conflit with others plugins !

Hello

I use several plugins which helps you in particular who use emails (buddypress 2.5, BuddyPress Group Email Subscription, Invite Anyone) but also WP Better Emails and MyMail)

I wonder if there is no incompatibility. I have no error message, but in the use of groups, I get more seems not there to receive emails by touching buddypress settings 2.5)

These plugins are they compatible?
Do BuddyPress Group Email Subscription (or WP Better Emails) is still used to some thing?
I also put the message in English (more or less translates)

Regards
