When ESP link wrapping interferes with deep link tracking, a multifaceted approach is required. Experts and marketers recommend employing specialized deep linking platforms like Branch, AppsFlyer, Firebase Dynamic Links, Adjust, and Kochava, which offer solutions designed to withstand link wrapping. Other strategies include using custom domains, deferred deep linking, dedicated deep linking services, Android App Links, and landing page redirects. It's crucial to test links extensively across different email clients and devices, and to explore options with the ESP to disable link wrapping for specific links or domains. Employing URL shorteners for easier management and tracking is also suggested. The core issue lies in ESPs adding security headers or altering links during wrapping, which can break deep link functionality differently across browsers.
