I am really impressed with it as it’s easy to setup and has lots of videos to show you how to do things. It is also free for the first 3000 emails so it makes it low risk to try out. The analytics seems pretty good as well. Awebber is another highly rated service I did not try this though as it is not free. I have heard good things about it though.
Below are a few comparison blogs Awebber vs Mailchimp
If anyone has any feedback about my choice of mailchimp then I would love to hear your opinion in the comments
