Email and SMS campaigns for a electrical company
Most electricians sit on a list of several hundred past customers and never contact them again. That list is the highest-margin work available to you, because acquisition is already paid for and these people have watched your tech work in their house.
The list is worth the most at two moments. The days after an outage, when surge protection at $600 to $900 and generators are suddenly on everyone's mind. And the eight weeks before your storm season, when a maintenance or inspection offer books the slow calendar before it gets slow.
The mistake is a monthly newsletter. Nobody reads a newsletter from their electrician. Trigger-based messages tied to a real reason work: the house that hit fifteen years on its panel, the customer who mentioned buying an EV, the $4,800 service upgrade quote that went quiet six weeks ago. SMS costs a cent or three a message. After two weeks, working means the quote follow-up sequence is live and old quotes are coming back.
