Hi @jh999
Thanks for your question. Klaviyo is profile-centric regardless of subscription status (consented to receive email), which allows you to use Klaviyo as a CRM to understand transaction history and other data points about your customers even if they are not consented to receive email, these would be your non-subscribed contacts. However, these contacts can still receive emails, commonly triggered emails list Cart Abandon or Browse Abandon (if you have that enabled and setup), but since they have not specifically opted in, you would want to message them cautiously.
If you prefer to suppress contacts from receiving any messages in the future, then you will want to upload them directly to the suppression file.
To do that, you would navigate to the Profiles section (“Profiles” is found in the left-hand navigation), then click on Suppressed Profiles in the upper right-corner of the Profile screen.
When you’re on the suppression list you can either add an email address individually or upload a CSV file to upload a bulk list of contacts.
Checkout Klaviyo’s Guide to the Suppression List as its a really helpful resource:

I hope this helps! Please let me know if you have any other questions.
