SPEKTRA Edge E-mail Sender

Another 3rd party service we use apart from Auth0 is Sendgrid. You should see its config in iam/config/apiserver.proto. It is a second service for emails, Auth0 itself is used for emails too, like verification accounts. After all, Users are stored in the Auth0 service, IAM just gets copies.

However, invitations (ProjectInvitations and OrganizationInvitations) are sent using Sendgrid. See iam/invitationpublisher directory.
