Hi Mike,
Thank you for the quick reply!
That sounds like it will work. It also helps me understand the use of the mailusers_update_custom_meta_filters function. I can use the native Xprofile meta query function to pull meta values that can be updated in a new meta key in the user meta.
I’d like to give it a try and post my results back here.
Thanks for your help and for your work on this plugin!
