The Mark doesn't give teleportation by itself, but demons can teleport. And Knights of Hell are among the most powerful demons in existence. It also gives its bearer regenerative abilities. Cutting a demon's vessel to pieces won't work if it bears the mark, and the only reason it worked with Abaddon is because she had a devil's trap bullet in her head (which, again, failed to keep her fully bound, and isn't a permanent solution when it's used on a demon bearing the Mark, like Cain).
