What Maysoft does
Maysoft is a privately held, bootstrapped email security and productivity software company that has operated continuously since 2003 (with corporate roots traceable to its predecessor, MayFlower Software). The company develops native anti-spam, anti-virus, and email verification solutions for three platform bases: HCL Domino and HCL Notes, Microsoft Exchange Server, and Microsoft 365. Its core product, SpamSentinel, has filtered email natively on Domino servers since 2003 and expanded to Exchange in 2010, achieving documented block rates of 99-99.6%. The product portfolio includes SpamSentinel (on-premise for Domino and Exchange, plus a hosted cloud variant), Verisend (visual email verification for Notes and Microsoft 365, with a free side-loaded and paid Pro edition), Positive Identity (native SPF/DKIM/DMARC authentication for Domino), 2ndLookSecurity (12-factor phishing detection for Microsoft 365), MacroKiller (claimed 100% CryptoLocker macro-virus blocking), and InboxGenius (behavioral inbox management). Threat detection is enabled through a technology partnership with Cloudmark's Global Threat Network, and the hosted cloud service runs on DuoCircle infrastructure.
The business operates a per-user annual subscription model with no server-based fees, including free cross-platform license migration between on-premise and cloud deployments. Pricing is intentionally low-ARPU, with Positive Identity at $4.25 per protected user per year. Distribution combines direct inside-sales (Frank Paolino, Allison Cote), self-serve trial downloads from the company website, freemium entry for Verisend on Microsoft 365, and a regional channel partner network in Sweden, Chile, Denmark, Canada, Germany, and Czech Republic. Professional services — covering migrations, Microsoft 365 support, and Azure advisory — supplement software revenue.
Maysoft serves a niche but durable customer base that includes large nonprofits (Salvation Army, 50,000 users), manufacturers (Imerys, Munters, Rawlings Sporting Goods, Milliken), government entities (Walworth County), and utilities (Knoxville Utilities Board), with a small team of 11-50 employees operating from Massachusetts and Santa Barbara. The company is founder-owned with no external institutional investment and no disclosed revenue figures, positioning it as a long-lived, cash-generative specialist vendor focused on the HCL Domino/Notes installed base and adjacent Microsoft platforms.
