One message, then a person
The first text names the business, says the call was missed, and gives a link to book or a question they can answer. It does not pitch a package. It does not send three more texts that afternoon.
If they reply, the automation stops and a person takes it. If they book, it stops. If they say stop, it stops.
Send it from a number they can call
The text should come from the number that just rang, or from the number printed on the site. A strange short code makes the message look like spam, and the lead does not come back.
Test it on a real phone before the client is told it is on. Check the wording, the link, and that a reply lands in the conversation.
Put the result on the pipeline
A missed call that only lives in the phone log is easy to ignore. The text-back should create or update the contact and leave a note on the opportunity so the next person sees that the call was missed and the text went out.
That is the whole job of this workflow. Do not hang a newsletter on it.
