The AT&T Email-to-Text shutdown took effect on June 17, 2025. It has created a critical need for a reliable, secure, and modern alternative to make sure critical messages still reach the right people instantly.
Many companies have reached out to us looking for an alternative, so we’d like to share the most important details with you.
According to AT&T, the Email-to-Text service officially ended on June 17, 2025:

What does the end of AT&T Email-to-Text Messages mean for you?
This change means you can no longer send text messages by email to AT&T subscribers using addresses like number@txt.att.net or number@mms.att.net.
As a result, you need a new way to send alerts and urgent notifications and keep teams in IT, manufacturing, healthcare, and other industries informed. You still want a simple way to send alerts, and the switch should be as easy and seamless as possible so your existing alerting process keeps running.
Can I simply switch to another email-to-text gateway?
Technically, yes. But before switching to another carrier gateway, it’s worth asking whether email-to-text is still the right solution for critical alerts. Most email-to-text gateways simply replace one email-to-SMS service with another. They don’t provide acknowledgements, automatic escalations, delivery tracking, or on-call routing. If reliable incident response is important to your business, this is a good opportunity to move beyond email-to-text instead of replacing it.
What should you do now?
Now is a good time to ask yourself whether Email to Text was ever enough for critical alerts. Sending alerts from your systems and tools to mobile phones is only one part of effective alerting. It leaves a lot of important questions unanswered.
- Was the message actually delivered?
- Did the right person see it?
- Did they respond right away?
- What action did they take?
- What happens if they don’t respond?
Email to Text is based on hope. You send the alert, but you don’t know if it reached the right person, if they saw it, or if they actually responded.
Now is the perfect opportunity to change that and make sure your alerts not only reach the right person but also get a response.
This is where SIGNL4 comes in. It bridges the gap between your systems and the people who need to act.
What does SIGNL4 offer as an alternative?
The most important thing first: Getting started with SIGNL4 is quick and easy.
SIGNL4 doesn’t just deliver alerts in real time. It also makes sure someone responds. You always know who accepted the alert, when they accepted it, and who is taking care of the issue.
Here’s what you get with the modern email-to-text replacement SIGNL4.
Fast setup in just five minutes
SIGNL4’s Email to Text feature is ready to use out of the box. Just add and verify your users’ phone numbers. Sending an email instantly triggers SMS alerts and, for users with the mobile app installed, push notifications.
Modern mobile alerting instead of outdated Email to Text gateways
Reach your teams wherever they are with push notifications, SMS, voice calls, and email. This gives you the best possible chance of reaching the right person.
Actionable alerts
The SMS character limit often means critical information gets left out. SIGNL4 alerts don’t have that limitation. They can include links, images, videos, voice messages, and all the context responders need to take action right away.
Acknowledgment and accountability
Acknowledge alerts with a single tap and see in real time who accepted the alert and is responding.
Built in team chat
Every alert comes with its own built in team chat. Team members can communicate, ask questions, share updates, and get help from others without switching to another app. Everyone stays on the same page until the issue is resolved.
Easy integration
SIGNL4 fits seamlessly into your existing workflows with out of the box integrations for Microsoft Teams, Azure Monitor, Splunk, and many more. It also supports REST APIs and webhooks for custom integrations.
Team routing and on call scheduling
Unlike Email to sms services from AT&T or other carriers, SIGNL4 supports intelligent routing based on who is on duty. You can easily configure on call schedules, shifts, and escalation paths.
Secure and auditable
SIGNL4 offers end to end encryption, role based access control, and a detailed audit trail, making it ideal for organizations with strict compliance requirements.
