 * Hi,
 * I seem to have a problem with the plugin slowing down the admin area of my site.
   When using the API settings, emails are being sent without a problem but the 
   following errors are shown in query monitor:
 *     ```
       GET https://api.sendgrid.com/api/mail.send.json
       400 Bad Request
       curl
   
       GET https://api.sendgrid.com/v3/stats
       400 BAD REQUEST
       curl
       ```
   
 * Sendgrid Version 1.7.3
    PHP:5.5.24
 * Any suggestions on a fix?
 * Many thanks

 * Many thanks for the fix! It’s very much appreciated.
 * The plugin is now working without error, but is there a reason why a http request
   is made on every admin page load?
