About e-mail sign up problem!

I kown These are two different place
#1 is Mappily
#2 is https://forum.mappily.info/

I use e-mail for #1 sing up , I receive Mappily Signup request soon
but I use the same e-mail for #2 sign up, I never receive any request
Why?

Due to this reason, I use my another e-mail for #2 sign up , I receive Signup request
I use another e-mail to post this thing in this #2

Hi, yes, this is a forum which has a separate user setup.

If the email address that doesnt work a gmail account by any chance? I think gmail might be rejecting our mails if so.
