SpamBrella review
Cloud filtering pairs threat defense with continuity, replay and archiving.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SpamBrella is a cloud-based email security service for organizations and managed service providers that need to filter inbound and outbound mail. It covers spam, bulk mail, malware, phishing, spoofing and impersonation, with configurable filtering policies and quarantine review and release controls for users and administrators. It is aimed at teams that want protection and continuity around business email, rather than a standalone spam filter. Microsoft 365, Exchange Online and Google Workspace are among its listed integrations, and a REST API supports administration and reporting.
Threat handling spans AI-powered phishing detection, URL defense at scan time and click time, and malware and virus scanning for email content and attachments. The service also detects CEO fraud, impersonation and domain spoofing. Quarantine workflows give users and administrators review and release controls. Beyond filtering, continuity features include emergency inbox access, failover and message spooling during server outages; instant replay can recover deleted or lost messages for 30 days. These functions make SpamBrella relevant where protection against malicious mail and access to messages during an email outage matter together.
The broader feature set includes email archiving, encryption, DLP and compliance capabilities, plus integrations such as ConnectWise Manage, an Outlook add-in, and DKIM and DMARC. The service is cloud-deployed and lists email, phone, ticket and documentation support, with 24/7 support. According to the vendor's pricing information, buyers need to contact sales or partners; a 30-day trial is available, but there is no perpetual free plan. SpamBrella is worth considering for small, mid-market and enterprise teams seeking filtering alongside continuity and archiving. Teams requiring public upfront pricing or a non-cloud deployment should look elsewhere.
