If there is a scam link in your email, you are displaying a different link in the URL than the page the link actually directs to.
For example, your link might say google.com as readable text, but the link actually directs to knowledge.webpower.io/en.
As a result, your email is highly likely to be marked as spam, meaning you will no longer reach the inbox of your contacts anymore. Not only is this a problem for your message’s reach, but you may end up on a spam blacklist as a result.
