Reputation
What is IP reputation?
The standing of the IP address your mail is sent from.
How it works in practice
On a shared IP it is the combined behaviour of everyone using that address; on a dedicated IP it's yours alone. New IPs have no history, which receivers treat with caution, so they need a gradual warm-up.
The common mistake
Sending at full volume from a brand-new IP on day one.
