You may be in the test phase of checking all is working fine with your new webform(s) but you are finding that when using your email address multiple times that the subsequent test sign ups are not coming in as new contacts...?

A: Our webforms only allow a once-only sign up per unique email address, so if you're testing your form just ensure that you use a different email address each time!

Hint: if you want to link your webform to a group, just link up with an automated campaign within which you have an action to add to group.
