Hi folks,

I apologize if this is a strange question for this forum beforehand.

I recently set up a contact form for a client and a user has entered their email address incorrectly into the form and now my client can't get in touch with the enquirer and may lose out in a job as a result.

I am now going to put a confirm email field into the form to at least lessen the possibility of this happening again(hoping people don't just copy and paste).

My question is this. Is there an easy way my client can find out the enquirers correct email address from the wrong email address, considering it must be a close match to the correct address, and from the area the enquirer lives that was given in the form?

Thank you
