 * Hi [@rpoulin80](https://wordpress.org/support/users/rpoulin80/),
 * Thanks for reaching out & I apologize for the confusion! It appears that you’re
   currently using the **SMTP.com** mailer option under your **WP Mail SMTP -> Settings**
   page, but you have not configured that mailer by entering the required API key.
 * Please note that SMTP.com and WP Mail SMTP are two different entities. You can
   use the free version of the WP Mail SMTP plugin with mailers such as SendLayer,
   SMTP.com, Brevo, Other SMTP, etc. The WP Mail SMTP plugin acts as a bridge to
   connect your preferred email provider or email account.
 * If you want to configure the WP Mail SMTP plugin using the SMTP.com mailer, please
   refer to [this guide](https://wpmailsmtp.com/docs/how-to-set-up-the-smtp-com-mailer-in-wp-mail-smtp/).
   Alternatively, you can configure a different mailer on your site. You can view
   all the available mailers [here](https://wpmailsmtp.com/categories/docs/mailers/).
 * I hope this helps. Thanks!
