Att email differs from other mail because in Att email we can add a sub-account to share files and important data. And the interesting thing is that we can Add up to 20 sub-account email addresses, and use 10 sub-accounts at a single time. As we know, email accounts are used to share files and data but some minor things make it different from one another. We are here for the email application, so I am telling you about Att email and you can also visit the Att email settings website for more information. Contact our experts for Att support and settings.
