Nevertheless, there is a clever workaround. With this approach, the discount code displays as a clickable image that will redirect a customer to your store with a discount applied. Start by creating new automation in Personal Discount. Click on **Add automation**. Select **Other** as your Email Service Provider and **Happy Birthday** as the campaign type.

The next step is creating a birthday campaign in Mailchimp. You can do this using **Journey** or **Classic Automations**. Navigate to the **Mailchimp dashboard** > **Automations** > **Build from scratch**. Type your Journey name and hit **Start Building**.

Set **Birthday** as the starting point of your automation. Decide how many days before the subscriber's Birthday date you want to send a message to them and indicate the name of the field where this date is stored in Mailchimp.

**Add a Journey point**. We want to **send email**. Next, design your message. You can choose from the themes or build an email from scratch.

Customize your email template. Next, drag and drop a code element into the place where you want a discount code to be displayed. Delete the placeholder div and paste the code snippet from Personal Discount. Then replace both occurrences of **{{ email }}** with **\*|EMAIL|\*** in the code snippet. **Save & close** the code element. You will see an example discount code in your email template.

When your email template is ready, hit **Save and Return to Journey**. Then click on **Continue** and **Turn On** to activate the automation. Your automation will appear on the list in **Overview** of the **Automations** section.

From now on, your subscribers will receive a message with a discount code the day before their birthday.
