There are a great number of viable alternatives to Mailchimp at various price points that may suit you. I am particularly a fan of Getresponse and Aweber, both of whom are more Affiliate Friendly and a breeze to use. In this post I have listed a number of alternatives, and whether I believe they are useful to the Email Affiliate Marketer. Other well known alternatives include MailerLite, Moosend, Omnisend, Convertkit and Constant Contact.
