# Adding customized data to e-mails

Sent e-mails can be fully customized using our [JavaScript API](https://help.pickzen.com/developers/customization-guide/api):

```
Extension.setGlobalValue(id, value);
```

For example, you could send the current date adding this code that will be executed just before the pickzen is completed: 

![](/files/-MJBkG5kNsUSbEXmhSYA)

In this example, the parameter **current\_date** will be available in the email template using **%current\_date%**

![](/files/-MJBkzYPPlD64GDMGVlr)

Being the received email:

![](/files/-MJBlLl5exogREc3HW7u)
