Definition
Shared IPs are the default for most email platforms. Multiple customers send through the same IP pool, which means one sender's poor practices can affect everyone on that IP. Dedicated IPs give you exclusive control but require warmup and consistent volume to maintain reputation. Shared IPs work well for senders with lower volume (under 100,000 per month) and those who prefer not to manage IP reputation. Dedicated IPs are better for high-volume senders, transactional email, and senders with strict deliverability requirements.
Why It Matters
This matters because the choices you make here show up directly in your results. Dedicated IPs are better for high-volume senders, transactional email, and senders with strict deliverability requirements. When this is handled well it supports engagement, delivery, and the trust subscribers place in your brand; when it is neglected, the effects tend to show up in declining performance and harder-to-fix problems further down the line.
