If you’re sending wishlist emails (via automations or campaigns) and want to track clicks using UTM parameters or any other custom query arguments, you can easily do this using built-in filters.

Available Filters for Customizing Wishlist URLs #

You can modify the wishlist link using the following filters:

How to Add UTM Parameters to Wishlist URLs in Emails #

Example: Add UTM Parameters to the Wishlist URL #

Add the following code to your theme’s functions.php file or via a code snippet plugin:

add_filter( 'wlfmc_automation_emails_list_url', function( $wishlist_url, $wishlist, $automation ) {
return add_query_arg( array(
'utm_source' => 'newsletter',
'utm_medium' => 'email',
'utm_campaign' => 'wishlist',
), $wishlist_url );
}, 10, 3 );


If you’re sending the email via a campaign, use the campaign-specific filter:

add_filter( 'wlfmc_campaign_emails_list_url', function( $wishlist_url, $wishlist, $campaign ) {
return add_query_arg( array(
'utm_source' => 'newsletter',
'utm_medium' => 'email',
'utm_campaign' => 'wishlist',
), $wishlist_url );
}, 10, 3 );


Notes #

• These filters work right before the email is sent, so no need to manually modify the {wishlist_url} placeholder in the email content.

• You can use add_query_arg() to safely append multiple parameters.

• It also works with custom query parameters unrelated to UTM tracking.

Conclusion #

To track and customize your wishlist links in email campaigns, simply hook into the appropriate filter and append your desired parameters.
