It's even better when the email has been forwarded a few times:

>>>> http://www.example.com/blue-widgets-green-widgets-sexy-widgets-f
> ree-widg
>> ets-guide-to-widgets-/

There is one thing you can design in to the URL structure to help alleviate the problem.

Use http://www.example.com/142892-blue-widgets-green-widgets-sexy-widgets with a record number at the beginning of the path, and where the PHP script checks the slug text is correct for the given ID and then issues a redirect to the correct URL if it is not.

This allows a visitor using any truncated URL, perhaps like http://www.example.com/142892-blue-widgets-gre to still see the content, but crucially, to see it at the correct URL.
