Outsourced lists no longer exist in Oempro4.
In Oempro3, you can create outsourced subscriber lists (lists that are linked to third party MySQL tables) and send email campaigns to your subscriber data which is stored in third party MySQL tables. Even this feature sounds good, there were lots of difficulties and details which were keeping it away from stability.
In Oempro4 development process, we thought a lot about this feature and finally decided to remove it from the application. Besides outsourced list, we will be providing “synchronization” feature which will allow you to keep Oempro4 subscriber lists synchronized with your third party MySQL table(s). This new feature will still provide the opportunity of outsourced lists but also provide reliability and stability.
