Hi there! I understand that when you click the link from the BookFunnel email, instead of opening your book, it opens the Tap app on your Android device. Let's see if we can get this sorted out together.

Just to clarify a bit more before I guide you:
- What type of file is your book? (e.g., EPUB, MOBI, PDF)
- Are you clicking the link from an email app on your device or from a web browser?
- Do you currently have the BookFunnel app installed on your device?
- Have you tried opening the book in any other app or method?

Meanwhile, here are some initial steps that might help:

1. Install or Ensure You Have the BookFunnel App:
While not mandatory, the BookFunnel app on your Android device makes opening and managing your downloads very straightforward. If you don't have it, you can download it from the Google Play Store.

2. Open the Email Link Through the BookFunnel App (If Installed):
Sometimes tapping the download link in the email might default to opening another app like Tap if your device has it set as the default for eBook files. One way is to first open the BookFunnel app, then try to access the download link from within it or copy the link into a browser and follow through.

3. Check Default App Associations for eBook Files:
Your Android may be set to always open certain file types (like EPUB or MOBI) with the Tap app instead of the BookFunnel app or an eBook reader you want. You can check this by:
- Going to Settings
- Tap Apps & notifications
- Tap Default apps or Open by default
- Find Tap app, and clear defaults so it doesn't automatically open those files. This way, you can select a preferred app next time.

4. Download the Book File Manually and Open in Preferred Reader:
If the link continues opening Tap, try saving the file directly by holding the link (long press) and selecting "Download Link" or "Save Link." Then, open the file directly from your downloads using an ebook reader app of your choice.

Let me know what you've tried already and any other details, so I can guide you further!
