I am re-installing and testing.  If this does what it promises, I will sign up for a plan.

OK  This i s good good news.
mxHero is back, with only one glitch that I can find.

1) The tracking IS working and the draft folder time is short, as outlined above.  They are processed always in under 20 sec.  Ithink the tracking function and mxHero is back!

2) The delayed mailing is not working.  I have only started testing this today, but has not worked on several attempts.  Maybe I am doing something wrong......

Guys, I am seriously beginning to wonder whether you are committed to developing a usable product with a loyal following. 

I was an early adopter, gave it up, and recurrently return to it. 

mxHero clearly has the coolest features that I would want. Every time I reinstall it, I do it with the hopes that it is working correctly. 

despite its coolness, it has one critical shortcoming... It remains unreliable. 

unless and until this problem is solved I am forced to require everyone in my organization to use a less feature rich competitor. 

I sincerely hope that you are able to resolve this problem and respond to your user base in a more timely manner. 
Guys
Was there any resolution to this issue. I have the same problem and have been watching from the sidelines.
