Golden Key Recruitment Email

This email is designed to recruit members for an international honour society. It is part of a 5-touch email series that invites students to join. Since membership is by invite-only, the email also includes an invitation code that students must use to sign up. One of the particularly compelling reasons to join is the network of other members, who can help students advance and find their carreers. That's why that message is highlighted in a callout in the sidebar on the right. Furthermore, the callout is a shield-shape, with the arrow on the bottom pointing to the "join now" button. This helps direct readers' attention to the call to action.
