Email sequence plan for a field services company turning one-time job customers into maintenance plan members. The deliverable is a 5-email sequence over 22 days, built around one rule: every email has one job, one audience, and one action. It includes subject lines, the purpose and call to action for each send, scheduling and segmentation notes (including buyers exiting the sequence the moment they book), A/B testing guidance, and a measurement framework focused on bookings and conversations started, not clicks alone. The appendix includes the first email in full, plus a plain-language rewrite that puts the ask in the first line.
