MailSlurp supports team accounts for organizations. Team accounts allow you to create multiple users and share inboxes and email addresses and other resources between them. You can also enable SAML SSO for your team and use your existing identity provider (IdP) to manage user access.
Organizations are a way to group users and resources together. Organizations can be used to share inboxes, email addresses, and other resources between users. Organizations enable SAML single-sign to MailSlurp via your own identity provider (IdP).
