Using Mailchimp for Salesforce how do I see on a Contact record in SF that an email has been sent to them using Mailchimp?

I have synced contacts from SF to Mailchimp using Mailchimp for Salesforce and am using the free version of Mailchimp.

1. Am I correct that with the free version when sending an email campaign from Mailchimp, this cannot sync back to a Campaign in SF?

2. How do I see on the Contact record in SF that an email has been sent to that Contact via Mailchimp?

Thanks
