Hi Dan,

As I understand it, txt.att.net is a low-volume courtesy service not
intended for important communications. A paid service like Twilio can
handle production-grade SMS delivery.



I think ChatGPT agrees with you:

txt.att.net is a domain owned by AT&T, a large American telecommunications company. It is typically used to send and receive text messages, and it is generally considered a reliable resource for this purpose. However, as with any online service, it is possible for issues to arise, such as delays in delivery or errors in sending messages. It is also worth noting that txt.att.net is a free service, so it might not have the same level of security or reliability as a paid service. If you have any specific concerns or experience issues with txt.att.net, it's best to contact AT&T customer service for assistance.

;-)

Warm regards,
