 * Does this plugin direct all WordPress mail through AmazonSES or just Mailster
   mail?
   If the latter, why does it complain when FluentSMTP is installed?
 *     ```wp-block-code
       The wp_mail() method already exists from a different plugin! Please disable it before using Mailster for system mails!
       ```

 * Hi There!
 * Depending on the settings you can either use `wp_mail` or not. Read more about
   this [here](https://kb.mailster.co/how-can-i-use-mailster-with-the-wp_mail-function/).
 * Hope that helps!
