Ideal Customer
- Mailprotector is purpose-built for MSPs managing email security across multiple small to mid-sized business clients, with Shield and CloudFilter designed for rapid deployment and multi-tenant management without heavy administrative overhead.
- The sweet spot is MSPs serving SMB and lower mid-market clients — typically organizations that need enterprise-grade email protection but lack internal IT security teams.
Key Differentiators
- Mailprotector's primary differentiator is its 100% channel-only model — the company explicitly never sells direct, ensuring MSP partners are never competed against.
- Its zero trust email security approach (Shield) builds a personalized trust network per user rather than relying on traditional reputation-based filtering, earning it the 2025 MSP Today Product of the Year award, a CRN Hot Products for MSPs 2025 recognition, a 2025 SaaS Awards finalist nod, and ten consecutive quarters of Channel Program Category Leader badges across five email security categories.
Industries Served
- Mailprotector serves a broad cross-section of industries through its MSP channel, with particular relevance to healthcare, financial services, legal, education, government, and non-profit organizations.
- The company's products address compliance requirements across PCI, SEC, GLBA, HIPAA, HITECH, and SOX, making them especially well-suited for regulated verticals.
Service Coverage
- Mailprotector is headquartered in Greenville, South Carolina and operates as a global SaaS platform sold exclusively through the IT channel.
- The company supports thousands of businesses, government entities, and non-profits around the world, with no stated limitation to specific countries or regions.
Partnerships
- Mailprotector goes to market exclusively through MSPs, VARs, ISVs, and VADs, with no direct sales to end customers.
- Key PSA and billing integrations include ConnectWise, Datto Autotask, Kaseya BMS, HaloPSA, Syncro, Pulseway, Tigerpaw, Accelo, and CloudBlue PSA — all accessible via the Gradient MSP Synthesize integration hub, of which Mailprotector was the first vendor to reach full production.
Company Size & Ownership
- Mailprotector was founded in 1999–2000 by David Setzer and employs approximately 41–50 people at its Greenville, SC headquarters.
- Estimated annual revenue is approximately $6 million, reflecting a small but steadily growing company.
Compliance & Certifications
- Mailprotector was verified as a HIPAA-compliant email service by Compliancy Group, having been determined to have exceeded regulatory standards outlined in the HIPAA Privacy Rule, Security Rule, Breach Notification Rule, Omnibus Rule, and HITECH.
- The company's infrastructure runs on Amazon AWS, meaning its servers benefit from SOC 3 and ISO/IEC 27001:2013 compliance through Amazon's infrastructure.

Offerings
10 offeringsBracket
Bracket is an email encryption service that requires no apps, plugins, or passwords — users simply wrap the email subject in square brackets to trigger encryption. Recipients access encrypted messages via a secure, one-time-use link that expires after 15 minutes and is locked to the originating device. Every Bracket license includes Bracket Share, an encrypted file transfer service supporting files up to 1GB with up to 25 files per secure message.
Bracket Share
Bracket Share is an encrypted file transfer service included at no additional cost with every Bracket license. Users receive a personalized file transfer page with a customizable share link, and anyone can send encrypted files up to 1GB with up to 25 files per secure message after being validated via inbox authentication. Files sent through Bracket Share arrive in the Bracket inbox just like encrypted messages.
CloudFilter
CloudFilter is a platform-agnostic secure email gateway that provides inbound and outbound email protection for Microsoft 365, Google Workspace, on-premises, and mixed environments where MX record control is available. It uses a multi-layered probabilistic threat scoring engine and includes SafeSend for advanced outbound content controls, DLP rule templates, and compliance tools. Administrators get deep multi-tenant management controls with full audit trails and customizable filtering policies down to the individual user level.
CloudMail
CloudMail is a hosted business email service designed for light users who do not need a full email platform seat such as Microsoft 365. Each mailbox includes 25 GB of storage, POP3/IMAP sync, a browser-based webmail console, CardDAV contact sync, and built-in CloudFilter email security. It enables MSPs to split domains so power users stay on full-featured platforms while light users are right-sized to a lower-cost option on the same domain.
Radar
Radar is a DMARC management and email health platform that maps every service sending from a client's domain, then guides MSPs through authenticating senders and advancing DMARC policy to full p=reject enforcement. It manages SPF including automatic SPF flattening, DKIM key management, DMARC policy, MTA-STS, TLS-RPT, and BIMI from a single dashboard. Radar is sold bundled with either Shield or CloudFilter and generates branded reports that MSPs can use to demonstrate email security progress to clients.
SafeSend
SafeSend is an outbound content control and compliance add-on bundled with CloudFilter that gives administrators visibility and policy control over what leaves client environments. It includes pre-built DLP rule templates for risky content types, instant sender notifications when outbound messages are blocked, and the ability to automatically trigger Bracket encryption on sensitive outbound content. Administrators can define custom rules and senders can self-release blocked messages with one click if permissions allow.
SecureStore
SecureStore is a journaling-based email archiving service that automatically captures all inbound, outbound, and internal messages once a journaling address is configured. Archived messages are immutably stored with unlimited storage, configurable retention periods, and advanced Boolean search to support audits, legal requests, and compliance requirements for PCI, SEC, GLBA, HIPAA, HITECH, and SOX. Messages can be exported in .eml, .pst, or .pdf format in batches of up to 30,000 at a time.
Shield
Shield is a zero trust email security solution built for Microsoft 365 environments that combines a secure email gateway with a patented API integration for full edge-to-inbox coverage. Instead of filtering threats, it builds a personalized trust network for each user based on their existing contacts and communication history, so only wanted mail gets through. Features include a Heads-Up Display for security insights, X-ray for email analysis, Email Traffic Control, and an optional Shield Pro add-on for productivity and privacy tools.
Shield Pro
Shield Pro is an add-on tier for the Shield zero trust email security product that adds productivity and privacy features licensed per user rather than per domain. It includes Bundler, a dedicated space for non-urgent mail with AI-generated summaries; Lockbox, a secure vault for sensitive messages that requires identity confirmation to reveal even if the account is compromised; and Burner Addresses, temporary email addresses that can be created and discarded to protect a user's primary address.
XtraMail
XtraMail is an email continuity service that runs in the background and maintains a rolling 30-day copy of inbound and outbound email so clients can continue working through server outages. When an outage occurs, users log into a secure web portal on any device to access their email without interruption. XtraMail requires CloudFilter and works exclusively within that ecosystem.
