Use AI to draft yearly maintenance reminder letters for past customers in 2 minutes instead of 30.
1. Open ChatGPT or Claude and tell it you're a plumber who wants to send maintenance reminders to past customers. Give it the type of job you did (like water heater service, drain cleaning, or annual boiler checks) and how long ago you did it. 2. Ask AI to write a friendly reminder message that explains why the customer should schedule a follow-up, mentions the original service date, and includes a call-to-action to book. You can specify the tone — professional, casual, or somewhere in between. 3. Review the message and tweak any details like your contact info, pricing mentions, or seasonal tips. Copy the final version. 4. Paste it into your email, text message app, or even print it as a postcard. If you have a list of past customers, you can ask AI to create 3-4 variations so the same people don't get identical messages every year. 5. Repeat this process once for each service type you offer. Save each template in a notes app or document so you can reuse and update them seasonally. This turns 30 minutes of writing into a 2-minute copy-paste job every time you want to reach out.
