Adds people to a team and sends them invite emails. Only a team admin or a workspace admin can call it. The response is the full list of members after the change, without names or emails.

Addresses already on the team are skipped. A Mixmax user whose email domain matches yours is added as already accepted, except for gmail.com and googlemail.com addresses. If the team belongs to a workspace, Mixmax users you add must be in that workspace.

The invite emails are sent before the response returns. You can make 20 of these calls per minute; over that you get a 429 with the plain-text body Rate limit exceeded.
