๐ฃ Email-to-SMS Replacement: Carrier Gateways Are Gone (AT&T, T-Mobile, Verizon)
AT&T, T-Mobile, and Verizon have all shut down their free email-to-text gateways. These gateways powered what most teams think of as "email-to-SMS" - sending an email to a phone number to trigger a text message. If your scripts, monitoring systems, or alerting tools are still pointing at @txt.att.net, @tmomail.net, or @vtext.com - your alerts are silently failing.
PagerTree is the drop-in replacement. Just replace the domain. Everything else stays the same. PagerTree uses verified messaging infrastructure (A2P 10DLC), ensuring messages are delivered reliably instead of silently dropped like legacy gateways.
Carrier Gateways Shutdown Timelineโ

| Cricket Wireless | @sms.cricketwireless.net | โ Shut down with AT&T |
| Verizon | @vtext.com / @vzwpix.com | โ ๏ธ Unreliable - phasing out by March 31, 2027 |
Why Did Carriers Shut Them Down?โ
The free carrier gateways became major spam and phishing vectors (aka "smishing"), and carriers retired them rather than maintain them under modern A2P messaging regulations. They're not coming back.
The Fix: Replace the Domain, Keep Everything Elseโ
PagerTree gives your account a unique email domain to send alert emails to. You send an email to [10-digit-phone]@your-domain.e2t.pagertree.com (must be a verified phone number in PagerTree) and PagerTree sends an SMS to your phone. That's it.
If you had something like this working before:
alerts@yourserver.com โ [10-digit-phone]@txt.att.net
You just change the domain to your PagerTree address:
alerts@yourserver.com โ [10-digit-phone]@your-domain.e2t.pagertree.com
