Send Birthday Emails in 12 Languages: Boost Customer Loyalty Worldwide

Increase customer loyalty by 23% with multilingual birthday emails. Send personalized birthday messages in your customers’ native language across 12 supported languages.

TL;DR: The Happy Birthday App for Shopify sends birthday emails in 12 languages automatically. German customers get German emails, French customers get French – no extra work from you.

Your German customers shouldn’t receive birthday emails in English. When someone gets a birthday message in their own language, it feels personal. In English, it feels like mass marketing. (New to birthday emails? Our Happy Birthday App for Shopify explains how it all works.)

The 12 Supported Languages

The Happy Birthday App sends emails in:

  • English – UK, US, Australia, and more
  • German – Germany, Austria, Switzerland
  • French – France, Belgium, Canada
  • Spanish – Spain, Latin America
  • Italian – Italy
  • Dutch – Netherlands, Belgium
  • Portuguese – Portugal, Brazil
  • Swedish – Sweden
  • Danish – Denmark
  • Finnish – Finland
  • Norwegian – Norway
  • Russian – Russia and Eastern Europe

That covers most of Europe and significant markets worldwide.

How It Works

You don’t need to manually tag customers by language or create separate email lists. Here’s what happens:

  1. Customer signs up – Through your checkout (the thank you page widget is the easiest way), landing page, or any other method
  2. App detects their language – Based on your Shopify store’s locale settings
  3. Birthday comes around – The app sends the email in that customer’s language

A customer who browsed your store in German gets a German birthday email. Someone who shopped in French gets a French email. No extra work from you.

Setting Up Your Translations

The app comes with default birthday messages in all 12 languages. But you can (and should) customize them to match your brand voice.

For each language, you can edit:

  • The email subject line
  • The headline and greeting
  • The body text
  • The call-to-action button

You don’t need to speak all these languages yourself. The defaults are ready to use – just review them or have a native speaker polish them if you want.

The Checkout Widget Too

It’s not just the emails. The birthday signup form on your thank you page also appears in the customer’s language.

So a Spanish customer sees “Únete a nuestro club de cumpleaños” instead of “Join our birthday club.” Small detail, big difference in conversion.

Which Plan Includes This?

Multi-language support is available on the Professional plan ($40/month). The Free, Starter, and Growth plans send emails in English only.

If you’re selling primarily in one country, English-only might be fine. But if you have customers across Europe or in multiple language regions, the Professional plan pays for itself through better engagement.

Why Language Matters for Birthday Emails

Birthday emails are personal by nature. You’re celebrating someone’s special day. Sending that message in a language they don’t prefer undercuts the whole point.

Think about it: would you feel more special receiving “Joyeux anniversaire! Voici votre cadeau…” or “Happy Birthday! Here’s your gift…”? The first one connects. The second one is just another marketing email.

Compared to Klaviyo

In Klaviyo, you’d need to create separate birthday flows for each language. That’s 12 different flows to build and maintain. The Happy Birthday App does this automatically – you create one template with translations, and the right version goes to the right customer.

What About Languages You Don’t Support?

If a customer’s language isn’t in the 12 supported options, they’ll receive the English version. English is the fallback for any language the app doesn’t recognize.

Getting Started

Multi-language works best when combined with unique discount codes – that way you can track which language versions perform best.
