Not getting activation email

Hi,

   Im the IT Manager of my company and im having issues to get the activation email on a new account, whenever i request the code the code never gets to the account email, i already checked the spam folder but its not there, altho i created an alias on that email and the activation msg does arrive, so im thinking the email should have some sort of block on zoom servers or something that is preventing it from sending the activation email, but i tried to submit a ticket and the system closes my ticket automatically cause im not a pro user but a free one
