You are not receiving either your Studio verification email or Studio invitations and notifications.
Your emails are likely being forwarded to your junk/spam folder or being blocked by your network administrator.
Assuming you’ve created a Studio account using Bluebeam Revu, or with your iPad using Revu or Vu for iPad, an account validation email was sent to you from firstname.lastname@example.org. Check your junk/spam folder for the validation email if you haven’t received a message in your inbox. If you still can’t find the validation email, or if you’ve managed to verify your account but are still not receiving Studio emails, you’ll need to contact your IT department to unblock the messages.
If your department is using the SPF Record (Sender Policy Framework) to check authorized email senders, they will need to add the following IP addresses to the list of authorized senders:
Once this has been done, you’ll be able to validate your account and continue receiving emails in Studio.
