短縮URLはメール開封通知がわりに使えんこともない：How to Know If Your Email Has Been Read With Short URL @labnol

If you include shortened URL in your e-mail, you can track if and what time the recipient clicked on it. It also works with bit.ly and other URL shorteners offering click tracker.

For instance, if the short URL of your link is goo.gl/abc, you can see the click stats for that short URL on goo.gl/abc+ or goo.gl/info/abc. Hover over the click points in the graph and you’ll even get to know the time when the person clicked your link in the email. - Digital Inspiration

Sort of creepy, but still worth knowing.


bit.lyやgoo.glで短縮したURLは後ろに「+」を加えたアドレスで開くとクリック統計が見れるので、メール本文に短縮URLを入れて送ると、相手がそのリンクをクリックしたかどうかも、そこで確認できる。クリックした時間・回数・国・OS・ブラウザまで見えるので、正直、「そこまで見えんでええわ」と思うけど。
