Is it possible to update records in Marketo via their "ID" number? I can't seem to find the field when attempting a list upload.
What if I need to update a number of records that don't have an email address. How do I update those records en mass? I'd much rather do all my updating via a Marketo id number than an email address. Especially since you have have both a lead and contact records in Marketo with the same email address.
