AT&T Mail
What AT&T Mail is
AT&T Mail is an email service for AT&T customers and people with supported legacy accounts. Eligible new users can register @currently.com or @att.net addresses; SBCGlobal, BellSouth, and Ameritech accounts are also supported. Users can read and manage mail in a browser at currently.com. AT&T lists Apple Mail, Outlook Mobile, and Yahoo Mail for supported iOS devices, and Gmail, Outlook Mobile, and Yahoo Mail for supported Android devices. For supported email domains, it provides IMAP and POP3 settings. AT&T recommends OAuth-capable apps; apps without OAuth require a 16-character secure mail key. That key can also support syncing account information such as calendars and contacts. Webmail allows images in message bodies, and a Photos folder collects images sent or received. A message can include up to 50 files, with a maximum total message size of 25MB. AT&T provides self-service setup, troubleshooting, security, password, and account recovery help, plus support videos. The listed Free plan costs nothing and includes 1TB of storage. Yahoo! Mail Plus is $5 a month, billed $5 per month, and lists 5 TB of storage and 500 email domains.
