Cannot Get Send-MailMessage to Send Multiple Lines - powershell

Question

I apologize for this in advance because I see plenty of questions regarding it throughout the web but for some reason I'm still having issues.
I have a script that creates an array that has information dynamically added to it. When the script completes, I need it to email that information to me. The problem is that each line is combined to that I get 1 line. For example:
$Body = #()
$Body += "1"
$Body += "2"
$Body += "3"
$Body += "4"
Here's my send command:
Send-MailMessage -To $Recipients -From $Sender -Smtp $SMTP $Subject "Test" -Body ($Body | Out-String)
What I get in the email body is: 1234
I've tried this for loop to append `n to the beginning of each line (except the 1st) like so:
for ($i = 0; $i -lt Body.Count; $i++){
if($i -eq 0){
Write-Host $i
}else{
$Body[$i] = "`n" + $Body[$i]
Write-Host $Body[$i]
}
}
The results of that are better but I get an extra line:
1
2
3
4
Ultimately I just want this:
1
2
3
4
In the past, I've gotten the format I want by creating the variable like this:
$Body = #"
This is the email I want to send. It formats great if:
1) I want to make all the content static.
Is it possible to create the `$Body variable like this but add line by line dynamically and maintain a serpate line. (without extra lines)?
"#
What am I missing? It HAS to be something simple... Thanks for your help!

WOW so it's such a finicky thing... I found that using this would get everything to look right (as suggested by Ryan, above):
-Body ($Body -Join "`r`n")
But in the context of my actual script it wasn't working. Well, it appears that it all had to do with the way the date was going in there. Here's a reduction to show:
DOES NOT WORK
$Body = #()
$Body += "Beginning processing on: " + (Get-Date)
$Body += "No advertisements found, exiting"
ALSO DOES NOT WORK
$Body = #()
$DateTime = Get-Date
$Body += "Beginning processing on: $DateTime"
$Body += "No advertisements found, exiting"
When I removed anything that had to do with the Date, formatting was correct. Ultimately it just took a simple "." to make it work right.
WORKS - NOTE THE 3RD LINE
$Body = #()
$DateTime = Get-Date
$Body += "Beginning processing on: $DateTime." #Note the period at the end of the line.
$Body += "No advertisements found, exiting"
Presumably I could just concatenate and it would work but oh well, I'm keeping it as it. I didn't think that it would be that finicky about a period but now I know.
