Looks like AT&T will not be supporting email to text. I'm getting these emails after Two Tone detect sends out pages.
Hi, it’s AT&T. On 6/17/2025, we’ll stop supporting email-to-text messages. That means you won’t be able to send a text message to an AT&T customer from an email address. You can still get in touch with AT&T customers using SMS (text), MMS, and standard email services. For more info, go to
