Building relationships is the #1 way to gain and retain customers. There is no better way to promote your business then to send fun, "non-salesy" newsletters.
It's more important to send "authentic" priented newsletters consistently then any other form of marketing!
Your goal should be to connect with your clients at least once a month. A good rule of thumb to remember is for every month you DON'T connect with your clients, you lose 10% of the value of your relationship. So if you let it go for 10 months, you've probably lost them. we spend so much time trying to GAIN new customers, but then forget about nurturing the relationship once we have them.
When newsletters are mailed to prospects, the sender becomes the first onces they call when they were ready to hire their services! Why? Because they kept hearing from them in a fun, non-salesy way. they didn't keep trying to "sell" them, they just kept sending the newsletter every month - a subtitle reminder that we're always available and ready to go work whenever they're ready.
