Under Settings, then Members, in the Invitations section. Choose Invite member.
You give an email address, a role, and optionally an Active until date. Owner and Admin can invite; nobody else sees the section.
What the invitee gets
An email with a link. Following it and signing in adds them to this workspace directly. No new workspace is created for them, and no free trial starts.
Invitations come from [email protected]. If one has not arrived, that is the address to look for in a spam folder, or to have IT allow.
The role
Choose from Admin, Billing Manager, or User. It defaults to User, which is the right answer more often than not, and it can be changed later without re-inviting.
Owner is not an invitable role. Ownership moves by transfer, to somebody who is already a member. See Managing members.
An Admin doing the inviting can only offer Billing Manager or User.
Active until
An optional date after which their access ends automatically. See Temporary access.
Pending invitations
The section lists everything not yet accepted, and lets you resend or cancel. An invitation that has passed its window shows as Expired; send a fresh one.
Cancelling an invitation is instant and takes nothing away from anyone, since an unaccepted invitation grants nothing.
Seat limits
On Starter, a workspace has two seats. Above it, unlimited. Creating an invitation is refused if it would take you past the limit, so free a seat first, or move up a plan. Disabled members do not count. See Plans for Screenly.
