How does group invitations work?

When you create the group you go through a short setup: name the group, add your branding, then invite people by email. You can also invite more later from the group dashboard.

Because branding is set before invites go out, the invitation email carries your logo. If the person does not have a Greetopia account yet, they get an email prompting them to sign up.

They get an email inviting them to join. When they sign up, they land straight in your group with credits ready to use. Until they sign up, they still count toward the group 100-member cap.

When you create the group you set a domain, for example yourcompany.com. Anyone who signs up to Greetopia with an email at that domain joins automatically, and existing users with matching emails join too. There is no member cap on domain groups.

No. Free-mail domains such as Gmail, Yahoo, Hotmail, Outlook, iCloud, and the like are blocked, because they would let anyone join and defeat the point. You can only use a domain that matches your own verified email.

No. To protect people privacy, a domain group only lists the owner and members who have actually spent a credit. Someone who has not used the group does not show up in the member list, so the group cannot be used to see who is registered at your company.

Yes, if it is a specific-people group, and they are asked to confirm first. Domain groups cannot have individual members removed, because anyone at the domain always has access. To restrict a domain group, the owner would archive it and start a new one.

Not directly. Ask the owner to remove you from a specific-people group. This keeps the owner in control of who can spend their credits, which matters because they are the one paying for the pack.
