When you import contacts, Mailchimp asks you to choose an email marketing status: Subscribed, Unsubscribed, or Non-subscribed (Import Contacts to Mailchimp). If you import contacts as subscribed, Mailchimp says you need permission to send them email marketing content (source). A manual import is one of the usual ways non-subscribed contacts get into an audience (About Non-Subscribed Contacts).
Non-subscribed contacts are included in your contact total and count towards your monthly contact limit (source). If an import brings your total contact count above the limit of your plan tier, you'll be subject to additional charges (source). See non-subscribed contacts and your bill for the billing side in more detail.
Source steps: Import Contacts to Mailchimp — Import your file to Mailchimp.
Click Audience, open the Subscription status drop-down, and check Email non-subscribed and SMS non-subscribed. From there you can save or export the segment (source). If you only use Mailchimp for bulk email sending, Mailchimp notes you may find more value in archiving them (source).
Export each audience, then run AudienceTrim's free audit in your browser. It counts unsubscribed, non-subscribed and cross-audience duplicates (nothing is uploaded).
Do contacts imported as non-subscribed count toward my Mailchimp bill? Yes. Non-subscribed contacts are included in your contact total and count toward your monthly contact limit.
Can I send marketing emails to contacts imported as non-subscribed? No. Non-subscribed contacts can receive transactional emails and ads, but not marketing emails.
Can I import subscribed and non-subscribed contacts in one Mailchimp import? No. Mailchimp's import tool only lets you import 1 status at a time, so use a separate import for each status.
Will re-importing change an existing contact's status to non-subscribed? No. Mailchimp says imports won't update the marketing status of email contacts already in your account.
