EmailWatchDog is an organization providing the internet community with data and recommendations regarding the reliability of email, and the time it takes to propogate email from one point to the other.

All email does not arrive seconds after it was transmitted, nor does 100% of the email reach its user destination. If you have service level agreements (SLA), or business issues with reliably and readily exchanging email, please review the provided delay statistics.

We are currently providing SMTP email delay statistics for the following ISPs:

Comcast
Cox
Grandecom
Mindspring
Time Warner RoadRunner
Yahoo

News: latest email graphs are from 4/30/2004.
