De-Duplicate Lead Database with custom Fields

Hi Team,

I'm new in Marketo and worked before with Silverpop / IBM Marketing Cloud.

We was able to maintained our database manually by using a de-duplication filter.

This is something I'm missing in your tool.

Challenge: I would like to find contacts in database which have the same "CRM UID" but different email address.

In this Example a contact married and has now a new last name:

CRM UID          email address

500015              molly.mustermann@company.de

500015              molly.schmidt@company.de

This means I have to merge these both contacts.

I was used to click any field in my database to de-duplicate and keep behavior data alive.

Please see my attachements.

Best Johanna
