SpyPig: Free Email Tracking System
Find out when your email has been read by the recipient!
Now you can stop guessing “Has my email been opened?” Make a tiny SpyPig image, put it in an HTML email, and check its private request history.
Just Pig ’em! Start at the SpyPig Factory →How it works
- Create a unique tracking image.
- Insert it into an HTML email.
- SpyPig records image requests and can notify you.
It’s free, simple, and honest about its limits: caching, privacy protection, scanners, and proxies can generate requests.
