An unwelcome development: mailing list hosting services like MailChimp that edit outgoing messages. All URLs get replaced with spoofed links that point to a site you've never heard of, which does something you can't predict before sending you to the site you thought you clicked on. This behaviour is indistinguishable from what phishers do when they try to get you to click on fake banking sites; if you configure your email client to ignore warnings about it, you'll be leaving yourself open to the phishers too.

London Klezmer Quartet, that means you.
