Mail Science is an email deliverability audit and inbox monitoring tool, designed primarily to help permission-based marketing emails reduce the chances of landing in spam. Its site emphasizes the ability to audit, fix, and maintain MailChimp accounts, while monitoring changes in filtering rules from Google, Microsoft, and others. It is best suited for teams that rely on email marketing for acquisition, conversion, or content distribution.
The product covers several key parts of the deliverability chain. Inbox vs. Spam testing shows where emails land across different ISPs after sending; AI Content Checker identifies words, links, and content risks that may trigger spam filters; and Predictive Engagement Score forecasts opens and clicks before a campaign is sent. It also provides dashboards for sender score, complaint rate, bounce trends, blacklist status, spam-trap hits, and more. Authentication features include automated SPF, DKIM, and DMARC fixes, SPF flattening, zero-downtime DKIM rotation, DMARC enforcement, and BIMI readiness. The site claims real-time monitoring across 25 ISPs and provides targeted recommendations for Gmail, Outlook, and Yahoo.
The Basic Plan starts at $99/month and includes an inbox audit, sender-score boost, SPF/DKIM/DMARC auto-fix, AI content checking, Gmail/Outlook placement reports, AI contact segmentation and suppression, plus email and chat support. Growth and Enterprise both require contacting sales. Growth includes a dedicated delivery engineer, 24/7 live inbox monitoring, automated email validation, and priority support. Enterprise adds unlimited volume and subdomains, an SLA, custom MTA or ESP integrations, security audits, health checks, and 24/7 Slack and phone support. The site also offers a free inbox audit/consultation and says no credit card or code is required.
The main advantage is that it covers authentication, content, reputation, ISP placement, and pre-send prediction, making it a good fit for systematic deliverability troubleshooting. Its support for Google/Microsoft Postmaster-related recovery is especially useful for teams sending to Gmail and Outlook. The drawbacks are that Growth and Enterprise pricing is not public, payment methods, regional availability, and a full list of ESP integrations are not specified, and the performance claims on the site are mostly based on customer testimonials rather than independently verifiable data.
Mail Science is suitable for newsletter startups, SaaS growth teams, CRM/lifecycle marketing teams, affiliate marketers, and businesses with higher sending volumes that are experiencing spam placement, bounces, complaints, or declining sender reputation. The site does not provide evidence regarding accessibility from mainland China, so its status is currently unknown; payment methods are also not specified. Possible alternatives include Mailchimp’s built-in analytics, Google Postmaster Tools, Microsoft Postmaster, GlockApps, Validity Everest, Mailreach, and others.
