MailChannels Inbound Filtering vs Mailprotector

MailChannels Inbound Filtering blocks spam, phishing, and malware before they reach hosted inboxes. It is designed for hosting providers that handle mail at scale, with a multi-tenant setup: one MX record can protect domains across a provider’s fleet, while controls remain available for individual domains. Multiple independent detection engines identify threats, and the product says it enforces SSL/TLS, SPF, DKIM, and DMARC inline, preventing mail that fails authentication from reaching customers. Customers can manage safelists, blocklists, and false-positive recovery. Intelligent Quarantine offers senders a self-service release link, and a daily digest lets users release legitimate held messages with one click. Log Search enables customers and support agents to find messages in mail history. The service supports downstream SMTP mail servers and has a cPanel and WHM plugin; the plugin requires cPanel and WHM version 68 or higher and PHP 5.6 or higher. Setup includes domain provisioning, mail-server preparation, and routing inbound traffic through MailChannels. Pricing is on request. The product page advertises a 30-minute human response, 24/7, from engineers.

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.
