Use AI to draft referral request messages to past customers that sound personal and get more word-of-mouth work.

Word-of-mouth is the best marketing for plumbers, but asking past customers for referrals can feel awkward or pushy. Most plumbers either skip it entirely or send generic messages that get ignored. AI can help you write warm, personal referral requests that feel genuine and make it easy for happy customers to recommend you. Here's how to create a batch of referral messages in minutes that you can customize and send throughout the month. 1. Open ChatGPT or Claude and tell it you want to write referral request messages for past plumbing customers. Describe your tone (friendly, appreciative, not salesy) and mention the type of work you do most often. 2. Ask AI to generate 3-5 different versions of the message so they don't all sound identical. Include a clear ask (referrals, reviews, or both) and make it easy for them to respond or forward your details. 3. Review the drafts and pick your favorite, or mix elements from multiple versions. Personalize each one slightly before sending—add the customer's name, mention the specific job you did for them, or reference something unique about their property. 4. Save the templates in your phone notes or email drafts so you can quickly customize and send them after completing jobs, or batch-send them to past customers during slow weeks. 5. Ask AI to create a follow-up version for customers who don't respond the first time, keeping it light and non-pushy. This gives you a two-step system without having to write from scratch twice. 6. Track which message style gets the best response and ask AI to refine that version further. Over time, you'll have a proven referral system that brings in steady new work without spending money on ads.
