VSL:WEB // Make sure your e-mails are being opened

You send an e-mail. Days pass with no response. Then your intended recipient claims to have never received it. Is he lying? If you used SpyPig — a sly little tool that tells you when an e-mail’s been opened — you’d know for sure.

Here’s how it works: Your e-mail gets embedded with an image — a cartoon pig. When that image is downloaded from SpyPig’s server, the application sends you an instant notification. (One caveat: You and your target both need to be using HTML-friendly e-mail programs in order for the application to work.) Intrusive? Maybe. Creepy? Perhaps. But if curiosity’s getting the best of you, go on — be a pig about it.
