<div style="margin-top:0;margin-bottom:0;">FWIW, AT&T does not suggest using the txt.att.net email for anything critical. In a previous role I handled public safety CAD, and AT&T (and Verizon, if I remember correctly) made it very clear that if you want to
be able to send anything other than a miniscule volume of texts through the email-to-SMS gateway, you would need to pay for their enterprise messaging service.

<div style="margin-top:0;margin-bottom:0;">If the public safety agency/agencies in question subscribe to the FirstNet service, they should be able to reach out to their principal consultant (account team) and get a good resolution.

<p style="margin: 0in; font-size: 11pt; font-family: "Calibri", sans-serif;">Know this is a longshot, any chance anyone from the txt.att.net domain might be able to help us with what we believe is a blacklist block or possibly an outage?</p>
<p style="margin: 0in; font-size: 11pt; font-family: "Calibri", sans-serif;">We deal with 911 cad dispatching and is affecting first responders so looking to see if there is a faster way to resolution.</p>
