What is Double Opt-In?
ELI5 — The Simple Version
Think of opening a brand-new club. You want only the truly interested people to join, so you create a two-step entry. First, they sign up at the door and get a ticket. But to enter, they must show a wristband from a second booth. This ensures they're genuinely excited to be there! Double opt-in for emails works the same way. Someone enters their email to get a ticket. But before receiving newsletters or offers, they must click a link sent to their inbox, like showing the wristband. This way, your email list is full of people who really want to hear from you, reducing unwanted emails and keeping your list active and engaged.
