Email, Messaging, & Video Calls Email SpyPig Certified Email Service Review The pros and cons of using SpyPig for email tracking By Heinz Tschabitscher Writer A former freelance contributor who has reviewed hundreds of email programs and services since 1997. our editorial process Heinz Tschabitscher Updated February 09, 2020 Pexels / Mockup Photos Email Yahoo! Mail Gmail Tweet Share Email SpyPig is no longer available, but there are plenty of alternative email tracking services such as ReadNotify and Pointofmail. SpyPig lets you add small images to outgoing emails, which can tell you when the recipient opens the message. If the recipient doesn't download the image, then there's no way to tell if the message has been opened. Thus, SpyPig cannot certify email delivery in all cases. How Does SpyPig Work? To track emails, copy one of the image links on the SpyPigs site and paste it into your message. When the recipient follows the link and downloads the image, you'll receive a notification from SpyPig. You can choose from a number of designs including a blank image. If the recipient opts not to view the image, SpyPig tracking does not work. SpyPig Pros and Cons What We Like Lets you know when your email has been opened. Easy to set up on the fly. Tracks when you open your own email (e.g. in the Sent folder). Assign titles to images to make them easier to identify. What We Don't Like Requires some manual copying and pasting for every email you want to track. Recipients cannot choose whether they want their action to be tracked. Only works when the recipient downloads the remote image when opening the email.
