To maintain a good sender reputation, Northern Trail Outfitters should have one dedicated IP address for every
100,000 messages send per month. This will help them avoid IP throttling and blacklisting issues. A shared IP address is not recommended for their volume, and having multiple SAPs for different types of sends is not necessary. They should also send consistently and avoid large spikes or drops in their sending volume.
