+# 📣 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 Timeline
+
+| Carrier | Old Gateway Address | Status |
+|---|---|---|
+| Sprint | `@messaging.sprintpcs.com` | ❌ Shut down early 2022 |
+| Boost Mobile | `@sms.myboostmobile.com` | ❌ Shut down 2022 |
+| T-Mobile | `@tmomail.net` | ❌ Offline December 2024 |
+| AT&T | `@txt.att.net` / `@mms.att.net` | [Shut down June 17, 2025](https://www.att.com/support/article/wireless/KM1061254/) |
+| Cricket Wireless | `@sms.cricketwireless.net` | ❌ Shut down with AT&T |
+| Verizon | `@vtext.com` / `@vzwpix.com` | ⚠️ Unreliable - [phasing out by March 31, 2027](https://www.verizon.com/support/vtext-vzwpix-shutdown/) |
+
+## Why Did Carriers Shut Them Down?
+
+The free carrier gateways became major spam and phishing vectors (aka ["smishing"](https://www.ibm.com/think/topics/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 Else
+
+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 → [10-digit-phone]@txt.att.net
+```
+
+You just change the domain to your PagerTree address:
+
+```
+alerts@yourserver.com → [10-digit-phone]@your-domain.e2t.pagertree.com
+```
+
+## How to Set It Up (2 Minutes)
+
+1. **[Sign up for PagerTree](https://app.pagertree.com/signup)** - free 14-day trial, no credit card required.
+2. **Enable Email-to-SMS** - Available on Pro and Elite plans. [Contact support](mailto:support@pagertree.com) to enable.
+3. **Swap the domain** - Replace your old carrier gateway domain with your new PagerTree domain in the systems that are sending the emails.
+4. **Test it** - Send a test email to your PagerTree email-to-text domain and confirm the SMS notification arrives.
+
+Just like that, your existing setup works exactly as before!
