A high percentage of the readers of Professional Distributor magazine carry one of the major brand's logos on their trucks. All the major brands are deep into using a broad-based social media program. What I mean is that the weekly email I receive from the major brands is the same email thousands of others receive at the same time. This is good marketing, but you individually have the opportunity to take it one financial step further.
Start your own simple weekly email to your customers. Show pictures of your customers standing by their new tool storage unit or using their new grinder. Mention something about you or your family to help build your personal relationships, and adding something about a customer like a birth or wedding also adds a personal touch. End with a picture of something you are promoting or maybe even a used tool you have for sale. An hour a week invested will reap significant long-term results.
