# Send unique coupons for your subscribers birthday

### How does it work?

1. You ask your customers for their birthday (using plugins or in your subscription popup).
2. Personal Discount generates a unique coupon code one day before your users birthday and pushes it to Mailchimp.
3. Mailchimp sends the coupon code in an email, using the normal Birthday campaign.

### Configuring Personal Discount

First of all, we will configure Personal Discount to generate coupons one day before your users birthday. 

1. Visit your dashboard and click on the "**CREATE AUTOMATION"** button.
2. Select "When it's a user birthday"
3. Configure the automation for your needs.

### Configuring Mailchimp

The last step is to configure Mailchimp to send the email. Visit your Mailchimp dashboard and create an automated birthday campaign, by clicking on "**Say 'Happy Birthday'**"

To display the coupon in your email, use the merge tag configured earlier (**\*|COUPON\_01|\*** in our case).

### Conclusion

Birthday marketing campaigns are one of the most efficient campaigns you can set up. If done well it can make your customer feel special and increase sales significantly. Not using them is losing money, so better starting now!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.personaldiscount.io/woocommerce-and-magento/send-unique-coupons-for-your-subscribers-birthday.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
