If you’re like me, then you probably send a lot of e-mail messages. I send so many that I routinely forget who I’ve contacted throughout the course of a day, week, or month. Because of this, sometimes I get surprised when an e-mail randomly arrives in response to an e-mail that I sent earlier. With that said, there are certain messages that I send where I don’t hear back from the people for a period of time and I’m left wondering whether they read what I wrote or not. I have a hard time being patient while waiting for responses, so knowing if someone took a look at my message is a big deal to me. SpyPig offers a solution that might work if this is an issue for you.

The basic idea is that you include a custom generated tracking image in your message (one of them is white, and therefore not very obvious), and when it’s viewed by the recipient, an e-mail notification will be sent to you to let you know that your message has been seen. HTML e-mail must be used for SpyPig to work, and this is a convenient solution if you only want to do this at certain times instead of continually. Just so you know, if your family members ever find out about this service, then you better be prepared to actually respond to their messages so as to avoid the inevitable guilt trips that will be forcibly placed upon you if you don’t.
