I inherited my Marketo instance with a lot of duplicate records (over 60k). I've reduced them to a few shy of 15k. It seems to me that part of the current problem (not necessarily the source of the duplicates originally) is that SFDC and BrightTALK are creating duplicate records (same email address) as accounts already in Marketo. I've also created a trigger notification to let me know when a duplicate record is created and so far SFDC and BrightTALK seem to be to blame.
Is there a way to create a listening campaign to prevent this? !
I'd speak with brighttalk or their docs to find out why it would create a dupe. Shouldn't you send Brighttalk leads to Marketo, not SFDC?
Marketo will always let a dupe through if it is from SFDC.
Ok, I will look into the BrightTALK documentation. The leads from BrightTALK are going into Marketo and not SFDC. This issue with SFDC seems to be separate issue of duplicate records being created.
Followup question: Is there a way to automate deduplication? -- I don't want to do it manually and I don't want to pay for the marketo service.
