Send partners an email invitation to join your program. They sign up through the invite and land in the partner group you choose.
Go to Partners, click New partner and choose Invite partner.
Choose how many to invite:
Single: enter one email.
Bulk: enter several emails, separated by commas or by pressing Enter after each.
Choose the Partner group they'll join.
Click Invite partner, or Invite partners for a bulk invite.
Each partner gets an email with a link to sign up. Until they do, they're listed on the Invited tab of Partners.
Good to know
To add a partner without them signing up, see Manually create a partner.
You can also share a group's sign-up link instead of sending invites. See Partner groups.
