  4. Designing a personalized email template


  5. Setting up the automation and testing it


Let’s break it down step by step.


1. Collect Customer Birthdays or Anniversary Dates


To send Klaviyo birthday emails, you need to collect customers' birthdates or the date they first signed up. You can do this by:


  • Adding a birthday field to your signup forms


  • Collecting birthdays during checkout


  • Running an email campaign asking customers to update their profile


How to Add a Birthday Field to a Signup Form in Klaviyo:


  1. Go to Klaviyo > Navigate to Signup Forms


  2. Create a new form or edit an existing one


  3. Add a custom field > Name it "Birthday"


  4. Set the input type to "Date"


  5. Save and Publish the form


Now, every new subscriber will have their birthday stored in Klaviyo.


2. Store Birthdays Using Custom Properties


Klaviyo stores birthday and anniversary data as custom properties in user profiles.


How to Add a Custom Property Manually:


  1. Go to "Profiles" and select a customer


  2. Scroll to Custom Properties


  3. Click "Add Property"


  4. Enter "Birthday" as the property name and set a date


  5. Save Changes


To automate this, collect birthdays through forms or imports.

A flow automates birthday or anniversary emails based on customer data.


How to Set Up a Birthday Email Flow:


  1. Go to Klaviyo > Click Flows


  2. Click Create Flow


  3. Select "Create from Scratch"


  4. Choose a Trigger:

    • "Date Property" trigger for birthdays

    • Select "Birthday" as the property

    • Choose "Annually" so it repeats every year


  5. Click "Done"


Now, Klaviyo will send the email each year on their birthday.


4. Design a Personalized Birthday Email


Make your Klaviyo birthday emails engaging by including:

  • A warm greeting: "Happy Birthday, [First Name]!"

  • A special offer: E.g., 15% off or a free gift

  • A CTA (Call to Action): "Claim Your Birthday Gift"

  • A visually appealing design


How to Design the Email:

5. Automate and Test the Flow


Before activating your flow, test it:


  1. Use Klaviyo’s Preview Tool to see how it looks

  2. Send a test email to check formatting
