All site users, after registration and in accordance with the site terms of use, will receive e-mail notifications, but only when their profile is viewed by other users or when they receive a new message from site users.
If several messages are sent by the same conversation partner within a short period of time, the recipient will receive only one notification from that conversation partner.
Also, if the same user views your profile several times within a short period of time, only one profile-view notification will be sent to your e-mail address.
