AT&T Is Ending Email to SMS Services

AT&T Email Messaging Gateway (EMG) Discontinued

Big changes are coming for businesses that rely on email to text and text to email services. As of June 17, 2025, AT&T will be discontinuing its Email Messaging Gateway (EMG), officially putting an end to its long-running email to SMS (SMS and MMS) functionality. If your organization uses these services to communicate with customers or staff, now’s the time to explore new options.

What’s Changing at AT&T?

AT&T and its subsidiaries, including Cricket and FirstNet, are shutting down the ability to send or receive text messages via email. This affects anyone using the following email formats to send messages to AT&T mobile subscribers:

• mobilenumber@txt.att.net
• mobilenumber@mms.att.net
• mobilenumber@txt.firstnet-mail.com
• mobilenumber@mms.firstnet-mail.com
• mobilenumber@txt.cricket.net
• mobilenumber@mms.cricket.net

After June 17, 2025, any messages sent using these domains will fail and won’t be delivered.
