This worked for me:

$SMTPServer = "smtp.gmail.com"
$SMTPPort = "587"
$Username = "[e-mail]"
$Password = ""

$to = "[e-mail]"
$cc = "[e-mail]"
$subject = "Email Subject"
$body = "Insert body text here"
$attachment = "C:\test.txt"

$message = New-Object System.Net.Mail.MailMessage
$message.subject = $subject
$message.body = $body
$message.to.add($to)
$message.cc.add($cc)
$message.from = $username
$message.attachments.add($attachment)

$smtp = New-Object System.Net.Mail.SmtpClient($SMTPServer, $SMTPPort);
$smtp.EnableSSL = $true
$smtp.Credentials = New-Object System.Net.NetworkCredential($Username, $Password);
$smtp.send($message)
write-host "Mail Sent"

However, you may get this error message:

"The SMTP server requires a secure connection or the client was not authenticated. 
The server response was: 5.5.1 Authentication Required. "

This is because the default security settings of Gmail block the connection, as suggested by the auto message from Google. So just follow the instructions in the message and enable "Access for less secure apps". At your own risk. :)

Send email with attachment using powershell -

    $EmailTo = "[e-mail]"  // [e-mail]
    $EmailFrom = "[e-mail]"  //[e-mail]
    $Subject = "zx"  //subject
    $Body = "Test Body"  //body of message
    $SMTPServer = "smtp.gmail.com" 
    $filenameAndPath = "G:\abc.jpg"  //attachment
    $SMTPMessage = New-Object System.Net.Mail.MailMessage($EmailFrom,$EmailTo,$Subject,$Body)
    $attachment = New-Object System.Net.Mail.Attachment($filenameAndPath)
    $SMTPMessage.Attachments.Add($attachment)
    $SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer, 587) 
    $SMTPClient.EnableSsl = $true 
    $SMTPClient.Credentials = New-Object System.Net.NetworkCredential("[e-mail]", "xxxxxxxx");    // xxxxxx-password
    $SMTPClient.Send($SMTPMessage)

"The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required."

I recently ran into this issue with attempting to automate messages through my Gmail account. I do not like the option of allowing "access for less secure apps". I want forward thinking security. So I continued my search.

My solution was to enable "2-Step" verification. This provides a slightly more secure solution as it provides an alternate password for your script to access your account.

Stefan's link also has this solution, but it's buried in the comments and I didn't originally find it there until after I found it on my own through searching my Gmail account. That's why I am posting it here.
