How it works

Set up in under 10 minutes

No software to install. One DNS TXT record and one Workspace admin setting and you're live.

Step 01

Connect your domain

Sign in with Google, then add a DNS TXT record to verify you own your domain. Usually live in under a minute.

Step 02

Set your outbound gateway

In Google Workspace Admin, set the outbound SMTP gateway to smtp.sendersafety.com. That's the entire technical setup.

Step 03

Define your rules

Add keywords, phrases, or regex patterns. Flag for review or block outright. Examples: "confidential", SSN patterns, competitor names.

Step 04

Monitor in real time

Every email is logged with sender, recipient, outcome, and which rule triggered. See exactly what's leaving your org.

Features

Built for compliance without complexity

Everything an IT admin or compliance team needs. Nothing they don't.

Rules engine

Keyword and regex scanning

Match on plain text or write custom regex patterns. Every rule is scoped to subject, body, or both — and set to flag or block.

Visibility

Full scan logs

Every email that passes through is logged with sender, recipient, timestamp, outcome, and which rule triggered — if any.

Performance

Zero delay for clean email

Emails that pass all rules are forwarded immediately via AWS SES. Your team won't notice any latency.

Privacy

Content never stored

Email bodies are never written to disk. Only a SHA-256 subject hash is logged. Your content stays yours — always.

Delivery

Transparent forwarding

Recipients see email from your team's real addresses, not ours. Sender Safety is completely invisible in the delivery chain.

Alerts

Policy violation notifications

When an email is blocked, the sender gets a clear bounce and the account admin receives an alert — with rule metadata only, never content.

We never store your email content. Ever.

Email bodies exist only in memory during the scan window and are discarded immediately after. We log metadata — not messages. This isn't a policy choice, it's an architectural one.

Use cases

Who uses Sender Safety

Any team that needs to know — and control — what's leaving their organization.

Financial advisors & brokers

FINRA and SEC regulations require supervising outbound communications. Sender Safety gives independent advisors enterprise-grade compliance at a fraction of the cost of Smarsh or Global Relay.

Legal & compliance teams

Block emails containing confidential case references, privileged information, or regulatory data before they reach unauthorized recipients.

HR departments

Prevent accidental disclosure of salary data, performance reviews, or employee PII outside the organization.

Finance teams

Catch emails containing account numbers, wire instructions, or financial projections before they reach the wrong inbox.

IT & security admins

Enforce email policy organization-wide without requiring individual user training or behavior change.

Small businesses

Protect client trust and your reputation with outbound filtering that used to cost enterprise money.
