Autoresponder defined.
An autoresponder is an automatic reply email sent to the person who submitted a form, confirming their message arrived and telling them what happens next, without anyone having to write it.
How an autoresponder works
When someone fills in a contact form they get no receipt by default, so they are left wondering whether it went through at all. An autoresponder closes that gap: the moment a valid submission arrives, the system sends a short confirmation email back to the address the visitor entered. It reassures them the message landed, sets expectations for when you will reply, and can carry a next step like a booking link or a support article.
The mechanics are worth understanding, because the mail goes to a stranger's inbox and has to survive spam filtering. That means it must be sent from an address your service is authenticated to send as, with a sensible Reply-To pointing back at you.
FormWire ships this as its auto-responder: enable it on a form, set the subject and body once, and every submitter gets an immediate, deliverable acknowledgement while you get the notification.
What an autoresponder does for you.
Confirms receipt
The submitter learns their message actually arrived, so they do not resend it or assume the form is broken.
Sets expectations
A line about when you typically reply buys you time and cuts the anxious follow-up. Add a booking or help link for the next step.
Stays deliverable
Sent from an authenticated address with Reply-To set to you, so the acknowledgement reaches the inbox instead of the spam folder.

They travel in opposite directions. The notification goes to you, the site owner, telling you a submission came in. The autoresponder goes to the visitor, confirming their message was received. Most form backends send both from a single submission, so you are alerted and they are acknowledged at once.
It can, if it is sent carelessly. Because it goes to an address the sender does not own, it has to be sent from an authenticated domain with proper SPF, DKIM and DMARC alignment. Deliverability is the whole game for automated mail, and a well-configured form backend handles this so your acknowledgements arrive.
Why deliverability decides whether it lands →Yes, if you set Reply-To to a real address you monitor. The message is sent from the service's authenticated address, but Reply-To routes any answer back to you, so a visitor who hits reply on the confirmation reaches a human rather than a no-reply void.
Yes. FormWire's auto-responder is a per-form toggle: write the subject and body once, and it emails every submitter a confirmation using the email field they entered. It runs over the same authenticated delivery as your notifications.
