Question

I have no issues sending an HTML email using Send-MailMessage, but is there any way that I can insert the value of a variable?

CSV:

email,samaccountname,newSAM,
jdoe@amce.com,john.doe,jdoe,

Command:

$html = (Get-Content .\email.html)
Import-Csv .\my-file.csv |
ForEach-Object {
Send-MailMessage -SmtpServer 10.0.0.1 -Subject "Subject Here" -From admin@acme.com -To $_.email -Priority: High -BodyAsHtml "$html"
}

HTML Body: 

<html>
<head>
    <title>HTML Generator Sample Page</title>
</head>
<body>
    <p>
        <span style="font-family:times new roman,times,serif;"><span style="font-size: 12px;"><strong>Old username: $_.samaccountname </strong></span></span></p>
    <p>
        <span style="font-family:times new roman,times,serif;"><span style="font-size: 12px;"><strong>New username: $_.newSAM </strong></span></span></p>
</body>
</html>

The email body shows $_.newSAM instead of the value imported from the .CSV file. Thanks in advance for any assistance!

Solution

You have to substitute the placeholders yourself.

Change your HTML body to this (note the .NET string formatting placeholders):

<html>
<head>
    <title>HTML Generator Sample Page</title>
</head>
<body>
    <p>
        <span style="font-family:times new roman,times,serif;"><span style="font-size: 12px;"><strong>Old username: {0} </strong></span></span></p>
    <p>
        <span style="font-family:times new roman,times,serif;"><span style="font-size: 12px;"><strong>New username: {1} </strong></span></span></p>
</body>
</html>

Then, change your code to this:

$html = Get-Content -Path $PSScriptRoot\email.html -Raw; # Get HTML text as one line
Import-Csv -Path $PSScriptRoot\my-file.csv |
ForEach-Object {
    Send-MailMessage -SmtpServer 10.0.0.1 -Subject "Subject Here" -From admin@acme.com -To $_.email -Priority: High -BodyAsHtml ($html -f $_.samaccountname, $_.newSAM);
}

NOTE: In PowerShell v3.0 and later, $_ and $PSItem can be used interchangeably.
