How to make use of the tempDB database in EngageOne Digital Delivery

Product Feature: EngageOne Digital Delivery

EngageOne Digital Delivery (formerly e-Messaging) does not make use of tempDB database, as it is a system database.
TempDB database is the temporary location which SQL Server uses for its own operation.
Every time SQL SERVER restarts it creates a fresh copy of tempDB.  
No object should be created in the tempDB as the TempDB objects are managed by SQL Server itself.
