The problem is it doesn&#8217;t automatically know your Shopify customers&#8217; birthdays. You need a way to collect that data first, then sync it to Mailchimp, and then trigger the automation. This step-by-step guide covers the complete setup: from birthday collection in Shopify to a live birthday email campaign in Mailchimp. The <a href=\"https:\/\/apps.shopify.com\/happy-birthday-discount\" target=\"_blank\" rel=\"noopener\">Happy Birthday app for Shopify<\/a> handles the data collection and passes birthday fields to Mailchimp so your automation runs without manual work.<\/p>\n\n\n<p><strong>TL;DR: Mailchimp can send birthday emails. But it doesn&#8217;t collect birthdays from Shopify. That&#8217;s the missing piece most merchants don&#8217;t realize until they&#8217;re already set up.<\/strong><\/p>\n<p>Mailchimp is everywhere. Probably the most well-known email platform out there. And yes, it has birthday automation. Sounds perfect for your Shopify store, right? Here&#8217;s the thing nobody tells you upfront: when you connect Mailchimp to Shopify, customer data syncs over, but birthdays? Empty field. Mailchimp doesn&#8217;t know when anyone&#8217;s birthday is. (Looking for something simpler? Check out the <a href=\"https:\/\/newcraft.dev\/apps\/happy_birthday\/\">Happy Birthday App for Shopify<\/a>.)<\/p>\n<h2>The Shopify-Mailchimp Birthday Gap<\/h2>\n<p>Here&#8217;s what happens when you set up Mailchimp with Shopify:<\/p>\n<ol>\n<li>Customer names sync \u2713<\/li>\n<li>Emails sync \u2713<\/li>\n<li>Purchase history syncs \u2713<\/li>\n<li>Birthdays? Nothing.<\/li>\n<\/ol>\n<p>Because Shopify doesn&#8217;t collect birthdays. There&#8217;s no birthday field at checkout. Customer accounts don&#8217;t ask for it. So Mailchimp has nowhere to pull that data from.<\/p>\n<p>Mailchimp&#8217;s birthday automation sits there, ready to go, with zero birthdays to trigger on.<\/p>\n<h2>How to Actually Get Birthday Data<\/h2>\n<h3>Option 1: Mailchimp Signup Forms<\/h3>\n<p>Add a birthday field to your Mailchimp popup. When people subscribe, they enter their birthday too.<\/p>\n<p>The catch: this only captures people who fill out your form. Customers who buy without subscribing? No birthday. Your existing customers? You&#8217;d have to ask them to subscribe again just to get their birthday.<\/p>\n<h3>Option 2: Import a Spreadsheet<\/h3>\n<p>If you&#8217;ve got birthday data somewhere \u2013 old CRM, customer surveys, whatever \u2013 you can import it.<\/p>\n<p>The catch: one-time fix. Doesn&#8217;t help with new customers. And if your dates aren&#8217;t formatted consistently (spoiler: they probably aren&#8217;t), you&#8217;ll spend hours cleaning the data.<\/p>\n<h3>Option 3: Use an App That Does Collection<\/h3>\n<p>This is what most merchants end up doing. Apps like the <a href=\"https:\/\/apps.shopify.com\/happy-birthday-app-new-craft\" target=\"_blank\" rel=\"noopener\">Happy Birthday App<\/a> collect birthdays on the <a href=\"https:\/\/newcraft.dev\/posts\/why-the-thank-you-page-is-the-best-place-to-collect-birthdays\/\">thank you page<\/a> after checkout, then sync to Mailchimp.<\/p>\n<p>Customer buys \u2192 enters birthday \u2192 data flows to Mailchimp \u2192 automation triggers. No manual work.<\/p>\n<h2>Building the Mailchimp Automation<\/h2>\n<p>Once you have birthday data, setup is straightforward:<\/p>\n<ol>\n<li>Go to Automations, click Create, choose &#8220;Build from scratch&#8221;<\/li>\n<li>Name it something like &#8220;Birthday Email&#8221;<\/li>\n<li>Select Birthday as your trigger<\/li>\n<li>Choose timing \u2013 on their birthday or a few days before<\/li>\n<li>Design your email with your birthday message and discount<\/li>\n<li>Turn it on<\/li>\n<\/ol>\n<p>The hard part isn&#8217;t here. The hard part is getting birthdays into the system in the first place.<\/p>\n<h2>Watch Out: Date Formats<\/h2>\n<p>Mailchimp needs dates in a specific format. European customers write 05\/03 meaning March 5th. American systems read it as May 3rd. Import mixed formats and your emails go out on the wrong days.<\/p>\n<p>The Happy Birthday App handles this \u2013 you pick DD\/MM or MM\/DD based on your customer base, and everything syncs to Mailchimp correctly formatted.<\/p>\n<h2>Discount Codes<\/h2>\n<p>Two choices:<\/p>\n<p><strong>Single code for everyone<\/strong> \u2013 Create &#8220;BIRTHDAY20&#8221; in Shopify, paste it in your email. Simple. But people share codes on coupon sites.<\/p>\n<p><strong><a href=\"https:\/\/newcraft.dev\/posts\/unique-vs-fixed-birthday-discount-codes-which-strategy-works-better\/\">Unique codes per customer<\/a><\/strong> \u2013 More secure, better tracking. But Mailchimp doesn&#8217;t generate these. You need an integration that creates unique Shopify discounts and passes them to Mailchimp for each recipient.