SMS booking agent with lead follow-ups
Customers text a Twilio number; an AI agent checks Cal.com availability and books, reschedules or cancels. A daily job finds interested leads who never booked and sends a personalised follow-up, logging each one to avoid over-messaging.
Tool names link to each official site (opens in a new tab). Links marked “aff” are affiliate links. Disclosure
