When sending a proof email in Salesforce Marketing Cloud with "Track Clicks" unchecked, the URLs in the email appear as they are, rather than being modified by tracking parameters. This allows the marketing team to visually inspect the URLs directly within the email without needing to click through them. Disabling click tracking simplifies the review process by displaying the exact URLs as they would appear in the final email.
* Purpose of Unchecking "Track Clicks": This is commonly done to avoid generating tracking parameters in URLs, which could clutter the validation process and create confusion when reviewing or testing the email.
* Salesforce Documentation Reference: For more information on sending proofs and tracking options, refer to Salesforce Marketing Cloud Documentation on Email Studio Testing.
