Your past customers already trust your crew, and when the season turns they need the work again. The trouble is nobody has time to text the whole list, so that repeat business slips. This automation reaches all of them in one run. It sends each past customer a personalized seasonal SMS, segmented by service: an HVAC customer gets an AC tune-up message, a landscaping customer gets a spring cleanup pitch, a pest control customer gets a barrier treatment offer.

AI writes each message using the customer's name, their service history, and the current season. Sends go out in rate-limited batches so you stay inside Twilio's throughput limits. Anyone who already got this campaign is skipped automatically. Every send is logged, and a no-response flag builds you a list of who to chase with a follow-up.

Setup takes about 35 minutes. You bring a past-customer spreadsheet with job types and phone numbers, connect Twilio and OpenAI, and run the campaign with one click. It can also run itself on a spring and fall schedule if you want it on autopilot.
