A subscription method with a confirmation step.
Double opt-in is a process that requires users to confirm their subscription after signing up for an email list. After entering their email, users receive a confirmation message with a link they must click to activate their subscription. This ensures that only genuinely interested users join the list, reducing spam complaints and improving list quality. Double opt-in is especially valuable in regions with strict data privacy laws like GDPR. It also builds trust and engagement by ensuring recipients truly want to hear from the sender.
