How to send automated birthday emails and coupons in WooCommerce

Choose the offer before configuring the email. A percentage discount, fixed cart discount or free-shipping coupon can all work, but set an expiry date and decide whether it applies to all products, selected products or a minimum spend.

For birthday campaigns, a unique, single-use coupon is safer than one shared code. It limits repeated use and makes it easier to connect a redemption to the recipient.

WooCommerce does not provide a native birthday field or birthday trigger. You need an extension or custom development to collect a customer’s month and day, normally through the checkout or the My account area. AutomateWoo’s Birthdays documentation supports both locations and makes collecting the birth year optional.

Tell customers why you are asking, what they will receive and how to change or remove the date. Only collect the year if your campaign genuinely needs it.

Without a birthday automation extension, a developer must add a customer date field, save it against the user, run a daily scheduled process, find customers whose month and day match, create or select a coupon and send the email. The scheduled process also needs safeguards against duplicate sends and a way to log failures.

This route is possible, but it is not a small WooCommerce setting. You must also account for the site timezone, customers without accounts, missing birthdays, leap-day birthdays, email deliverability and changes to checkout fields. A custom build is sensible only when you need rules that existing automation tools cannot provide.

With an automation extension, enable its birthday settings and turn on the customer-facing birthday field in checkout, the account area or both. In AutomateWoo, these settings are under AutomateWoo → Settings → Birthdays; the field is shown to logged-in customers who have not already supplied a birthday.

Create a workflow using the Customer Birthday trigger, then choose whether it runs before, on or after the birthday. Add a Send Email action and use the customer email address supplied by the workflow.

Create the coupon inside the workflow or prepare an existing WooCommerce coupon. For a personalised one-time offer, add the coupon-generation variable {{ customer.generate_coupon }} to the email and set its discount, restrictions and expiry in the variable options. AutomateWoo documents this approach for generating a unique code for each recipient.

Include the discount amount, expiry date, minimum spend and any product restrictions in the message. Do not rely on a preview code as a real coupon: preview coupons are mock values, so use the email test function when you need to verify redemption.

Save the workflow as a draft and test it with an administrator account whose birthday is suitable for the test, or use the extension’s test-email feature. Check the subject, personalisation, coupon code, expiry date, mobile layout and links.

Also test the failure cases: a customer with no birthday, an account with an incorrect date, a coupon that cannot be applied to the cart and a birthday close to midnight. Scheduled tasks can be delayed if your site has poor cron activity, so check the workflow logs and your mail provider’s delivery records after activation.

For most stores, the fast way is to use AutomateWoo Birthdays Add-on with AutomateWoo. It supplies the birthday field settings, the Customer Birthday trigger, birthday rules and the birthday variable, while AutomateWoo handles the workflow and email actions.

Install and activate AutomateWoo and the Birthdays add-on, collect birthdays, create the workflow, add the personalised coupon and send a test. This avoids writing and maintaining the scheduled customer lookup, coupon generation and email logic yourself.
