I am volunteering for a non-profit organisation registered as charity. We recently implemented Marketo thanks to an internal licence donation program.
Our database consists of internal members, local representatives and local business. We are subject to all

We send a campaign inviting new leads to opt-in. The flow sets unsubscribe to true after sending the email out.
There is a very noticeable unsubscribe link in the email body using {{lead.Unsubscribed:default=}} in addition to the default one.
