Mailer

Mailer is a global email service: it holds your site's outgoing-email settings in one place and provides a single send() method that other extensions (notably Forms) use to deliver email. Configure the sender and delivery method once, and every extension that sends mail uses it.

Settings

Configure Mailer from Unyson+ → Extensions (its settings form). You set:

• From Name and From Email — the identity outgoing email is sent as.
• Send method:
  • WordPress (default) — uses the standard wp_mail() (PHP mail / whatever your host or an SMTP plugin provides).
  • SMTP — sends through an SMTP server you specify (host, port, encryption, and username / password), which is more reliable for deliverability than PHP mail.

Activated on demand

Mailer is a dependency extension: it's typically activated automatically when an extension that needs it (like Forms) is enabled. You can also activate it directly to set global sender details for the whole site.

For developers

Send mail through the configured method from any extension or theme code:

$mailer = fw()->extensions->get( 'mailer' );

if ( $mailer ) {
    $result = $mailer->send(
        '[email protected]',
        'Subject line',
        '<p>HTML message body</p>',
        array( 'reply_to' => '[email protected]' ) // optional: reply_to, cc, bcc
    );
    // $result = array( 'status' => 1|0, 'message' => '…' )
}

Passing your own $settings array as a fifth argument overrides the saved settings for that one send. Because Mailer centralizes delivery, switching the whole site from PHP mail to SMTP is a single settings change, no consumer code changes.
