Double Opt-In is the Add-on for Back In Stock Notifier – By default our Back In Stock Notifier core Plugin coded as Single Opt-In which means subscribers who subscribe to the product will be considered as confirmed subscription. But what if your email misused by someone in our subscribe form? Unknowingly you will receive mail regardless of person who tried your email address. To avoid this process and to support GDPR Compliance we created this add-on. Using this Add-on subscribers who enter their email will receive confirmation link in email before actually get it subscribed, if you’re not confirm through mail then your details will be automatically deleted from system(as per admin defined days – default is 7).
