or the submitter left an optional field blank — the placeholder renders as empty string. The email will never contain raw {{...}} mustaches.

Where the recipient address comes from

We pull the submitter's email from the form data. We check, in order:

A field named email, _replyto, or replyto (case-insensitive)
Any other field whose value looks like a valid email address (used as a fallback)

If no valid address is found, no auto-responder is sent — the submission still goes through and reaches your inbox.

When the auto-responder does NOT fire

Several safety rails prevent abuse and reply loops:

Spam-flagged submissions. If our spam heuristics flag the submission, no auto-responder is sent — even if everything else is configured.
No-reply addresses. We skip addresses like noreply@, no-reply@, donotreply@, postmaster@, mailer-daemon@, bounce@, and abuse@.
Rate limits. The same recipient receives at most one auto-responder per form per hour. Each form is also capped at 500 auto-responder sends per day to defend against bulk-abuse.

Reply-To and From

The email's Reply-To is set to your account email, so when the submitter hits Reply, the message goes to you, not into a black hole. The From address is always our sending domain — you can't override it (this is what makes deliverability work). You can, however, set a display name like Acme Support in the From name field.

Disabling temporarily

Toggle the auto-responder off in your form settings. The subject and message you saved stay in the database — flipping it back on later restores everything.
