BCC an additional email on PMPro admin emails.

my_pmpro_email_headers_admin_emails.php

/*
Add bcc for PMPro admin emails
*/
function my_pmpro_email_headers_admin_emails($headers, $email)
{		
	//bcc emails already going to admin_email
        if(strpos($email->template, "_admin") !== false)
	{
		//add bcc
		$headers[] = "Bcc:" . "otheremail@domain.com";		
	}
 
	return $headers;
}
add_filter("pmpro_email_headers", "my_pmpro_email_headers_admin_emails", 10, 2);

If we need more than one bcc address, is the code:

$headers[] = "Bcc:" . "otheremail@domain.com, otheremail2@domain.com";
or
$headers[] = "Bcc:" . "otheremail@domain.com", "otheremail2@domain.com";

Hi there, the first one should work!

Is there any way to get this to work for approval emails? (from the approvals add on)

It doesn't work for those emails, I think because those email templates use a different naming convention, but I am not sure.

@837y4rt8 There's a forked version of this gist that also handles approval emails, you can find it here:
