That is a pretty brave claim to say this is the best email marketing services list on the planet! If you think not, please point out another. Included here are free email marketing service options along with options for large volume companies. I threw in a few fun email tools to keep it interesting. Never again say, "What are the options to send customers email?" Or, "What email management systems are out there?" At last count, there was 138. At least 10 are free.
