For part of my birthday I am finally getting an email list service/software. I could use your help as to what services and/or software you recommend.
I send out a semi-monthly email list of Utah storytelling events open to the public beyond my own gigs. There are 600 and growing emails of storytellers (about 100) and story appreciators mainly from Utah and a few from Idaho. I need to take the next level of professionalism and have a high-quality email list service.
Besides companies to use, please share general tips on features to remember.
