Can Jotfform send automatic replies to registerants?

Hi,

Is there a way for Jotform to send an automatic reply to everyone who registers to our event using Jotform?

Thanks,
Esther

Yes, an email auto-responder is automatically added to your form as soon as an email field is added to it. 

You could also manually add the email auto-responder by following this guide: Setting-Up-an-Autoresponder-Email
