If you receive requests to join my Grammarly team from people you did not invite, it means your invite settings are configured to allow anyone with your corporate domain to discover your Grammarly team and request to join it. This option is enabled by default for Grammarly Enterprise customers who use SAML single sign-on, while in other plans, it is enabled by admins.
To review pending membership requests, go to the Members page and select the Membership requests tab at the top. From there, you can accept or decline these requests.

Note: Membership requests are automatically canceled if no action is taken within 30 days.
If you’d like to stop receiving membership requests, go to the Invite Settings page and select Only invited colleagues can join your account:
