Quarantine DigestHeld mail is listed in the user’s daily summary. They release what’s legitimate with one click.

Mail that fails authentication doesn’t reach your customers, and nobody files a ticket to get a false positive back.

Built for hosts running mail at scale

Multi-tenant by design. One MX record protects every domain across your fleet, with per-domain controls when you need them.
Multi-layered threat detection

Spam, phishing, and malware identified through multiple independent detection engines — not a single rule set that breaks when attackers adapt.

End-user self-service

Customers manage their own safelists, blocklists, and false-positive recovery — without filing a ticket with your support team.

Authentication standards built in

SSL/TLS, SPF, DKIM, and DMARC enforced inline. Mail that fails authentication doesn’t reach your customers.

30-Minute human response, 24/7

Real engineers, not chatbots, when something needs attention.

Intelligent quarantine™

False positives are the support-ticket killer in inbound filtering. Intelligent Quarantine™ gives senders a self-service release link instead of silently routing to a junk folder — so legitimate mail gets through and your support team doesn’t have to investigate.

Log search

Find any message in seconds. Support agents can answer “where’s my email?” tickets without escalating to engineering — and customers can search their own mail history through the same interface.
