I would like to know how is anyone solving this issue :- 1 customer with unique email address being the identifier in Marketo is used across in marketing activities across multiple business units or divisions.
How can we create a 1 to 1 relationship on the campaign interaction with them as Marketo takes the latest activity of the customer and updates in Marketo.
Love to hear how to problem solve this situation.
Thanks
Search the Nation for "compound dedupe" to see the pros, cons, and gaps of having Marketo enable a compound dedupe key (consisting of Email Address and one other field) for your instance.
