In this article we can see
how to send email only from a particular group of people using power shell, it
is very easy to user to remove/add new users whenever they want. In the below
code we created a SharePoint Group with name “DotNetSharePoint”
add-pssnapin
microsoft.sharepoint.powershell
$web = get-spweb
-identity 
"http://dotnetsharepoint.com/sites/SharePoint2013/BusinessUsers"
$groupss =
$web.Groups.GetByName("DotNetSharePoint")
$emailgrouptoo =@()
foreach($user in
$groupss.Users)
{
$sendemailto  = 
$user.Email
$totalemail =  $sendemailto
  $emailgrouptoo+=$totalemail
 }
#You can also get this below

"emailidfrom whom you have to send this email"
