Identify yourself: If your identity appears known, there’s a better chance your message will be received.
Offer an opt-out: The more upfront you are about unsubscribing, the likelier a recipient will not block or report you.
Optimize message length: If your SMS exceeds 160 characters, there’s a chance the carrier could split it into multiple messages.
Encourage replies: By requesting responses other than an opt-out, your message provides a positive signal.
Limit sending frequency: Sending too many messages from the same number during a specific period could result in a violation.
Use branded URLs: use a full URL like this @redoxygen.com or a branded shortened URL like @red.xgn
