I am looking for an auto generated delivery system of new blog posts to email. I was using feed burner through Google it worked once and hasn't worked since. I've signed up for all these email marketing tools but if I understand right, it just collects the email? Then I have to use another system to create a template and generate the email separately? I don't have time for that. Is there something that does both and is free or relatively inexpensive and reliable?
Thanks in advance!

You can look at Mailchimp's RSS functionality.

Thanks! I found acymailing and installed that extension. however I'm having issues with it. Initially I installed the K2 version. Then I installed the starter and disabled the K2 version. Seemed like it was working well, but I couldn't a test message to send properly. The newsletter wasn't in the email. So I deleted the newsletter and tried to start over. But now whenever I go to create a newsletter and go to tag an article it gives me an error. Any suggestions on how to fix that?

You need to address this issue to the extension's developer.

Ok - so it was actually an issue with godaddy. They said I need to rename the file named class.phpmailer.php. Would you be able to tell me how to go about fixing that?

Hello,

This file is not a part of K2.
