​
Change FROM Address for Specific Emails Only

To customize the sender only for certain MainWP emails (e.g., Daily Digest), use this conditional version: 
add_filter( 'mainwp_send_mail_from_header', 'myhook_mainwp_send_mail_from_header', 10, 3 );
function myhook_mainwp_send_mail_from_header( $input, $email, $subject ) {
    // Only change FROM for specific email/subject combinations
    if ( '[email protected]' == $email && 'Daily Digest' == $subject ) {
        return array(
            'from_name'  => 'Custom Name',
            'from_email' => '[email protected]',
        );
    }
    // Return original for all other emails
    return $input;
}
Adjust the $email and $subject conditions to match the emails you want to customize.
