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”
$web = get-spweb -identity "http://dotnetsharepoint.com/sites/SharePoint2013/BusinessUsers"
$groupss = $web.Groups.GetByName("DotNetSharePoint")
foreach($user in $groupss.Users)
$sendemailto = $user.Email
$totalemail = $sendemailto
#You can also get this below information from Custom List also , in the article we are mainly showing how to send email to Owners Group Using PowerShell.
$smtpserver = "yourSMTP severname"
$emailfrm = "emailidfrom whom you have to send this email"
$Subject = "We are sending email to Users"
$EmailBody = "You type some information which you want to show in side the email body"
