The right regions are those in which your e-mail recipients are located. For example, if you are a European company advertising in the U.S.A., North America is the right region for you. To select a region, click Add or remove the region you do not want. Per default, Delivery Watch monitors all major region-independent ISPs such as Hotmail and Yahoo, since these services are used worldwide. Please note that the standard edition of Delivery Watch only allows for monitoring of one additional region.
