What’s the difference between shared and dedicated IPs?

Shared IPs group multiple senders on common addresses. Benefits: established reputation from day one, no warmup required, cost included in standard pricing. Drawbacks: reputation depends on pool neighbors, limited control, problems from other senders affect you.

Dedicated IPs provide exclusive addresses for your sending alone. Benefits: reputation reflects only your behavior, full control over warmup and volume, isolation from other senders' problems. Drawbacks: require warmup period, need sufficient volume to maintain reputation, additional cost.

Choose dedicated when: sending over 100,000 monthly emails, reputation control matters significantly, you can commit to consistent sending, and you can manage warmup. Shared works for: lower volumes, getting started quickly, cost sensitivity, and when ESP pool quality is high.
