Send email from WordPress

The Vaartix plugin sends all WordPress email through Vaartix: password resets, contact forms, WooCommerce orders and anything else that uses wp_mail(), whatever the theme or plugin. It requires WordPress 5.9+ and PHP 7.4+. The source and full setup guide are on GitHub at vaartix-mail/vaartix-wordpress.

  1. Download the plugin

    Download vaartix.zip, the latest release. Don’t unzip it.

  2. Upload and activate it

    In WordPress, go to Plugins → Add New → Upload Plugin, choose vaartix.zip, click Install Now, then Activate.

  3. Open the settings

    Go to Settings → Vaartix.

  4. Paste an API key

    In the Vaartix dashboard, open API keys and create a key with Sending only access. It starts with vx_live_. Paste it into the plugin’s API key field.

  5. Set the From email

    Use an address on a domain you’ve verified in Vaartix, for example [email protected].

  6. Send a test email

    Save the settings, then click Send test email. The test shows up under Emails in the dashboard, with its delivery status.

Instead of pasting the key into the settings, you can define it in wp-config.php, above the /* That's all, stop editing! */ line. The constant takes precedence over the settings field:

wp-config.php
define( 'VAARTIX_API_KEY', 'vx_live_...' );
