I have the following use case I am trying to implement:

I would like people to sign-up by themselves or to propose their friend's email through some online or offline process.
The email address would be subscribed to a dummy/free membership and a series of times messages (via reminder scheduling) would be sent to each recipient.

The idea is to start off with a welcoming email that is sent - for example 1 day after sign-up.
And then another email that is sent 3 days, another after 7, etc.

Each email message should provide the means to allow the recipient to opt-out of the process.

It looks like reminder scheduled emails do not have the ability to provide a specific group opt-out link.

Is there some other way to automate this?
