The year is claimed with a single database insert that succeeds for exactly one caller, so the customer gets one birthday coupon however many runs overlap. **A birthday is a day in your shop’s calendar, not an interval.** It is worked out in your store’s own timezone, so a shop in Auckland does not send its coupons on the wrong day for four months of the year. And 29 February is observed on 28 February in a common year, because somebody born on it has a birthday every year. **A date of birth is personal data, and this plugin treats it as such.** It is stored on the customer’s account and nowhere else, shown back to them in My Account so they can change or clear it, included in WordPress’ own personal-data export, removed by its erasure request, and **deleted when the plugin is uninstalled. The coupons themselves are never deleted: a code you have already emailed is a promise. #### Features * A single-use coupon emailed a week before each customer’s birthday * A percentage off, or a fixed amount off the cart * An expiry in days, counted in your store’s own timezone and written into the email * Codes with a random tail nobody can guess from their own * The date asked for in My Account, on the classic checkout, or both * Ordinary WooCommerce coupons, so they work at the classic checkout, the block checkout and the Store API with nothing to configure * **No tracking, no external requests, ever** — this plugin never phones home #### Careful about the details * Every coupon is email-restricted, limited to one use in total and one per customer, and marked individual-use. * A run that misses a day does not send a week of late birthday greetings when it comes back. Those days have passed. * Birthdays are found with a meta query, so a store with fifty thousand customers and two hundred birthdays reads two hundred rows. * A coupon that could not be minted gives its claim back, so the customer is not silently skipped for the year. * The date is only ever stored on a customer account — a guest checkout has nowhere to keep one. #### The full edition The full edition — **Gatemi Birthday Coupons for WooCommerce**, a separate plugin sold on gatemi.com — adds a coupon on the anniversary of the day each customer joined( which needs nothing from them at all), a head start of up to 60 days before the birthday, your own subject and message for each email, your own code prefix, a minimum the coupon may be spent against, a required date of birth at the checkout, and a Birthday column on the Users list. Your settings and every date carry over, and a customer who has already had this year’s coupon here is never sent a second one. ## Screenshots [⌊The settings screen: the discount, how long the coupon lasts, and where the date is asked for.⌉⌊The settings screen: the discount, how long the coupon lasts, and where the date is asked for.⌉[ The settings screen: the discount, how long the coupon lasts, and where the date is asked for.

They can send it to a friend, but the friend cannot use it. Every coupon is restricted to the email address of the customer it was minted for. ### What if the daily job runs twice? Nothing happens the second time. The year is claimed with a single database insert before the coupon is created, so only one run can win it. ### Does it work with the Checkout block? The coupons do, at any checkout. The date field appears on the classic checkout only, so on a shop using the Checkout block customers give their date in My Account. ### Do guests get one? No. A date of birth is stored on a customer account, and a guest checkout has nowhere to keep one. ### What happens to the dates if I delete the plugin? They are deleted. A birthday is a fact about a person held for exactly one purpose, and a store that has removed this plugin has no purpose left to hold it for. The coupons already sent are kept. ### Does this plugin send any data anywhere? No. It makes no external requests of any kind. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Birthday Coupons for WooCommerce – Gatemi” is open source software.
