SendGrid recommends creating Subusers for each of the different types of emails you sendone Subuser for transactional emails and another for marketing emails. Independent Software Vendor (ISV) customers may also create Subusers for each of their customers.You can also manage Subusers in the [Twilio SendGrid application user interface](https://app.sendgrid.com/settings/subusers).
