Hi there,

I also struggeled with a similar problem.

I also needed to send a mail to a group of people.  So what I did were the following.

I created a role with a group of users. I created a separate activity with a mail event.

so I set the destination users to the role.  now there are a hidden trick with this.  First trick is that you need to create a slot for each destination.

Now the only way to do this is to go to the Activity destination wizzard and click on back.

choose advance mode and then you would se that the wizzard are completely different.

choose option at first screen

second screen choose slot per destination

and choose convert role to user name.

complete the wizzard and choose a role.

go to the mail event and at the to box select destination.

I hope this post helps

regards
