A customer has several values that need to be used in the body of an email send.
* The data would be stored in a reference data extension, related on SubscriberKey
* There may be one or more records for each subscriber
* The audience is generally over 1 million subscribers
* The content is time sensitive and should be sent as quickly as possible
* The customer is not using "Catch and release" sending
* The reference data extension contains 25 columns
What method should be used

Northern Trail Outfitters' marketing team is made up of a marketing manager, a marketing specialist, and a graphic designer. The team is new to Marketing Cloud and has very little coding experience. Currently, they use Excel and VLOOKUP to segment their email audiences and import them into Marketing Cloud.
