Use Custom Regular expressions for a fom validation

Hey @pramilaniroshan – Thanks for reaching out!

To validate an email address with WPForms, you can create an Allowlist or Denylist. Then, you can add rules, similar to regex, to define which email addresses will be able to submit your form. For more details, please see our guide Creating an Email Address Allowlist or Denylist, especially this section: Adding Email Denylist or Allowlist Rules.

Another option would be to use an input mask within a Single Line Text field, and you can see our guide on how to create and add a custom input mask to that field.

I hope this helps!
