Fintech apps send more transactional emails than almost any other category: balance alerts, transaction confirmations, statement notifications, security alerts, and promotional offers. Each email is an opportunity to bring the user back to the app. But without deep links, clicking a link in an email opens the mobile website (where the user probably is not logged in) instead of the app (where they are).<\/p>\n\n\n\n

This guide covers how to build fintech email campaigns with deep links that open the right screen in the app. For Universal Links in email, see Universal Links in email<\/a>. For e-commerce email deep links, see e-commerce email deep links<\/a>.<\/p>\n\n\n\n

The Email-to-App Problem<\/h2>\n\n\n\n

When a fintech user taps a link in an email on their phone:<\/p>\n\n\n\n

Without deep links:<\/strong><\/p>\n\n\n\n

    \n
  1. Email link opens the mobile website.<\/li>\n
  2. User is not logged in on the mobile web.<\/li>\n
  3. User must log in (enter email, password, 2FA).<\/li>\n
  4. User navigates to the relevant page.<\/li>\n
  5. Most users abandon at step 3.<\/li>\n<\/ol>\n\n\n\n

    With deep links:<\/strong><\/p>\n\n\n\n

      \n
    1. Email link opens the app directly to the relevant screen.<\/li>\n
    2. User is already authenticated in the app.<\/li>\n
    3. User sees the content immediately.<\/li>\n<\/ol>\n\n\n\n

      The difference in engagement is significant. Deep-linked emails in fintech see 2-3x higher tap-through rates because users know the link will open the app, not a mobile web login page.<\/p>\n\n\n\n

      Email Categories and Deep Link Patterns<\/h2>\n\n\n\n

      Transactional Emails<\/h3>\n\n\n\n

      These are triggered by user actions or system events:<\/p>\n\n\n\n

      Email Client Considerations<\/h2>\n\n\n\n
      Universal Link Behavior in Email Clients<\/h3>\n\n\n\n
      Not all email clients handle Universal Links the same way:<\/p>\n\n\n\n
      \n\n\n\n\n\n\n\n\n
      Email Client<\/th>\nUniversal Link Behavior<\/th>\n<\/tr>\n<\/thead>\n
      Apple Mail<\/td>\nUniversal Links work natively<\/td>\n<\/tr>\n
      Gmail (iOS)<\/td>\nOpens in Gmail's in-app browser first. User may need to tap "Open in Safari" for Universal Link to trigger.<\/td>\n<\/tr>\n
      Gmail (Android)<\/td>\nApp Links work if properly verified<\/td>\n<\/tr>\n
      Outlook (iOS)<\/td>\nOpens in Outlook's in-app browser. Limited Universal Link support.<\/td>\n<\/tr>\n
      Outlook (Android)<\/td>\nApp Links work with some limitations<\/td>\n<\/tr>\n
      Yahoo Mail<\/td>\nVariable behavior across versions<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n
      Working Around In-App Browsers<\/h3>\n\n\n\n
      Some email clients open links in an in-app browser instead of triggering the Universal Link. Workaround:<\/p>\n\n\n\n
        \n
      1. The deep link lands on a web fallback page.<\/li>\n
      2. The web fallback page detects the in-app browser.<\/li>\n
      3. It shows a prominent "Open in App" button.<\/li>\n
      4. The button uses a Universal Link that the in-app browser will handle correctly (or falls back to the app store).<\/li>\n<\/ol>\n\n\n\n
        Link Tracking and Universal Links<\/h3>\n\n\n\n
        Email marketing platforms (SendGrid, Mailchimp, etc.) often wrap links for click tracking:<\/p>\n\n\n\n
        Original: https:\/\/links.finapp.com\/accounts\/ACC-789\nTracked:  https:\/\/email.sendgrid.net\/track\/click?u=abc123&url=https:\/\/links.finapp.com\/accounts\/ACC-789\n<\/code><\/pre>\n\n\n\n
        This tracked URL breaks Universal Links because the domain (email.sendgrid.net<\/code>) is not your app's domain.<\/p>\n\n\n\n
        Solutions:<\/strong><\/p>\n\n\n\n
          \n
        1. Disable link tracking for deep links.<\/strong> Most ESPs allow excluding specific links from tracking.<\/li>\n
        2. Use your own tracking domain.<\/strong> Configure your ESP to track clicks through your domain.<\/li>\n
        3. Track in the app instead.<\/strong> When the app opens via a deep link, log the event to your analytics.<\/li>\n<\/ol>\n\n\n\n
          Security in Fintech Emails<\/h2>\n\n\n\n
          Link Verification<\/h3>\n\n\n\n
          Fintech emails are a target for phishing. Help users verify legitimate emails:<\/p>\n\n\n\n
