For system administrators looking to replace AT&T’s discontinued email-to-text gateway, EmailToVoice.Net provides an immediate, compatible replacement with enhanced capabilities for your critical notification infrastructure.

Replacing AT&T’s Email-to-Text with EmailToVoice.Net

If you’re managing systems that depend on AT&T’s email-to-text service for alerts or notifications, you need a migration plan now. AT&T is terminating its email-to-text and text-to-email services on June 17, 2025, requiring immediate action for any operational systems utilizing the @txt.att.net or @mms.att.net gateways.

Technical Impact of AT&T’s Discontinuation

After June 17, 2025, these endpoints will stop functioning:

  • phonenumber@txt.att.net (SMS gateway)
  • phonenumber@mms.att.net (MMS gateway)
  • Any inbound text-to-email functionality

If your monitoring systems, alert infrastructure, or automated workflows depend on these gateways, they will fail without appropriate reconfiguration.

    • Any system capable of SMTP output
  5. Logging & Troubleshooting – Real-time message tracking and detailed delivery status for system administrators.
  6. Customer Portal – create escalation lists for voice calls, delivery windows, message parsing, and much more

Implementation Guide

Converting your systems from AT&T’s email-to-text gateway to EmailToVoice.Net requires minimal changes to existing configurations:

Basic Configuration:

  • Initial Setup:
    • Register for EmailToVoice.Net (free trial available)
    • Provide your sending email domain or specific email addresses. (Recipient phone numbers do not need to be preregistered)
  • SMS Configuration:
    • Replace: phonenumber@txt.att.net
    • With: phonenumber@sms.message-service.org
    • Example: 5555555555@sms.message-service.org
    • Maintain your existing email body format
  • Voice Call Configuration (New Capability):
    • Use: phonenumber@tts.message-service.org
    • Example: 5555555555@tts.message-service.org
    • Email body becomes spoken message content
  • Rich Communication SMS 
    • Use: phonenumber@linknsms.message-service.org
    • Example: 5555555555@linknsms.message-service.org
    • Email body becomes a hosted web page with the URL embedded in the SMS

Advanced Implementations:

  • Lists – Use predefined distribution lists
  • Managed Delivery – Set time windows for message transmission
  • Custom Response Handling – Configure message reply destinations to Agentic workflow processing
  • Parsing Content – Specify message start/end points for translating only relevant alert data

Technical Use Cases

EmailToVoice.Net has been implemented in critical infrastructure environments, including:

  • Server/network monitoring alert escalation
  • Industrial control system notifications
  • API failure notifications for DevOps teams
  • On-call rotation management
  • Critical infrastructure status alerting
  • AI Agentic workflow communications

Migration Timeline Recommendation

Given the June 17, 2025 cutoff, a phased implementation approach is advised:

  1. Immediate: Register and test the EmailToVoice.Net platform with sample alerts
  2. 30-60 days pre-cutoff: Switch primary alert routing to EmailToVoice.Net
  3. Post-migration: Utilize enhanced capabilities like voice calls and Rich Content password-protected SMS messages for critical alerts

Transitioning to EmailToVoice.Net now ensures system continuity while providing significant technical improvements over the legacy AT&T gateway service.
