Send text file content as the body of an email using Send-MailMessage

Question

I am taking the last 8 lines of a bunch of robocopy logs and bunching them together.  
Get-ChildItem -Filter *.log | ForEach {
$a += Get-Content $_.Name | Select -Last 8
$a += Write-output ' '`r
$a += Write-Output '------------------------------------------------------------------------------'`r
I then wanted to use this as the body of an email (send-mailmessage).  It all works but the formatting is lost in the email. I've tried using Out-String and ConvertTo-HTML with little luck.
If I look at $a in the above it looks fine in the PowerShell console it's just lost when it reaches my inbox.
I am using v2 of PowerShell and sadly can't upgrade it.

Answer 1

The issue isn't that part. It's the content of the log files that loses its formatting.
$a += Get-Content $_.Name | Select -Last 8
