Level: Beginner
Choosing between a shared and dedicated sending IP is a genuine technical tradeoff, not a simple upgrade decision, and the right choice depends on sending volume and consistency.
Shared IPs Pool Reputation Across Multiple Senders
A shared IP's reputation depends partly on the sending behavior of other senders using the same pool, which can be a benefit for low-volume senders and a risk if pool-mates behave poorly.
Dedicated IPs Put Reputation Fully in Your Control
A dedicated IP's reputation reflects only your own sending behavior, but that also means poor practices have nowhere to hide behind other senders' good behavior.
Dedicated IPs Require Sufficient, Consistent Volume
A dedicated IP sent from too infrequently or in too low a volume struggles to build meaningful reputation at all, making it a poor fit for smaller or highly irregular senders.
