What you share.
WHAT IS SHARED
The server's processing, memory and connection Its address, usually Its reputation
WHAT THAT MEANS
Another account's behaviour can affect you, and yours can affect them.
WHAT LIMITS EXIST
Resource limits per account, which prevent one consuming everything.
WHAT AFFECTS YOU
Overall server load Network capacity at the server Anything affecting the shared address
THE SHARED ADDRESS POINT
Mail reputation is partly tied to the server address.
That is why abuse by one account affects others, and why we act on it promptly.
WHAT YOU CONTROL
Your own account's behaviour and efficiency.
WHAT REDUCES YOUR IMPACT
Efficient code Caching Not running heavy scheduled tasks at peak times
WHAT TO DO IF YOU SUSPECT A SERVER-LEVEL PROBLEM
Establish whether other sites on the same server are affected.
Then open a ticket with what you found.
WHAT WE CAN SEE
Server-level conditions you cannot.
