Sending different autoresponder templates based on result from form validation

2- I want to send an email to the customers after the validation of the form and tell them (if the field are not the same to redo it) (if the field are the same to tell them thank you).

Hi,

With JotForm it is easy to setup several different email templates and send different once based on the conditions you set.

Now what I would suggest is taking a look at the following guides:

Creating a Form Autoresponder

How to send to a specific email address based on a selection?

In case you have any further questions or need any assistance along the way do let us know about it and we would be happy to help.

Best Regards,
Ben
