A shared IP is an email-sending IP address used by many senders at once, who together build a common sending reputation on it. It is the default for most email platforms and works well for low-to-moderate volumes, since the shared traffic keeps the IP consistently active.
Shared vs dedicated IP
On a shared IP, a provider groups reputable senders so no single one has to maintain volume alone — but one bad sender can briefly affect the group. A dedicated IP isolates your reputation for full control, at the cost of warm-up and steady volume. Mailpro manages shared-pool quality with IP reputation management.
When a shared IP fits
A shared IP is the right choice for most senders below high, consistent volumes: you inherit an established reputation without warming up your own. See what a dedicated IP is to compare, and the email deliverability guide. Related: sender reputation and deliverability.
