Ever wonder if that job application you sent was read? Does your mother, brother, sister, lover, friend read the emails you send?

Introducing, SpyPig.

SpyPig takes all the guesswork out of emails. The newly launched site with a catchy name uses the same sort of technology spammers use to see if your email is real and actively read. How? you ask. Spammers embed images in their emails. Once you open your email, the image loads and, a unique identifier is sent back to the spammer letting them know that yours is a valid email address. With SpyPig, you enter your email address, message title and then choose from a small selection of SpyPig images to embed. They range from a cute little pig, to a little text graphic reading "I know you’ve read my email!”. Or if you want to go incognito, choose the deceptive white box. Type up the email and then send as normal. SpyPig will send you an email back letting you know the email was read. SpyPig works with Gmail, Outlook, Hotmail, AOL, Yahoo,etc. However, it’ll only work with HTML email, so people who read their emails in plain text will find the image as an attachment rather than an embed. Rich-text emails don't work either. Regardless, it’s free.
