This guide explains how to create a dynamic email template that delivers the right greeting or message depending on the customer’s language. This improves communication quality and reduces the need for separate templates.

Adding Language Conditions
Templates support conditional logic.
This allows you to show different text depending on the customer’s stored language.
Use the following structure:
{% if customer.source_original_data.language == "es_ES" %}
Hola!
{% elif customer.source_original_data.language == "fr_FR" %}
Bonjour!
{% else %}
Hello!
{% endif %}Important clarifications
• The key (language) and the value (es_ES, fr_FR, etc.) both depend entirely on your integration and internal setup.
• Your system may use different language codes or store the language field under a different key.
• Always use == to compare values.
• You can add further conditions for additional languages as needed.
Customizing the Email Subject by Language
If you want to localize the subject line for different languages, you can use the same conditional logic directly within the subject field of your template.
Example:
{% if customer.source_original_data.language == "es_ES" %}
Factura pendiente de pago
{% elif customer.source_original_data.language == "fr_FR" %}
Facture en attente de paiement
{% else %} Outstanding invoice
{% endif %}Tip: Always test your subject logic in the Preview tab using customers from each language group to ensure the correct version displays.
Reviewing Your Template in the Preview
You can check your logic at any time using the Preview panel.
This lets you select a customer and confirm the correct language displays.
If the preview shows the correct output for each test customer, your conditions are set correctly.
Final Steps
Once your template is ready, save it and assign it within your automation workflow.
This ensures future communications are automatically sent in the customer’s preferred language.
