ISP Monitor checks for email delays at major US and European Internet service providers, allowing you to see current mailing conditions. If there are significant delays, you may wish to postpone sending a message to particular domains or to your entire list.
The report displays the name of the ISP, the average length of time it took between the sending of a message and its receipt, and an icon indicating the status:
