According to CASL rules, if you are a club, association or voluntary organization and the recipient is one of your members, you have implied consent. For non-members who register for an event, donates or subscribes to receive emails then there is implied consent which is valid for 24 months - after which you will need to obtain express consent.

There needs to be a way to create a saved search that includes contacts that have interacted with the site in the last 24 months. Currently there is no way to select contacts that registered for an event, donated, became lapsed, or subscribed to a newsletter within the last x months (perhaps just a simple"has complied consent" search criteria - there is already one for the express consent).

Ideally, there should also be a way to automate sending out the opt-in email after the 24 month period has passed for each contact.
