Hi there, @AeroConsultants 
Many thanks for the feedback!
Unfortunately, the validation of the Email and Phone fields isn’t supported in our app now. The request for the email validation is already on the Wishlist - Email address validation.
As for the phone validation, I’ve added this request to the Wishlist on your behalf - Phone number validation.
We’ll keep tabs on these ideas and try to consider them, especially if more users upvote them
