# Changing your language

Wiz has two separate language settings, and it helps to know which one you're changing:

- **App language** - the language of the Wiz interface you work in.

- **Email language** - the language your emails to customers are written in.

They're independent, so you can run the app in one language and send emails in another.

## Change the app (interface) language

Go to **Brand & Settings** and change the **app's language**. This updates the Wiz interface only - it has no effect on the emails your customers receive.

---

## Change the email language

Your email language is part of your branding. Go to **Brand & Settings → Branding → Edit branding** and change the **language** field, then save. (This is the same look & feel form you filled in during onboarding - see [Updating your branding](#).)

|| **Email language applies going forward.** Changing it here affects emails created from that point on - your campaigns and AI-generated campaigns. It does **not** rewrite the flow emails you already have (Welcome, Abandoned Checkout, and so on), which keep their original language.

## Changing the language of existing flows

If you want your existing flow emails in the new language too, you have to rebuild them with **Regenerate flows**. This recreates all your flow emails using your current branding, including the new language.

||| **Regenerating is destructive and can't be undone.** It deletes your current flows, including any manual edits, and rebuilds them from scratch. Only use it when you're willing to lose those customizations. See [Regenerating your flows](#).

## Common questions

**Can I use one language for the app and another for my emails?**

Yes. The app language and the email language are set separately, so they can differ.

**I changed the email language but my flow emails are still in the old language. Why?**

That's expected. The language change applies to emails created going forward. To change existing flows, use [Regenerating your flows](#).

**Where do I change the language customers see in emails?**

In **Brand & Settings → Branding → Edit branding**, in the language field - not in the app language setting, which only changes the interface.
