How to whitelist our Email to Text notifications

I don't think we can do short code since our notifications are emails;

unless I don't understand short code.

Also, t-mobile has not flagged these same email-to-text messages for 12

years, why all of a sudden is my issue?

the emails start with "notification@" so I don't think that is the issue.

And perhaps I don't understand, I went to the t-mobile user forum and found

others with the same email-to-text issue and the resolution was having

t-mobile intervene somehow and fix it (whitelisting seemed to be how

t-mobile fixed it).

Any other suggestions?

We're you able to test changing the email address?

Hi, I have this exact same issue, except we are using a monitoring service that sends us email-to-SMS alerts.  Non-T-Mobile devices are able to receive those texts, so we know the issue isn't the monitoring service.  The email we use to send out those alerts is "alerts@<domain>.com", which we cannot change.  When there are events to be alerted on, each user registered to receive those alerts can sometimes get upwards of 20-30 in an hour.  Due to budgetary restraints, we cannot change over to using short code.

Are our T-Mobile users simply out of luck?  What else can be done to make sure that they receive the text alerts?

Seriously, this is driving us nuts. We have to send out the texts with the address our service uses, which is noreply@cteams.com. It is required for everyone to opt in for these services. Sometimes the message goes through to some users and sometimes it goes through to other users, sometimes it goes through to all. IT’S RANDOM! We also have messages that contain links to RSVP for events - the length requires it be split up into two messages. 1/2 goes through but 2/2 does not. There has got to be some kind of fix; this is ludicrous. Surely you understand that we are becoming increasingly reliant upon this traffic for communication.
