What is a dedicated IP? A Plain-English Guide
A dedicated IP is a sending IP used only by you, so your reputation is entirely your own and not affected by other senders on a shared pool. It requires warm-up but gives you full control.
Why it matters for deliverability
Understanding a dedicated IP is part of when a dedicated IP is worth it. Get it right and more of your mail reaches the inbox; get it wrong and even legitimate mail can be filtered.
