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 AUTH
  • DMARC-first per domain
  • Full audit log + RBAC
  • 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 restricts every rule's credentials to your CIDR ranges at the SMTP AUTH step, logs every configuration and message action in the audit log, and treats DMARC as a first-class citizen — aggregate ingestion, source classification, compliance % per domain. Per-tenant isolation means no citizen data ever crosses departmental boundaries.

The four capabilities

Feature per pain, not the other way round.

IP allowlist at AUTH

Every credential can be scoped to a CIDR list at the SMTP AUTH step. A leaked password from outside your infrastructure cannot authenticate.

DMARC-first per domain

Hosted rua ingestion, sources classified, compliance % surfaced per sending domain. Ship a DMARC record generator too.

Read more →

Full audit log + RBAC

Every operator action logged (who, when, what). Per-role permissions on every action. Regulator-ready.

Read more →

Per-department tenancy

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

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 mail
  • IP allowlist at AUTH scoping every credential to the department's production CIDR
  • DMARC compliance % per department domain with sources correctly classified (Known / Unknown / Forwarded)
  • Audit log covering every operator action — configuration changes, credential rotation, rule edits
  • Multi-department tenancy so no data crosses departmental boundaries

Other segments with similar shapes.

Marketing Agencies & MSPs

Verify every recipient in-line. Then parse every autoresponder reply for the person actually handling the account.
