I was skeptical at first, but gave rasa a try. Unlike what I expected, the setup was easy. I could use this to run efficient newsletter campaigns on autopilot. The database of content is a bonus. The integration with Sendfox is very handy (although it's a 1-way integration).

I hope for more designing features and flexibility in the future, especially the ability to embed media in the text zone. More allowance for contacts would help a lot, especially for those with a large emailing list.
