Reactivating customers you haven't heard from in a year
Your past customer list is the warmest lead source you have. Most shops ignore it.

Send a short, personal-feeling message
'Hey, it's been a while since we did [job]. Wanted to check if you're due for [next service].' No mass-mail energy. Texts and personal emails outperform glossy campaigns.
