Can you also give EmailThis a shot?

As I've written in the FAQs [1], one of the key advantages of EmailThis is that you don't rely on any external service. So if a service like Readability goes down, you don't end up losing all your saved bookmarks.

Regarding search & filtering, if you are using Gmail or Outlook, you can set filters that automatically move incoming bookmark emails (that EmailThis sends) into specific folders based on keywords/tags.

You can also leverage the fulltext search that your email client provides.
