What does Pending Verification mean in the Email Control Center?
To ensure our email services aren't being used to traffic spam-related advertisements, we need to perform basic audits of the email accounts when they are created before they can be activated.
Due to the the number of email accounts being created at one time, this process can take up to 72 hours.
When validated, the new addresses are approved and activated. Once your account goes through this process, any additional email addresses you create are likely to be approved automatically.
