How to write the format of short message?

I don't know if you are talking about personal information or information sent in the name of the company.

If it is a short message sent by a company through a short message platform, there are generally two sending formats:

Marketing category: signature+SMS content+unsubscribe information

Industry category: signature+SMS content

Because I don't know my specific needs, and I'm worried about answering irrelevant questions, maybe I can further communicate with Babu SMS, hoping to help you.
