Best email testing platform......go!

Hi,

I've used Litmus in the past and have previewed the new functionalities (well, new to me). I'm looking for any feedback on Litmus and other tools. Good, back and the ugly and which integrate with Eloqua (like Litmus) and what your experience has been with it.

I run a growing team of automation users in Eloqua who would be the main users for this tool, and thinking about adding a few power users in the regions they support for further testing, helping with spam filter identification (ex: improving subject lines) and previews in other clients globally.

Any and all comments and experiences are welcome. Thank you for your time.
