Mailgun Launches Redesigned Dedicated IP Management Page

Mailgun has redesigned its dedicated IP management page to provide a centralized view of IP configurations. The update allows users to monitor warmup status, linked domains, sub-accounts, and IP pool assignments from a single dashboard. New filtering capabilities enable users to quickly identify unassigned IPs and access deliverability metrics directly. Additionally, the update includes link history auditing for activity occurring on or after April 23, 2026. This release represents the first phase of a broader effort to improve IP management infrastructure.
