An IP address is how the Internet Service Providers (ISPs) and other mailbox providers identify legitimate mail senders. But when you get a new IP address, it doesn’t have a reputation score since mail hasn’t been sent from it yet. It’s therefore considered a “cold” IP.
So how do you successfully get inboxed with a cold IP with zero reputation? The answer is…warm it up! Two of SendGrid’s Senior Technical Account Managers (TAMS) will explain the ins and out of IP warm up: why it’s important and who needs to do it in this free webcast.
