Trying a reverse email lookup

My mother met a new guy online the other day, but she couldn’t get hold of him without being a part of some website. She eventually got his details from an email that he had sent her previously. They weren’t directly on the mail itself, but after trying a Reverse Email Lookup, she was able to get hold of him on the phone and they have since hit it off a whole better than just sending the slow emails. Needless to say, she now has a date set up with him and she looks very excited that she is going to meet him for the first time.
