Question
De-duplicating leads using Phone Numbers
I have a list of leads from a tradeshow which doesnt have any email addresses, but it does have phone numbers, I want to enter these in to Marketo and make sure duplicates are not created and are existing leads are simply added to the new list.
How should I go about doing this? Is it possible to de-dupelicate using a phone number as a common denominator?
