Technologies are generally described for an invitation management scheme. In some examples, an application provider server may include an invitation request receiver unit configured to receive, from an account of a first user, a request to invite a second user to use an application; an interest determination unit configured to determine whether the second user is inclined to use the application based at least in part on behavior information regarding activity in an account of the second user that includes a number of invitations sent to the account of the second user that remain pending; a notification generation unit configured to generate an invitation to be sent to the account of the second user after the interest determination unit determines that the second user is inclined to use the application; and a notification transmitter unit configured to transmit the generated invitation to the account of the second user.
