Use AI to write a professional maintenance reminder letter that brings customers back year after year.
Most plumbers lose repeat business simply because customers forget to schedule annual maintenance. A well-written reminder letter keeps you top of mind and fills your calendar during slow periods. Instead of spending 20 minutes crafting the perfect message, let AI write a friendly, professional reminder in 30 seconds. You can customize it for different services — water heater flushes, sump pump checks, seasonal pipe inspections — and send it to past customers when the time is right. This works especially well for services people should do yearly but always forget about until something breaks.
