Email guesser result all are valid

Hello I often get results in the email guesser where all the email combinations are valid. What does that mean?? By the way I love the email guesser!!!!
Yes, I get that too and honestly we do not have an exact answer for what that means or why that happens. I would not use the data as credible and just operate as though the email guesser does not work for that particular contact.

In my own personal use, I get that about 1 or 2 times out of every ten attempts. So I see it too but it does not happen on most attempts.
