Safe message review without the back and forth
When messages are held, users are notified on a customizable schedule. A safe preview and one-click release or block means they can handle it themselves—no ticket required.
Take control of what leaves your clients' environments
Bundled with CloudFilter, SafeSend adds advanced outbound content controls and compliance tools. Sensitive data stays in, and your clients' sending habits stay visible.
DLP rule templates
Pre-built templates make it fast to create rules for risky content types. Admins have full control over what happens when one is triggered.
Instant blocking notifications
When outgoing emails are blocked for policy violations, the sender is immediately notified that the message was held and why.
Compliance footers
Required legal disclaimers can be added to outgoing messages at the account, domain, user group, or individual user level.

A mobile-first admin console with the depth of control other gateways simply can't match without feature bloat.
Full Audit Trail
Full visibility into every admin action for accountability when multiple techs are managing the same environments.
