Birthday Email is a free, responsive HTML template for wishing customers, members and subscribers a happy birthday, with a gift that brings them back. Birthday emails are one of the best-performing automated emails in email marketing because they're personal, expected and genuinely welcome, so they tend to see much higher opens and clicks than ordinary campaigns.

Festive without being cluttered

A confetti-and-cake hero image sets the mood, followed by an "It's your day" label, a big "Happy birthday, Jordan!" headline with a first-name merge tag and a short, warm message. The gift sits in its own bordered box: a label, the offer as a headline ("20% off anything"), the code in a dashed coupon and an expiry note. A "Claim your gift" button and a signed note finish the email.

A gift that drives action

A birthday discount or free gift gives the email a reason to act on, and a limited validity, such as 14 days or the birthday month, creates gentle urgency without feeling pushy. Switch the gift section off to send a pure greeting, or replace the code with a free item, double loyalty points or a free month.

Set it and forget it

Collect birthdays at sign-up, then set up a date-based automation in Klaviyo, Mailchimp, Shopify Email, HubSpot, Brevo or Omnisend that sends this email on the birthday or a few days before. The template is built with tables and inline styles, with an Outlook-safe button, a dark palette and a plain-text version. It's marketing email, so the footer includes an unsubscribe link and postal address. For seasonal greetings, see Holiday Greetings.
