## Prepare an email template

In this part of the process, you will create an email template with a Jinjava code that contains the IDs of the [aggregate](#create-an-aggreagate) and the [recommendation](#prepare-ai-recommendations) you created in the previous steps.
1. Go to 
**Experience Hub > Email > Templates**.
1. To create a new template, click **Create new**.
2. To create a template out of an existing template, click **From template**.
2. Select the template.
3. Select the wizard:

2. **Code editor** - Create email templates in CSS and HTML.
4. To add the dynamic part to the email template (last bought product and AI recommendations), you use Jinjava and add your own CSS. Below you can find an example Jijnava code.
