Launched recently, the new Post SMTP add-on has some really intriguing features.

This feature allows you to send emails from the backend, which speeds up front-end load times. An email is recorded in the backend and queued to be sent in accordance with the settings whenever a form is submitted or an email request is triggered.

To activate this wonderful feature, simply toggle the button.

There are four settings in this Advance Delivery Tab.

1. Batch Settings.
2. Quota Settings.
3. Auto Retry.
4. Logs.
