How to add email address field in the recipient field?

what a bad news :(

and if i add {emailAddress} on the recipient field?

Please note that it is not possible to use field tags in the email notification as the email recipients. You may instead setup an autoresponder to choose the field to send an email.

Alternatively, you may setup a condition on the form to change the email recipients with the field tags.

However, please note that the email shall only be sent only when the rules in the condition are passed.

Thanks!
