Email and SMS campaigns for a septic company
A septic company's customer list is the best marketing asset it owns and almost nobody uses it. Every tank pumped three to five years ago is due again. A list of 800 tanks on a 3.5-year cycle means about 20 are due every month, and the homeowner has forgotten who came last time.
The campaign is a text, not a newsletter: "It has been about three years since we pumped your tank on [Road]. We will be in [town] the week of the 10th, $350 if you book that week. Reply YES and I will confirm a day." Texts to past customers typically book 8% to 15%. That is 15 to 30 pump-outs a month from an afternoon of work and no ad cost. Seasonal versions go out before the thaw, the holidays and the freeze.
