What is Double Opt-In?
A subscription process requiring users to confirm their email address before being added to a list.
Double opt-in (confirmed opt-in) adds a verification step after initial signup. Users receive a confirmation email and must click to verify their subscription.
Benefits: - Ensures valid email addresses - Reduces spam complaints - Improves deliverability - Creates engaged lists - Required by GDPR in some cases
Drawbacks: - Loses 20-30% of signups who don't confirm - Adds friction to subscription process
Despite lower initial numbers, double opt-in lists typically outperform single opt-in in engagement and deliverability.
Examples
- User signs up → Receives confirmation email → Clicks link → Added to list
- Confirmation email: "Please confirm your subscription"
Tips for Double Opt-In
- ✓Make confirmation emails clear and compelling
- ✓Send confirmation immediately after signup
- ✓Remind users to check spam folder
