Review on Guerrilla Mail by Joey Gilbert

I love that it is free, easy to use and they offer great customer service! It's also really cheap for how many emails you get through each month - so if you're looking for something simple but still effective this could be perfect for your needs.

The only downside would be some of their templates are not very aesthetically pleasing (especially when compared with other providers). Have used them as an additional way of communicating with clients who do not want to pay for personalised mailings from my agency.
