Person Partitions & Email Campaign Activity

Hi all,

The Marketo instance I am working in has multiple workspaces for different teams within the company. Each workspace is for a specific team and has a dedicated person partition.

I have been given the name of a person partition, and asked to find out when they were last sent an email.

So my questions are:

1. How can I see who the members of a person partition are?
2. How can I see when the members of a person partition were last sent an email?
3. How can I see which teams/workspaces have not sent email campaigns in the last year?
4. Is there a global report that will show the most recent email campaigns sent by all the different teams/workspaces? I need to see which teams have not sent emails lately.

Can someone please help? Thanks in advance!
