I use Live campaign and like it for it's simplicity and ease of use. There are a few features that would be helpful and hope you would consider adding to your roadmap

1. The ability to see who read the email in addition to number of reads

2. The ability to embed rss feeds within the body of an email. 

3. The integration with blogs and other mandeeps modules is great but sending an email campaign for each new post may not be desirable.  Can there be a way to create a digest and send one campaign with multiple posts. Similar to dnn messaging where I can specify notification frequency in profile settings.

4. Show unsubscribes for the campaign as a tab in the campaign dashboard in addition to link activity, server, errors etc.

5. Save html templates

6. My request wouldn't be complete if I didn't ask if live campaigns could be integrated with groups. imagine how cool it would be if a dnn social group could send their own email campaigns :)
