Questions

Where does Mailchimp's export fill Last Name and Company, which Salesforce requires?

Last Name comes from Mailchimp's Last Name column; Mailchimp's export has no column for Company, so add one before you import. The checker above counts the rows with Last Name blank.

Where do NOTES, MEMBER_RATING and the other columns go?

Into Description on each lead, labeled like "- Notes: Asked about the annual plan.".

What happens to unsubscribed contacts?

Mailchimp exports include all contacts regardless of subscription status. This template maps the contact fields but doesn't set email opt-out in Salesforce. Filter out unsubscribed rows before importing, or update the Do Not Email field in Salesforce after.
