Leap year birthdays, privacy mode, timezone handling, embeddable forms – the details that make birthday marketing actually work.
TL;DR: The Happy Birthday App for Shopify handles the details other apps overlook – leap year birthdays, privacy options, global timezones, and embeddable forms you can place anywhere.
Birthday email apps all do the same thing, right? Collect birthdays, send emails. But the details matter – and those details can be the difference between birthday emails that outperform your other campaigns or ones that fall flat. Here’s what makes the Happy Birthday App stand out. (Full overview: Happy Birthday App for Shopify.)
Not everyone wants to share their age. Some customers will skip your birthday signup entirely if they have to enter a birth year.
Our solution: the “Hide year field” option. Turn it on, and customers only enter their birth day and month. They still get birthday emails – you just don’t know how old they’re turning.
Why it matters: Fewer form fields = higher conversion. And privacy-conscious customers actually sign up instead of bouncing.
What happens when a customer is born on February 29? Most apps either ignore them or break.
We handle it properly: leap year babies get their birthday email on February 28 in non-leap years. They’re not forgotten, and they’re not getting emails on the wrong day.
Why it matters: About 1 in 1,500 people are born on Feb 29. If you have 15,000 subscribers, that’s 10 customers who’d be left out. Small detail, but it shows you care.
Is 03/04 the third of April or March 4th? Depends where you live.
Our checkout widget lets you choose: DD/MM/YYYY for European stores, MM/DD/YYYY for US stores. Customers enter their birthday in the format they’re used to, no confusion.
Why it matters: A UK customer entering “05/06” means June 5th to them, but an American system reads it as May 6th. Wrong birthday = wrong email timing = wasted discount.
Most apps lock you into their checkout widget. Ours gives you an embed code you can place anywhere:
Just copy the code snippet and paste it wherever you want. The form inherits your styling settings.
Why it matters: The checkout thank you page is great, but it only reaches people who buy. Embedding forms elsewhere captures birthdays from browsers who haven’t purchased yet.
When you set “send at 9 AM,” we mean 9 AM in your store’s timezone – not 9 AM UTC.
The app automatically syncs your Shopify store’s timezone settings. A store in Berlin sends at 9 AM Berlin time. A store in Tokyo sends at 9 AM Tokyo time. No manual configuration needed.
Why it matters: Nobody wants a birthday email at 3 AM. Getting the timing right means higher open rates and happier customers.
When customers click the button in their birthday email, the discount code is automatically applied to their cart. No copying, no pasting, no “enter code at checkout” friction.
The email links directly to your store with the discount pre-loaded. Customers land on your homepage (or any page you choose) with their birthday discount already active.
Why it matters: Every extra step loses customers. “Copy this code and paste it at checkout” is a barrier. One click to shop with discount applied = higher conversion rates.
We support 12 languages: English, Dutch, German, French, Spanish, Italian, Portuguese, Swedish, Danish, Finnish, Norwegian, and Russian.
But here’s the smart part: if a customer’s language doesn’t have a template, we fall back to English automatically. You don’t need to create templates for every language – just the ones that matter for your store.
Why it matters: Global stores can serve customers in their native language without maintaining 12 separate email flows.
Beyond basic percentage discounts, our unique code system supports:
Why it matters: Prevent discount abuse while still making customers feel special. A 7-day expiry creates urgency without pressure.
These features aren’t afterthoughts – they’re built in from the start. Compare that to setting up birthday emails in Klaviyo, Omnisend, or Shopify Flow – where you’re piecing together solutions for each of these problems yourself.
Birthday marketing should just work, whether your customer was born on February 29, lives in Tokyo, or prefers not to share their age. That’s what this app is built for.
