I did that a few weeks ago, but I think the "one email a day" format is really bad for such a thing, it's just too slow to find something that suites you.

It's probably a bit like dating.

I'm using dating websites since 2002 now, leaving one, joining another, using about 3-5 simultaneously.

I find like... 4 interesting women a year and only 1 in 2 years finds me interesting.

And most women I had relations with, I met outside of these portals.
