For example, we have a 4-part educational series that I'd like to space a few days apart to be delivered by Intercom email. We're introducing the option to opt-in via another series (an onboarding series) with a link in the message that says something like, "Want to learn more about [this really cool thing]?
However, I can't see how to trigger the educational series when the person clicks that link. Is there another/better way to do this?
