Do shared IPs always perform worse?

Myth: False. Shared IPs do not always perform worse. Well managed shared pools from quality ESPs can provide stable, strong reputation that individual senders could not build alone.

Shared IP performance depends on pool quality and ESP enforcement. Good ESPs remove bad actors and maintain pool health. Bad ESPs allow poor senders to damage shared reputation.

Evaluate your ESP's pool management rather than assuming shared is bad. For moderate volume senders, quality shared pools often outperform poorly managed dedicated IPs.
