Auditing active directory group and send email report

Hi All,

I want to setup a script that will automatically audit some active directory group and send a email report. 

Actually, the script is working fine but I would like to add the following below:

1- put a separation between name because the output gave just the name and sometime it's hard to distinguish..so I need to put a separation between name. 

2-I want to put the output into a table with header as below before sending it by email:

username    first name   last name 

below is the script

# Import Modules
Get-Module -ListAvailable | Import-Module
 
 
# Get domain name
$ADDomainName = $((Get-AdDomain).NetBIOSName)
 
# Get Membership in Domain Administrative Groups
set-variable domainAdmins -value (Get-ADGroupMember "Domain Admins" -recursive | foreach {$_.samaccountname}{$_.Name})
set-variable enterpriseAdmins -value (Get-ADGroupMember "Enterprise Admins" -recursive | foreach {$_.samaccountname}{$_.Name})
set-variable schemaAdmins -value (Get-ADGroupMember "Schema Admins" -recursive | foreach {$_.samaccountname}{$_.Name})

 
# Consolidated List of Accounts with Administrative Access
#$allAdmins = $($domainAdmins + $enterpriseAdmins + $schemaAdmins | sort -unique)

 
# Send Email
Write-Host 'Sending email'
# smtp server
 $smtpServer = 'smtp server here'
 # creating a mail object
  $msg = new-object Net.Mail.MailMessage
# creating smtp server object
 $smtp = new-object Net.Mail.SmtpClient($smtpServer)
# email structure
 $msg.From = 'test@test.com'
  $msg.ReplyTo = 'doNotReply@test.com'
 $msg.To.Add('destination add')
  $msg.subject = 'Audit Active Directory Domain '
 $msg.body = $('Domain Admin Users:' + '' + $domainAdmins  | sort -unique )  + '' + 'Enterprise Admin Users:' + ''+ $($enterpriseAdmins  | sort -unique) + '' + 'Shema Admin User:' + '' + ($schemaAdmins | sort -unique)

  # sending email
 $smtp.Send($msg)
