Customizing Emails by Language

[TheOtherBrian1]

When you register a user, you can create meta-data about them.

Creating meta-data with the JS-Client's signUp function

    const { data, error } = await supabase.auth.signUp({
      email: "email@some_[email.com](http://email.com/)",
      password: "example-password",
      options: {
        data: {
          first_name: "John",
          last_name: "Doe",
          age: 27,
        },
      },
    });

The above example creates a user entry that includes information about their name and age. The data is stored in the auth.users table in the auth.raw_user_meta_data column. You can view it in the auth schema with the SQL Editor.

It can be accessed in a project's Email Templates. Below is an example:

If you need to update a user's meta-data, you can do so with the updateUser function.

The meta-data can be used to store a users language preferences. You could then use "if statements" in the email template to set the response for a specific language:

{{if eq .Data.langauge "en" }}
     <h1>Welcome!</h1>
{{ else if eq .Data.langauge "pl" }}
     <h1>Witamy!</h1>
{{ else }}
     <h1>chuS'ugh, tera' je (Klingon)</h1>
{{end}}

Supabase uses the Go Templating Language to render emails. It has advanced features for conditions that you may want to explore. For more examples, there is a GitHub discussion that discusses advanced language templates.

Does this also work for email subject heading?
