Double opt-in
A subscription process requiring users to confirm their email address by clicking a verification link.
Definition
Double opt-in (or confirmed opt-in) is a subscription process where users must verify their email address by clicking a confirmation link after initial signup. This extra step ensures the email address is valid, owned by the subscriber, and intentionally submitted. Double opt-in results in higher-quality lists with better engagement and is required by law in some countries (e.g., Germany).
Examples
- Step 1: User enters email on signup form
- Step 2: User receives confirmation email
- Step 3: User clicks "Confirm Subscription" link
