Only three out of my last six published posts is in my mail queue! Not what per post subscribers are looking for.
50% success rate is not good enough. Those that were mailed took up to THREE HOURS and I have wp-cron set to 0 as suggested.
I'm a little ticked off because I spent the whole of yesterday setting up and tweaking MailPress, even testing. Now it doesn't work like it's supposed to :(
