Known Mailtool Issues:
1- When combining Role and Group, emails are sent to role participants only
Issue: When sending a message, if both a role and a group/section are selected for recipients, the message is only sent to participants selected by role, and not to participants selected by group/section.
Workaround: When sending a combined message to both individuals and groups, send these messages separately.
