No, Phil, I'm sorry to say that WikiTree does not have a feature to display any email messages. The only place for you to manage your email messages, either sent or received, is in your email program. You can either use a local program (the modern term is "app") on your computer or other device or your email service should have a webmail feature that permits you to manage your email account using a browser.
It may be that, if you are using an online email service (webmail), the browser application is only showing you a plain text version, which may not show links. If that is the case then you should be able to set a preference there to display HTML formatted messages, which would have links that you can click.
