Once you click the Send Now button, your invite is fed into our delivery system and can't be retrieved. There is no way for us to intervene in this process. Therefore, any invites sent can not be recovered regardless of whether they are sent to a Yahoo! Mail account or any other. Once a message arrives in a mailbox, it belongs to the recipient.

If you wish to remove someone from your guest list, you may do the following:

1. Click on the Edit Guests link on the right, at the top of the Guest List section.
2. Put a checkmark by the person you wish to disinvite.
3. Hit the Delete button.

When you remove someone from your guest list, they will no longer have access to your invite.
