How do I get eM to recognize my "groups" as contacts?

I go to “contacts” and can see my groups in the pop down list but when I try to send an email to them, the group doesn’t work. And the group doesn’t show up in my list of contacts. What am I doing wrong?

Hello,
the “group” should appear in eM Client as Distribution list - please send me “group” from eM Client saved as .vcf. Thank you.
