What is an IP address?

An IP address is a unique address that identifies your mail server on the internet. If your mail server's IP address is placed on a blacklist, it will likely prevent your email from being delivered! SimplyCast's Blocklist Monitoring service will help keep you informed of changes to the status of your IP address(es) and let you know if they have been listed or delisted from any of the Blacklists we monitor!
