In your HubSpot account, navigate to Contacts > Contacts.
Click the contact's name.
Click the Actions dropdown menu and select Opt out of email.
Confirm you want to perform this action and choose Yes, opt them out. This contact will now be opted out of all future emails from your account.
Please note: if you've purchased the Business units add-on, manually opting a contact outof all email subscriptions will only opt them out of subscriptions in the Account business unit, not any additional business units you've configured.
