Dups

[Anonymous]

I know that Marketo wont send an email to a lead more than once.  When I am pulling in email addresses to market to current customers, I am finding that I often have duplicates (dups in SFDC).  I know that Marketo doesnt d-dup from SFDC but will it really send it twice?  I set up a send campaign, thinking it would eliminate those dups but my number didn't change.  I would hate to have to export, remove dups & then re-import.
Any help is appreciated.  Thank you!

When the campaign is executed, it will check for duplicate EMAILS and only send 1 to that address.
 

The big problem is when someone has 4 email addresses and all 4 are qualify for the campaign. Marketo doesn't know all 4 Leads are the same person. That's when you need to do more than email dedupe.
