How do you add code with quotes to a file using batch? - powershell

Question

I am trying to create a batch file that will create a file that will send an email through powershell. It does many things, but email is just a snippet of it. Here is what I have so far:
REM Creates batch file with contents of the powershell script
echo "I need to add the below powershell script" > email.bat
echo "into email.bat with all the quotes included">> email.bat
echo "like what I'm doing now with appending text">> email.bat
REM powershell script to send email.
$smtp = new-object Net.Mail.SmtpClient("smtp.gmail.com")
if( $Env:SmtpUseCredentials -eq "true" ) {
$credentials = new-object Net.NetworkCredential("username","password")
$smtp.Credentials = $credentials
}
$objMailMessage = New-Object System.Net.Mail.MailMessage
$objMailMessage.From = "myemail#gmail.com"
$objMailMessage.To.Add("whereImsendingto#gmail.com")
$objMailMessage.Subject = "Logs for today"
$objMailMessage.Body = "(the logs)"
$smtp.send($objMailMessage)
In batch, I have the way to append text to another file down if what I'm adding does not have quotes, but I need to add text that includes quotes to the file.

Why don't you simply echo whithout quotes and escape possible chars <>|& with a caret ^ and double percent signs?
In a (code block) you've to also escape closing parentheses ^)
#Echo off
( Echo:$smtp = new-object Net.Mail.SmtpClient("smtp.gmail.com"^)
Echo:
Echo:if( $Env:SmtpUseCredentials -eq "true" ^) {
Echo: $credentials = new-object Net.NetworkCredential("username","password"^)
Echo: $smtp.Credentials = $credentials
Echo:}
Echo:$objMailMessage = New-Object System.Net.Mail.MailMessage
Echo:$objMailMessage.From = "myemail#gmail.com"
Echo:$objMailMessage.To.Add("whereImsendingto#gmail.com"^)
Echo:$objMailMessage.Subject = "Logs for today"
Echo:$objMailMessage.Body = "(the logs^)"
Echo:
Echo:$smtp.send($objMailMessage^)
) > "SomeFile.ps1"
