Marketo ID Field - Distinguish indiviuals

[Anonymous]

It would be great to be able to use the Marketo ID field as a unique identifier when doing list uploads to update/clean up data. While the e-mail address should be unique - we always seem to have many duplicates, so it would nice to be able to have a unique field to key off in list uploads and campaigns when doing updates.

I don't understand why that is field only available in the grid view.

We have many duplicates as well and it would be nice to be able to use the Marketo ID as a filter for smart lists.

This would be a good feature.  Please vote for the Use the Marketo ID as an identifier on Upload Idea that was submitted in 2011 so as to maximize the number of votes for this.
