Email deep links work on Android but do not open the app directly on iOS.
Branch deep links in emails do not work for iOS, since Branch uses Universal Links property to launch the app. As the Universal Links work on link domains, the mailer links wrap the Branch link into a click tracking domain, and hence the final URL changes. When you click the mailer link, it redirects to Branch link on the web as the Universal Links will not work with the new domain.
For such use cases, we have Universal Email where we have partnered with different Email Service Providers (ESPs) to support direct app open, deep linking and attribution.
