Hi, new user here.
I've created a custom field in my Marketo database called "Vendor Codes". Each vendor code can have multiple emails attached to it. Is it possible to create a smart list based on an uploaded list of vendor codes?
For example, I have a list of 100 vendor codes. Let's say on average, there are 3 emails associated with each vendor code. So I'd like to send 300 emails to all 300 people. What is the best way to do this within Marketo? Or do I have to create a fancy INDEXED vlookup table to look up multiple values referenced per vendor code, then create a separate list to upload?
