Twilio SendGrid's Teammates feature allows multiple users, or "Teammates," to work from a single SendGrid account.
Teammates enables groups of users with different roles and responsibilities to share one account, where each of these users has access to varying SendGrid features depending on their needs. By only giving your individual team members access to the features that they need to do their jobs, you can limit access to sensitive areas of your account. Teammates makes it easy to add, remove, and manage different users. See the Teammate Permissions documentation for more information about managing user permissions.
Free and Essentials plans allow for adding one Teammate per account and do not offer Single Sign-On (SSO), while Pro and higher plans allow for up to 1,000 Teammates and include SSO and other features. Learn more about the different Email API Plans on our pricing page.
You can think of Subusers like subaccounts. Each Subuser account is its own email ecosystem with isolated contacts, templates, suppressions, and data. Subusers feed off their parent account email credits, and all billing rolls up to the parent account. Teammates may have access to a parent account, a group of Subusers, or a single Subuser account only.
