Hi, please make sure you've checked your spam folder as system mail may end up there. I don't know if your mail provider has us in their block list, but you may also add support@nabistudios.com and no-reply@nabistudios.com to your contacts there just to make sure email goes through.
If you still don't receive verification mail, please contact us at support@nabistudios.com using the email linked to your account to have it verified manually - though at that point you may consider switching your linked email as it likely means you won't be able to receive password recovery (if you ever need one in future) as well.
