Can’t create account

Hello.

This is my problem. I want to create account at my Helpdesk home menu and after I fill my account details I hit the button Creat Account button and this message appear "Thank you, please check your inbox at [email protected]". But when I check my inbox at [email protected], the message from Maian Support / Helpdesk didn’t come in. What happen and how to solve it? I hope you can give me the best answer.

Thank you.
