I am currently migrating to ExactTarget and wondering how to best use Lists and Data extensions.
I have a large volume of Subscribers and according to the docs: http://help.exacttarget.com/en/documentation/exacttarget/solution_guides/using_a_list_versus_a_data_extension/ it seems I should be using Data Extensions to store them. This is fine, as DE's Import job runs relatively fast.
However, from what I've experimented with, it seems like I can only create an Email Send job if I link this data extension to the Subscriber list or create a Publication list to work off of and run and Import job on the List. This is extremely slow, as I end up having to import millions of rows into the list. This especially becomes a problem if I'm trying to update data on an hourly cadence.
Is there a way to directly send off of a Data Extension? If not, what is the best way to deal with Email Sends on a large volume of Subscribers? Please let me know if I'm going about this completely off the mark.
Thanks in advance!
