Direct Mail and Catalog
By passing this identifier within the C3 Metrics conversion tag (as the 'account_id' parameter), C3 Metrics is able to match this unique identifier (CRM ID) to our own C3 Metrics Universal ID (C3UID)
The 'account_id' parameter represents something unique to the user, such as: account id, encrypted email address, encrypted phone number. If the same user were to return for multiple conversions, the 'account_id' would be the same.
CRM ID/Account_Id, Date of Mail Drop, Creative Name
The 'CRM ID/Account ID' is the Account ID of the consumer who has been mailed which covers instances when you mail to a current customer.
What about Prospect Direct Mail?
11/1 Display ----> 11/2 Non-Brand Search -----> 11/5 Retargeting ----> 11/7 Brand Search ----->
11/1 Display ----> 11/2 Non-Brand Search -----> 11/5 Retargeting ----> 11/7 Brand Search -----> 12/15 $399 Purchase (account id=12345)
But wait ....
It turns out that Bill was sent the 12/1 Winter Catalog and that is not part of the path ... at least not yet.
On 2/1, the Direct Mail/Catalog 'matchback' for the 12/1 Catalog drop is completed where New Customers are compared to the mailing list to determine which new customers received the mailing. Once those new customers are identified, they are added to the feed sent to C3 and here's what Bill's entry looks like in the feed sent to C3 Metrics:
12/1,winter catalog, 12345
This data is imported into C3 and the platform adds in the Winter Catalog to Bill's purchase:
11/1 Display ----> 11/2 Non-Brand Search -----> 11/5 Retargeting ----> 11/7 Brand Search ----->
12/1 Winter Catalog</b> ----> 12/15 $399 Purchase (account id=12345)
That particular conversion is then recalculated and the model is now able to properly attribute value to the 12/1 Winter Catalog.
