Adding custom email headers (e.g; CC, BCC, Reply-To) to notification emails

Created by Phil Kurth, Modified on Thu, 23 Jun, 2022 at 4:10 PM by Phil Kurth

You may add custom email headers using the af/form/email/headers filter

function filter_email_headers( $headers, $email, $form, $fields ) {
	// Set the reply-to address
	$headers[] = 'Reply-To:';

	// Set the CC header
	$headers[] = 'CC:,';

	// Set the BCC header
	$headers[] = 'BCC:,';

	return $headers;
add_filter( 'af/form/email/headers/key=FORM_KEY', 'filter_email_headers', 10, 4 );
