When sending TopView notifications via a carrier’s email-to-text gateway, you may see notifications come from many different numbers. In general, TopView has no control over numbers used by carriers to send text messages when sending messages through the carrier’s email-to-text gateway.

If AT&T is your carrier, using the email address “[number]@mms.att.net”, instead of the typical text gateway address (“[number]@txt.att.net”), will send from a consistent address.

See this post on AT&T’s forum for more information.
