Send Klaviyo emails in the customer's language

Use the language STOQ syncs to Klaviyo to branch your flow and send translated back in stock and preorder emails.

Last updated

STOQ syncs each customer’s language preference to their Klaviyo profile, so you can branch your flow by language and send back in stock and preorder emails in the language the customer was browsing in.

What STOQ syncs

Section titled “What STOQ syncs”

STOQ writes two language properties to the Klaviyo profile:

Property What it is Example
locale The two-letter language code en, fr
StoqLocaleCountry Language and country combined en-US, fr-CA

Branch the flow by language

Section titled “Branch the flow by language”

  1. Open your STOQ flow in Klaviyo

    In your Klaviyo dashboard, open the flow triggered by the STOQ metric you want to translate, for example Back in stock alert (STOQ).

  2. Add a conditional split on locale

    Add a conditional split that checks the profile property locale (or StoqLocaleCountry if you want to vary by country too), with one branch per language you support.

    The Klaviyo flow canvas for the flow named STOQ - Back in stock alert (STOQ) showing a Live badge, with the left Actions panel listing Email, Text message, WhatsApp, Form and Customer Hub block under Messages plus Property update, List update and Split, and the canvas showing a Trigger block reading When someone Back in stock alert (STOQ), feeding a conditional split labeled Locale split that branches into Path #1 with the condition StoqLocaleCountry equals en-IN containing an Email action STOQ - Back in stock alert (STOQ) whose subject reads {{ event.title_incl_variant }} is back in stock! set to Live at Day 0, and a second Everyone else branch that leads straight to End.

  3. Add a translated email to each branch

    Give each branch its own Email action with the template written in that language.

  4. Set the flow live

    Set the flow to Live. Customers now receive the branch that matches their language.

Check your setup

Section titled “Check your setup”

Use Klaviyo’s Send test event from STOQ (or a test profile with a set locale) to confirm the test follows the branch you expect before going live.

Good to know

Section titled “Good to know”

Templates and their translations live in Klaviyo, not STOQ, so you write each language’s copy in the Klaviyo editor. Product and variant titles are not translated automatically in the Klaviyo path, so translate any product wording in your template. You’ll need a branch in each flow you use, including alerts, reminders, and preorder confirmations.

FAQ

Section titled “FAQ”
Do product titles come through translated?

Not through Klaviyo. STOQ sends titles in your store’s default language, so add translations in your Klaviyo template if you need them. STOQ’s built-in email sending does translate titles, covered in Send alerts in multiple languages.

Which property should I split on?

Use locale to branch by language only, or StoqLocaleCountry to branch by language and country, for example to separate fr-FR from fr-CA.

A profile has no language and falls through

Give the conditional split a default branch with your primary language so profiles without a locale still get an email.
