[SOLVED] Adding Fields to CB Emails Plugin

The "To" substitution is wrong. Notice there is no "=" between "field" and "cb_mymod". Please also test the output of that substitution in a delimiter field to ensure it's returning the value you expect. If you're populating that field by other means (such as another auto action) ensure the email action is ordered after it (they load in order).

Wow - that did the trick! It's the only action at the moment, but it was the syntax error you spotted!

Thanks a million! I've spent stupid amounts of time on this and - as so often - it needed a fresh eye to spot the idio'ts mistake.
Great stuff, thanks Krileon
