When looking for a suitable Email Service Provider to provide you with the online system to manage your email marketing campaigns ask yourself these two questions:

1. Do I need to handle multiple opt-in lists?
2. Do I need a sequential auto-responder?

This will narrow down your choices significantly. If you’d like to have people sign up on your website/blog/facebook to different lists and offer them different automated sequential messages (aka auto-responders) then my choice would be iContact - I use it myself and recommend it to my clients.

For the ultimate in ease of use, try MadMimi.com, I recommend them to my clients who are just starting out, with zero contacts on the list. MadMimi has the most easy-to-use interface of all the ESPs I’ve tried over the years. Their customer service is the best I’ve had the pleasure of dealing with, plus they keep adding features on a regular basis. MadMimi’s free account is a fully-featured one, but is limited to 100 contacts, and you can send as many messages as you want. Read my blog post MadMimi Brings the Fun Back to Sending Email “Blasts”
