Our verdict on MailMonitor
MailMonitor is a hosted email deliverability application for businesses and high-volume senders. It combines inbox placement testing across real mailboxes and ISPs with sender reputation monitoring, authentication auditing, blocklist monitoring, spam-trap neutralization strategies, analytics, scorecards, and postmaster or ISP reputation remediation. Its web and API access suit teams that need ongoing visibility as well as programmatic workflows, while managed services and enterprise engagements address organizations seeking implementation guidance and remediation support.
Pricing is structured around three annual-billing tiers. The Deliverability Foundation costs $1,000 per month and includes dashboard access, custom onboarding, a dedicated customer success manager, ticket support, monthly scorecards, and an email authentication audit. The Strategic Partnership costs $2,000 per month and adds an in-depth audit, implementation guidance, 24/7 reputation monitoring, biweekly scorecards, and B2C and B2B inbox placement testing. The $3,000-per-month Custom Enterprise Solution adds team chat, global deliverability support, custom API integrations, a dedicated account team, and a custom reporting dashboard. A 5-day free trial is available for non-Enterprise new paying accounts.
The platform’s strongest fit is for organizations that treat deliverability as an ongoing operational discipline rather than a one-time check. Its coverage spans placement, reputation, authentication, blocklists, spam traps, analytics, and remediation, with integrations for Mailchimp, SendGrid, Marketo, HubSpot, and Klaviyo, plus REST API access. That breadth and its 2010 founding year support a mature, consulting-oriented offering. Smaller senders, teams seeking a self-service tool, or buyers with limited recurring budgets may prefer an alternative with a lower entry price or a permanent free plan.
