[Announcements] Email health feature

Dear Mailman3.com users! Starting on July 1, 2026, we are introducing the Email Health feature on all our servers. It provides email deliverability monitoring for your Mailman server. Currently, the feature uses DMARC reports, an industry standard for email deliverability monitoring. Additional data sources are under development. The system collects deliverability data and presents it together with recommended action points and an improvement strategy. For new accounts, onboarding is automatic. Existing accounts can opt in by upgrading to a subscription plan that includes the Email Health feature. Pricing information is available on the page https://mailman3.com/plans.html New IT
