I have an app and a mobile site. I also send emails to my users. I would like the following to happen if my users open these emails on their mobile phones and click on a link:
If a user has installed my app, then launch the app and open the relevant page inside it.
If a user has NOT installed my app, then launch the browser and take him to the relevant page on my mobile site.
I want this to happen seamlessly and automatically. I DON'T want to use the inbuilt android prompt as users end up choosing chrome (since it is the first option shown). How can I do this? Would ideally want solutions for both android & ios.
