Analytics, templates, functionality.
I use MailChimp for newsletters. As a graphic designer, I usually hate working with templates. With MailChimp the templates are more editable and actually save me time instead of taking my time. I also love seeing who viewed and clicked on my mails. I also really enjoy the graphics of MailChimp and the big button to press when sending out my newsletters.
Use of Solution:
It was great, very user friendly. I didn't need any help.
Other Solutions Considered:
I have tried Yesware and Smartnote.
I only use the free version of MailChimp and I find it to be perfect for my needs. Don't tell them, but I can't believe I have all that functionality for free.
Which version of this solution are you currently using?
