IP-scoped + DMARC-first
Government & Public Sector

Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.

  • IP allowlist at authentication
  • DMARC-first per domain
  • Full audit log and role-based access
  • Per-department tenancy
The pain

What you deal with today.

Public-sector mail has to be delivered reliably, but every credential leak, every operator action, and every DMARC failure is a headline waiting to happen. You need scoping (only your infrastructure can send), auditability (every operator action logged), and DMARC-first configuration by default.

How sendrules answers

What changes when you route through us.

sendrules scopes every rule's credentials to your CIDR ranges at the authentication step, logs every configuration change and every message action in the audit trail, and treats DMARC as a first-class citizen — aggregate report ingestion, source classification, and compliance per sending domain. Per-tenant isolation means no citizen data ever crosses a departmental boundary.

The four capabilities

Feature per pain, not the other way round.

IP allowlist at authentication

Every credential can be scoped to a CIDR list at the authentication step. A leaked password from outside your infrastructure cannot be used to send.

Read more →

DMARC-first per domain

Hosted aggregate report ingestion, sources classified, and compliance surfaced per sending domain. A DMARC record generator ships alongside, so departments new to DMARC start with a working policy.

Read more →

Full audit log and role-based access

Every operator action logged — who, when, what. Per-role permissions on every action. Regulator-ready without an export pipeline to build.

Read more →

Per-department tenancy

Each department is a tenant with its own credentials, its own domain, and its own DMARC posture. No shared credentials across departmental boundaries.

Where it lands

Concrete scenarios you can wire in this week.

  • Citizen notifications with automatic failover so a single provider outage doesn't delay urgent correspondence
  • Credentials scoped by IP allowlist to the department's production CIDR ranges — leaked passwords cannot send from outside
  • DMARC compliance per department domain with sources correctly classified as Known, Unknown, or Forwarded
  • Audit log covering every operator action — configuration changes, credential rotation, and rule edits
  • Multi-department tenancy so no data ever crosses a departmental boundary, even in aggregate reporting
