Klaviyo is a powerful email platform and yes, you can build birthday flows in it. But the setup is not simple: you need to collect birthday data, store it as a profile property, build the flow from scratch, configure the timing logic, and handle edge cases yourself. The Happy Birthday app for Shopify does all of this out of the box, with no Klaviyo subscription required. This comparison helps you decide which approach actually makes sense for your store’s size and technical setup.<\/p>\n\n\n\n
TL;DR: Klaviyo can send birthday emails for your Shopify store, but you need to already have the birthday data. The Happy Birthday App collects the birthdays AND sends the emails \u2013 no extra setup needed.<\/strong><\/p>\n\n\n\n If you’re already using Klaviyo for email marketing, it’s a fair question: should you build birthday flows there, or use a dedicated birthday app<\/a>? (For a full overview of what the Happy Birthday App does, check our Happy Birthday App for Shopify<\/a>.)<\/p>\n\n\n\n Here’s what most store owners discover when they try to set up birthday emails in Klaviyo:<\/p>\n\n\n\n “Wait, how do I actually get my customers’ birthdays?”<\/em><\/p>\n\n\n\n Klaviyo is great at sending emails. It’s not designed to collect birthday data. You need:<\/p>\n\n\n\n This usually means custom forms, Zapier integrations, or developer help. It works, but it’s not simple.<\/p>\n\n\n\n The Happy Birthday App solves this with a thank you page widget<\/a> that automatically asks customers for their birthday right after they purchase. No forms to build, no integrations to maintain.<\/p>\n\n\n\nThe Collection Problem<\/h2>\n\n\n\n
