Mystery for you: We had one form submission of a gmail address that was subaddressed to our company using the +suffix@gmail.com construction.

But when I try to test our forms with similar email construction, I get an error that says I need to use a valid email address.

How can I permanently enable subaddressed emails? I’ve tested required vs not required form fields. I can’t find any documentation about subaddressed emails.

Help!

@LFatolitis Typically it’s possible to have [jennifer+Test@aptitude8.com](mailto:jennifer+Test@aptitude8.com) as a form submission, if you’re seeing in on one form and not another, you might check if they are using the same email field and then check the rules for that property to see if there are any restrictions:

Hey LFatolitis, that’s a tricky one! Have you checked your form’s email validation settings? Sometimes custom regex patterns can accidentally block valid formats like subaddressed emails. Might be worth a look!
