The email opt-out in Sheep acts as a system wide block. Since GDPR and the requirement for contacts to opt-in we recommend only using the opt out setting for contacts that really don't want your communications. (At absence of an opt-in should be sufficient for most and is less drastic.)

On a person, click the edit button on the Contact card to bring up the edit form. Use the switch at the bottom of the form to change the value.

Note: Transactional and templated emails can still be sent when the opt-out has been set.

Switching on email opt-out will prevent contacts from being pushed to MailChimp and will unsubscribe them from any lists that they are subscribed to.

The second opt out is from Sheep automatic emails. Sheep can be setup to send emails in response to lifecycle events e.g. a new membership, a ticket purchase, an expiring membership. The automatic email opt-out stops any of these emails getting sent.
