To verify your email, you will need to go into the email account attached to your Mobcrush username. From there you will find an email from email@example.com regarding account activation. Inside that email is a big blue button you'll want to click on, and then that's it!
If you don't see the email, please check the junk/spam folder to see if it landed in there, and if not please add firstname.lastname@example.org to your email whitelist and request the verification email again from inside the Mobcrush app or on the Mobcrush website.
If after all of that you still aren't receiving your email, please submit a support ticket with your Mobcrush username, email that you used to create the account, and the email that should be on your Mobcrush account.
