Email security shouldn't be this hard
We built MailShield for the MSPs, hosting providers, and IT teams running email security across dozens or hundreds of domains. The kind of work that should be one dashboard, not a spreadsheet.
Our Story
Email is how every business communicates, closes deals, and builds trust. But when email security is misconfigured (and it often is), messages land in spam, get rejected, or worse: attackers send emails pretending to be you. The people who notice first are usually the ones managing these domains for somebody else.
We saw that existing tools were either DMARC-only (leaving blind spots in MTA-STS, BIMI, DNSSEC, DANE), priced as flat tiers that fall apart past 25 domains, or built for a single in-house team rather than an MSP juggling fifty clients. None of them treated managing a fleet as the primary use case.
MailShield was built to close that gap. We monitor all eight critical email security protocols from one dashboard, process your reports automatically, and give you clear, prioritized steps to improve. Per-domain pricing that scales with you, white-label deliverables for your clients, no automatic DNS changes, no silent policy upgrades. Just visibility, analysis, and recommendations you can trust.
