How it was done
To eliminate multiple calls to web services when validating username and password, we sped up the calling process by utilising the dotmailer Application Program Interface (API) Software Development Kit (SDK). For the re-subscribe process, we used a simple HTML template generated from dotmailer, which also uses elements in Zuken’s Sitecore CMS.
The sign-up form allows users to re-subscribe once unsubscribed using the same used for new registrations. To make the registration journey seamless. The interception of unbranded HTML responses make it appear as though website visitors have not left Zuken’s website.
