Example
add_filter( 'groundhogg/email/subject', 'my_extension_personalise_subject', 10, 3 );
/**
* Prepend the contact's company name to the subject for B2B sends.
*
* @param string $subject
* @param \Groundhogg\Email $email
* @param \Groundhogg\Contact $contact
*
* @return string
*/
function my_extension_personalise_subject( $subject, $email, $contact ) {
$company = $contact->get_company();
if ( $company ) {
return '[' . $company . '] ' . $subject;
}
return $subject;
}