<\/p>\n<p>Dedicated birthday apps handle unique codes automatically. It&#8217;s built in.<\/p>\n<h2>Pricing Note<\/h2>\n<p>Birthday automation needs a paid Mailchimp plan \u2013 Essentials or higher. Free plan doesn&#8217;t include automation journeys.<\/p>\n<p>If you&#8217;re already paying for Mailchimp for newsletters and other flows, adding birthday automation makes sense. If you&#8217;d only use Mailchimp for birthdays? A <a href=\"https:\/\/newcraft.dev\/posts\/build-birthday-club-shopify\/\">Birthday Club<\/a> via a dedicated app is way more cost-effective.<\/p>\n<h2>The Simpler Path<\/h2>\n<p>If setting up Mailchimp for birthdays sounds like a lot \u2013 collecting data, formatting dates, syncing systems, building automations \u2013 there&#8217;s an easier way.<\/p>\n<p>The Happy Birthday App does everything:<\/p>\n<ul>\n<li>Collects birthdays at checkout (highest-trust moment)<\/li>\n<li>Formats and stores data correctly<\/li>\n<li>Sends birthday emails automatically<\/li>\n<li>Generates unique discount codes<\/li>\n<li>Supports <a href=\"https:\/\/newcraft.dev\/posts\/multi-language-birthday-emails\/\">12 languages<\/a> for international stores<\/li>\n<\/ul>\n<p>Or if you love Mailchimp&#8217;s email editor, use the app for collection and sync to Mailchimp for sending. Get the easy data collection with the builder you prefer.<\/p>\n<h2>Bottom Line<\/h2>\n<p>Mailchimp can send birthday emails. But &#8220;can&#8221; isn&#8217;t the same as &#8220;easy.&#8221; The real work is collecting birthday data from your Shopify customers \u2013 and that&#8217;s the part Mailchimp doesn&#8217;t do.

When you connect Shopify to Mailchimp, contacts sync across, but birthday data doesn&#8217;t come with them because it doesn&#8217;t exist in Shopify&#8217;s standard customer fields. You need to first collect birthdays from your customers and store them as custom data, then make that data available to Mailchimp.<\/p>\n\n\n\n<p>Most merchants don&#8217;t realise this until they&#8217;re already building the Mailchimp automation. The flow is: collect birthdays in Shopify, sync to Mailchimp as a contact field, build the birthday automation in Mailchimp. Let&#8217;s go through each step.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1: Collect Birthday Dates in Your Shopify Store<\/h2>\n\n\n\n<p>Add a birthday collection form to your thank you page or account page using the Happy Birthday app. The app adds a simple date of birth field to the customer journey and stores the birthday as a custom customer metafield in Shopify. This is the data Mailchimp needs.<\/p>\n\n\n\n<p>You can also collect birthdays via a pop-up at checkout or through a dedicated birthday landing page. The important thing is that the birthday gets stored against the customer record in Shopify.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2: Sync Birthday Data from Shopify to Mailchimp<\/h2>\n\n\n\n<p>Once birthdays are stored in Shopify, you need to sync them to Mailchimp as a contact merge field. The Happy Birthday app integrates with Mailchimp and automatically passes the birthday date as a custom merge field (for example: BIRTHDAY or BDAY) when a customer&#8217;s birthday is collected or updated.<\/p>\n\n\n\n<p>In your Mailchimp audience, go to Audience settings and verify that the birthday merge field exists. If you&#8217;re setting it up manually, create a Date merge field with a tag like BIRTHDAY. Make sure the format matches what Mailchimp expects for date-based triggers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: Build the Birthday Automation in Mailchimp<\/h2>\n\n\n\n<p>In Mailchimp, go to Automations and create a new Customer Journey or classic Automation. Select a date-based trigger and point it at your BIRTHDAY merge field. Set the trigger to fire on the date each year, and configure it to send 0 days before (on the birthday) or 7 days before if you want an early bird offer.<\/p>\n\n\n\n<p>Design your birthday email with a personalised subject line, the discount code or gift, and a clear CTA. Mailchimp&#8217;s merge tags let you include the customer&#8217;s first name automatically: *|FNAME|*. Set up a follow-up reminder email 3 days before the offer expires to recover unconverted opens.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 4: Add a Birthday Discount Code<\/h2>\n\n\n\n<p>Mailchimp supports dynamic promo codes via a connection to Shopify. If you&#8217;re using a dedicated birthday app, unique discount codes can be generated per customer and passed directly into the Mailchimp email as a personalised code. This prevents code sharing and increases conversion rates compared to a single generic code.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions: Birthday Emails in Mailchimp for Shopify<\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Mailchimp sends birthday emails, but collecting the data is on you.
