Every six to eight weeks, tied to the season rather than to a promotion. Roughly six or seven emails a year keeps you in mind without annoying anyone. Four sentences, one photo of recent work, and your phone number outperforms a designed newsletter.
Past customers are the cheapest source of work a handyman has, and the one almost everyone ignores. Someone who liked your work has more jobs on their list. They have simply not thought about you since you left.
The rhythm that works is every six to eight weeks, which is roughly six or seven messages a year. More than that and people tune out. Less and they forget you again.
What matters more than frequency is the framing. The email that works is not a promotion, it is a seasonal nudge:
Each one names a real seasonal problem that happens to be a job you already do.
Keep it to four sentences, one photo of recent work, and your phone number. A plain email that looks like a person sent it consistently outperforms a designed newsletter for trades work. Send on a weekday morning.
Collect the address at invoicing rather than later. Asking for the best email for the receipt gets you the address without anyone hesitating.
