Greets,

I always thought when sending a mass email, in the Options on which members receive the mass email, there should be a option to send to male members only, or female members only. (according to the Gender they selected when setting up a account)

This would be nice for sending a mass email to members on a gender-specific holliday, such as Mothers Day, Fathers Day, Valentine's Day... ...

That sounds reasonable as you'd just need an additional filter for custom fields when selecting the criteria of members to mail. :)

This would be quite useful!
