How to Build a Birthday Club on Shopify (Step-by-Step)

A Birthday Club sounds fancy but it’s simple: collect birthdays, send discounts. Here’s how to set one up on Shopify in 30 minutes.

A birthday club on Shopify is one of the smartest retention tools you can build. Customers who share their birthday with you are signaling trust. In return, you get a recurring reason to reach their inbox every year with a personalized, relevant offer. Here’s how to set one up properly.

TL;DR: A “Birthday Club” is just a fancy name for collecting customer birthdays and sending them discounts. On Shopify, you can set one up in about 30 minutes – no developer needed.

You’ve probably seen stores promote their “Birthday Club” or “Birthday Rewards.” It sounds like a big program, but it’s simpler than you think: collect birthdays, send discounts, make customers happy. Here’s how to build one for your Shopify store. (Want the quick version? See our Happy Birthday App for Shopify.)

What a Birthday Club Actually Is

Let’s demystify this. A Birthday Club is:

  1. A way to collect customer birthdays
  2. Automated emails that send on those birthdays
  3. A discount or gift as the reward

That’s it. No membership cards, no points systems, no complicated tiers. Just “give us your birthday, get a treat when it comes around.”

The “club” framing is just marketing. It makes customers feel like they’re joining something special. But behind the scenes, it’s straightforward email automation.

Step 1: Decide How You’ll Collect Birthdays

You can’t send birthday emails without birthday data. Here are your options on Shopify:

Thank You Page Widget (Recommended)

The thank you page is the best place to ask. Customers just bought something, they’re happy, and they trust you. A small form asking “Want a birthday surprise? Enter your birthday” converts well.

The Happy Birthday App includes a checkout widget that does exactly this – no coding required.

Dedicated Landing Page

Create a “Join Our Birthday Club” page and link to it from your navigation, emails, or social media. This works well for promoting to existing customers who’ve already purchased.

You can embed the signup form on any page of your Shopify store, or even on external sites.

Import Existing Data

Already have birthdays from another source? Import them via CSV. Moving from another platform, or collected birthdays through surveys or loyalty programs? Upload the spreadsheet and you’re set.

Sync from Shopify Metafields

If you’re already collecting birthdays through Shopify customer accounts or another app, you can sync that data automatically. No need to ask customers twice.

Step 2: Set Up Your Birthday Email

The email itself should be simple:

  • Subject line: Make it obvious it’s a birthday email – see our birthday subject line guide for ideas
  • Message: Keep it short – they just want the discount code
  • Discount: Clear instructions on how to use it
  • Expiry: Give them a reasonable window (7-14 days is common)

Don’t overthink the design. A clean email with a clear call-to-action beats a fancy design that buries the discount code.

Step 3: Choose Your Discount Strategy

Two main options:

Percentage Off

Something like 15-20% off works for most stores. It’s generous enough to feel special, but not so high that it kills your margins.

Fixed Amount

A flat discount like “$10 off” works better if your products are all similarly priced. It’s also easier for customers to understand.

Should you use a single code for everyone, or unique codes per customer? Unique codes prevent sharing and let you track results better. Fixed codes are simpler to set up.

Step 4: Promote Your Birthday Club

Customers won’t join what they don’t know about. Promote it:

  • Post-purchase emails: Mention the Birthday Club in your order confirmation or follow-up emails
  • Navigation: Add a “Birthday Club” link to your footer menu
  • Social media: Occasional reminders that you offer birthday rewards
  • Product pages: A small banner mentioning birthday perks

The checkout widget handles new customers automatically. These promotions help capture existing customers who bought before you had a Birthday Club.

Step 5: Let It Run

Once set up, your Birthday Club runs on autopilot:

  • New customers share birthdays at checkout
  • The app tracks when birthdays come up
  • Emails send automatically on the right day
  • You see revenue come in

Check your dashboard occasionally to see how it’s performing. With unique codes, you can track exactly how much revenue your Birthday Club generates.

Bonus: Multi-Language Support

If you sell internationally, your Birthday Club should speak your customers’ languages. German customers should get German emails, French customers should get French.

The Happy Birthday App supports 12 languages and automatically sends the right version based on each customer’s locale.

What About Klaviyo?

If you’re already using an email platform, you might wonder if you should build birthday flows there instead. We’ve got setup guides for Klaviyo, Omnisend, and Mailchimp. Short answer: they can send the emails, but collecting the birthdays is the hard part. A dedicated app handles both collection and sending.
