I'm trying to send one email per order number to a data extension. Data extension is set up so contact id relates to subscribers on subscriber key. No primary key. The data would look something like this:
Contact ID Name Order Number Item Number Email 123 John 001 1 firstname.lastname@example.org 123 John 002 2 email@example.com 321 Jane 003 3 firstname.lastname@example.org 321 Jane 003 4 email@example.com
I'm using this data to personalize the email with an order summary with AMPscript similar to this solution. As you can see, there will be multiples of the same contact, sometimes multiple items on the same order number. What I want is to send one email per order number. Right now, when I send to this data extension, a contact will receive one email per record, so contact 321 receives two emails, even though it's just one order number. I don't want to de-duplicate either, because then contact 123 wouldn't receive two emails for his two different order numbers. Is it possible to achieve what I want here? Is there a solution in email send settings or in data extension settings?
