Do your team's emails include opt out or unsubscribe links?

yes but this feature has only been recently added to our individual emails. I personally think it is good to have and that it should be required for all emails which give the receiver the option to opt out or unsubscribe to emails they do not want to receive.

Only those coming through marketing channels (i.e. CRM) currently have unsubscribe, but watching closely to the changes in email deliverability standards to protect our client's domains. We may end up including an unsubscribe to avoid being reported as SPAM.
