About SpamHero
What is SpamHero?
SpamHero is a cloud-based email filtering service that protects your domain from spam, viruses, and malware. It sits in front of your mail server and filters inbound emails before they reach your users, using over 22 million filter rules and tracking more than 100 million senders.
What problem does it solve?
SpamHero reduces the noise and security risk of email-borne threats. It handles spam and virus filtering, domain-wide filtering policies, custom rule creation, and even geographic and attachment-type filters, so you can control exactly what gets through.
Who is it for (and who is it not for)?
SpamHero is designed for businesses, IT administrators, and managed service providers (MSPs) that need robust, domain-based email protection without per-user pricing. It's not ideal for individuals needing a simple personal email filter—it's built for domains with multiple mailboxes, offering unlimited email addresses and aliases.
Real use cases
A company with 50 employees wants to centralize spam filtering, set custom rules for attachments, and get daily reports. An MSP manages multiple client domains and needs a reseller-friendly plan with shared or individual quarantine options. A business with occasional high-volume email spikes can use the fail-safe design and overage billing protection.
Key features
- Inbound filtering — Blocks spam, viruses, and malware before they hit your mail server.
- Unlimited email addresses — Filter all mailboxes on your domain without per-user costs.
- Domain-wide policies — Apply consistent filtering rules across your entire domain.
- Quarantine management — Individual and shared quarantine boxes with view, recover, or re-deliver options.
- Reporting — Schedule hourly, daily, or weekly reports to monitor email activity.
- Fail-safe design — Distributed cloud setup and destination fail-over MX support for high availability.
