Mailprotector vs SpamHero Business Email Security

Mailprotector makes email security and management products exclusively for managed service providers. Shield combines a secure email gateway with an API integration for Microsoft 365 environments; the company says Google Workspace support is on the horizon. CloudFilter filters email where customers control MX records, including Microsoft 365, Google Workspace, on-premises servers, hosted environments and POP/IMAP. Bracket encrypts messages when a subject contains square brackets, without requiring apps, plugins or passwords from senders or recipients. It uses AES-256, and its one-time sign-in links expire after 15 minutes or become invalid if opened from another device. SecureStore captures messages going forward and has a seven-year default retention period, which can be adjusted. Mailprotector states that it holds the HIPAA Seal of Compliance from Compliancy Group and is SOC 2 Type 2 certified. ConnectWise, Autotask and Gradient integrations support licensing or service-count synchronization and billing workflows, and are free. Radar is a free email security check; current product pricing is available from an account manager.

SpamHero Business Email Security filters incoming email for a domain in the cloud, then forwards clean messages to the customer’s mail server. Its filters cover spam, viruses, and malware, including Microsoft Office macros. A searchable quarantine lets users inspect and recover messages, and three redundant mail servers in separate data centers can queue mail for up to five days when the customer’s mail server is unavailable. SpamHero documents routing Microsoft 365 mail through its service and connects with Microsoft Entra ID to set up valid email addresses; Google Workspace support is also listed. Mail-server communication uses opportunistic TLS, and the service describes enforcing TLS for senders that support MTA-STS. Its REST API uses HTTP Basic authentication and allows 60 requests per minute per key. Support includes 24/7 chat and first-level phone support weekdays from 6am to 6pm Mountain Time. The free trial lasts 30 days and requires no payment information; there is no free plan. Pricing is per domain, with Lite at $5 a month at the introductory annual-prepayment rate.
