MailChimp vs Twilio

MailChimp is an email marketing service provider, founded in 2001. It is a web-based application, although data can be downloaded and for some features there is an offline application. The company's logo is a chimpanzee, and the site includes numerous chimp-related graphics and humor on its website and in its communications. MailChimp began as a paid service and added a freemium option eight years later.
