With Pushpage, you can create HTML newsletters that contain self-managed content, such as news and photos. You can then send these issues to any or all users in your database.
Pushpages can only be sent to users that exist in the database. Blackbaud does not recommend adding users to the database just for the purpose of sending Pushpages to them. Blackbaud recommends using a third-party email service such as Constant Contact or MailChimp to send bulk communications to users that do not exist in the On Products.
