Auto Responder: reply to people who fill in your form
Formbold can now email an automatic reply to whoever submitted your form. Available on Premium and Business.

People like to know their message arrived. Turn on Auto Responder in your form's Settings and Formbold sends a reply to the person who just submitted.
Your form needs an input with name="email", otherwise there's nowhere to send it. Keep the message short and set expectations, something like "We reply within one working day."
Turn on spam protection at the same time so you aren't writing back to bots. Auto Responder is part of the Premium and Business plans. More in Form Settings.
