I have a couple of custom modules that completely generate the body, to, from etc in code, and then use drupal_mail to send the email. Using the standard HTMLMail setting for site-wide configuration, the emails send fine but as soon as I change it to sendgrid integration, the emails stop sending, and sendgrid doesn't show the reporting coming through. It seems to me like SendGrid integration isn't actually intercepting the drupal_mail function.
Create a custom module, build a generic email with a body, to, from and pass it through drupal_mail() function
