I can't decide whether to focus on the interesting aspects/potential of your tool, or the fact that you circumvented the concern I presented, but thanks for the answer nonetheless.

The ease of this tool is inversely related to the need for it. i.e. — the more complex/high volume your inbox, the more you suffer while trying to set it up.

Maybe it would be worth implementing some "starter rules" or a "wizard" that allows the first-timer to leverage many basic rules at once, immediately.

It's the Pinterest approach, if you will. :) "Pick 5 things you like" and then they auto-follow 50 people based on your choices. Voilá! Good first experience.

Remember that features ≠ power ≠ satisfaction.

I apologize for the unsolicited suggestions; you hit my area of interest right in the middle. ;) Good luck with everything and congrats on getting to the alpha in the first place!
