Language filtering lets you redirect visitors based on their browser's language setting. This is useful for sending visitors to localized versions of your content automatically. Available on paid plans (Growth and above).
How It Works
When a visitor clicks your deeplink, Bouncy checks the Accept-Language header from their browser. If their primary language matches one of your language rules, they're redirected to the URL you've specified for that language.

Regional campaigns — direct visitors to country-specific landing pages based on language
Localized offers — show different promotions based on the visitor's language
Tips
Language detection is based on browser settings, not location. A French-speaking visitor in the UK will match French language rules.
Combine with geo-filtering for more precise targeting (e.g., French-speaking visitors in Canada vs. France).
If a visitor's language doesn't match any rule, they're sent to the default destination URL.
