# Add URL Parameters to All Links in an Email

## Goal

Automatically add URL parameters to all links in an email for tracking and attribution.

## Background Information

You can define parameters in the group settings that are automatically appended to all links in an email. These parameters are name-value pairs and can include:

- Static values
- Personalization placeholders
- Mapp Engage variables

When personalized, placeholders are replaced with the corresponding values stored in the system during sendout.

## Procedure

1. Go to *Audience >**Group Management**> Groups*.
2. Locate the group used for sending the message and click the **Change Settings** icon next to it.
3. Open the **Tracking & Links** tab.
4. Expand the **Link Parameters** section.
5. Click the plus icon next to **Add Link Parameter**.

  - In the first input field, enter the parameter name. The name must not contain special characters or spaces.
  - In the second input field, enter the parameter value. You can:
    - Enter a static value
    - Insert a personalization placeholder
    - Use a Mapp Engage variable
  - To insert personalization or Engage variables, click the **Personalization**button.
  - To use standard parameters for web analytics, click the **Web Analytics** button.
6. Click **Save**.

The parameter will now be inserted into every link in emails sent to this group.

## Example

You want to track each newsletter using an external message ID. To do this:

- Parameter name: `exmid`
- Parameter value: `<%Message.ExternalID%>`

If you enter `november25_womenswear` in the **External Message-ID**field during newsletter setup, the resulting links will look like this:

```ruby
www.sportswear.com/?exmid=november25_womenswear
```

A tag used to insert personalized content, such as names or order details, into messages in Mapp Engage.
