When a call goes to voicemail, most people don't leave a message. They hang up and call the next business on the list. For a plumber, dentist, or med spa, that's a lost booking you never even knew about.
Missed-call text back closes that gap. As soon as a call goes unanswered, the caller gets a text from your business number asking how you can help, with a link to book or a promise of a quick call back.
