Has anyone experienced issues with text alerts being blocked by T-Mobile mailing server as Spam due to its special sender's address?
This issue isn't happening for Verizon / Affiliates & ATT / Affiliates.
T-Mobile shared the link (https://www.t-mobile.com/support/plans-features/consumer-versus-non-consumer-text-messaging?utm_sour... that talks about the way they expect alerts to be delivered.
Any Case study that can help get this resolved?
