Custom Newsletter link not redirecting

Hello,

I created a custom newsletter in sitefinity. This newsletter shows some links to pages I have also created. The problem is when I try to click those links, sitefiity does not redirect them to anywhere and the browser just does nothing.

An example link is this one:

localhost:60464/.../aa88ee3c-d13d-4751-ba3f-7538ecc6b2ca

Do you have any idea why this is happening? Please help me.

Thank you very much.
