This depends on your time commitment and budget. If you don’t have a lot of time on your hand to set up and manage your newsletter, and have discretionary funds for various advertising projects, perhaps hiring out some help would be in your best interest. If you don’t have funds to pay someone for help or a few hours a week to spare, getting creative in how you can manage your newsletter to stay in contact with customers may be your only option. It will be a slow growing project, but eventually you will figure out something that works for you and your company!
