I am creating a subscriber form and I have seen I can specify an Initial Confirmation Page URL on my site. I noticed if I do not complete the form fields that it takes me to an Invalid Email Address page located on the createsend.com domain.
I would like to know if I can have a page on my site for this scenario rather than taking the user to the createsend.com URL?
Any advice much appreciated.
It isn't possible to replace that error page, but what you can do is add on your own custom validation to your form using a script like this one so that you're checking to see if the email address is valid before submitting the information to us, that way the default error is never shown.
