Mac OS X Hints: Sending long URLs from e-mail apps. If you send URLs to contacts using your e-mail program, you may have an issue where the receiving client breaks really long URLs.
For instance, if you were trying to send a URL for a site like this one: ref=amb_link_4263902_/002-5510588-1062447 You might find that your recipients are unable to click on the link in their e-mail program. That’s because many e-mail programs will do what I did above—break really long “words” (for that’s all a URL is to them) into multiple rows. Persistent URL Home Page.
