IP reputation
An IP address carries a history. Mail systems, security services and other networks judge your traffic partly on what that address did before you had it.
What shapes it
Reputation is built from behaviour: sending spam, hosting malware, appearing in attacks or on blocklists. Mail is the most visible — a poor-reputation address lands in the spam folder — but security products and other networks use reputation too, and a bad one can quietly degrade reach. It is distinct from geolocation, which is about where an address appears to be.
How we keep ranges clean
Reputation is a shared asset on a network, which is why our acceptable use policy is strict and enforced: abuse from one customer would taint addresses used by others. Acting quickly on abuse is partly how everyone's mail keeps being delivered.
When you get new space
Check fresh addresses against the common blocklists and warm them gradually if you will send mail (mail from your server). If an address arrives with baggage from a previous life, tell us — we would rather sort out a delisting than have you fighting it alone.
