Consistency is my topic of the week, it seems. I did a podcast about it with Dave Misterly of AquaLife Ponds. We were talking about him having Pondtent do weekly tips for his company and how that has given him a new level of respect from his customers. He feels (and I agree) that customers want to see a company that is consistent, that is timely, that does things regularly. I notice when I get newsletters from people. Even from pond manufacturers. There are two in mind. One does their newsletter at the same time each month (Company A) , with the same number of stories. Consistency. The other one (Company B) comes out sporadically. Sometimes there's tips, sometimes not. Sometimes photos, sometimes not.
It changes your view of the company-- I think of company A above as a more together company in general. The companies might be the same size or the second one may be bigger, but it's all about perception. It's all about how it looks to others.
So what is my point? It's this-- when was the last time you reached out to your customers? And the time before that? Be consistent. It makes you look like a more professional company. In all ways. If you can commit to doing your monthly newsletters yourselves, great! If not, hire someone who will.
