Global link parameters

Overview

This feature allows users to automatically append custom parameters to all tracked links in the emails. By automatically adding these parameters, users save time and ensure that all links include the necessary data for analytics, contact identification, or other business processes.

Accessing global link parameters

To access global link parameters, go to Settings > Channels > Email > Email > Add parameters to links.

Set up global link parameters

To set up global link parameters, follow the steps below.

1. Click + Add parameter to start creating your custom parameters.

2. Fill out the fields and configure the settings as needed. See the descriptions below for guidance:

• Parameter name: The name of the custom parameter you want to add to your links. Example: user_id
• Parameter value: The value assigned to the parameter. Example: {{ people.custom.userid }}

TIP: Both the parameter name and parameter value support merge tags. This means you can, for example, set a static parameter name (e.g., user_id) and have the parameter value dynamically populate for each contact based on their user_id field in the CDP.

To add a merge tag, click the user icon:

• Campaign type: Select whether this custom parameter should apply to all campaigns, only automation campaigns, or only one-off campaigns.
• Scope: Select whether this custom parameter should apply to all links regardless of domain, or only to specific domains. You can also choose to exclude certain domains instead.

Use cases

Here are a few examples of where adding custom parameters to your links can help simplify workflows, automate processes, and ensure the right data gets passed along:

• User auto-logging with hashed IDs: Include a hashed contact ID in links so that when recipients click, they are automatically recognized in your system. Example: Adding user_id=abc123hashed to links to automatically log the recipient in.
• Dynamic personalization: Automatically include personalized parameters in links to tailor landing pages or offers for individual recipients. Example: Adding user_type=premium or region=EMEA to links so the recipient sees content relevant to their profile or location without manual edits.
• Custom business parameters: Add any custom parameters required by third-party systems, CRM workflows, or internal tracking needs. This is useful when links need to trigger specific processes or pass information without manual intervention.
