When it fails, are you getting any error messages on the screen or in the MODx log?
It could be a timeout error or possibly your host limits the number of emails send in a given time period.
Here’s a snippet I wrote called QuickEmail that’s designed to diagnose email problems. It might help.
I tried to make a package out of it, but PackMan doesn’t like it for some reason. It will look a little funky without its parameters set, but just putting:
[[!QuickEmail? &debug=`1`]]
on a page and previewing the page might give you some clues.
Here’s the snippet:
