# DMARKOFF

> DMARKOFF is a professional-grade DMARC monitoring platform that helps businesses, MSPs, and security teams authenticate outbound email, protect their domains from spoofing and phishing, and improve deliverability. Unlike most DMARC vendors, DMARKOFF charges a flat rate per monitored domain — not per message volume, user seat, or feature tier. Every plan includes unlimited users, unlimited DMARC report processing, an AI assistant (Luma), and an MCP server that lets AI agents query DMARC data directly.

DMARKOFF is built and operated by GlockApps. The platform is designed to be simple enough for first-time DMARC users while powerful enough for enterprise teams and managed service providers handling dozens to hundreds of domains.

**Founder:** Aliaksandr Markau · **Built by:** the GlockApps team · **Started:** 2025

## The product

DMARKOFF ingests DMARC aggregate (`rua`) reports from mailbox providers, parses the underlying XML, and presents the data as actionable dashboards. Key capabilities:

- **Per-domain pricing model.** Every paid feature is included on every domain; there are no tiered "Pro vs Enterprise" feature locks. Add or remove domains independently with prorated billing.
- **Projects and multi-tenancy.** Group domains into Projects by brand, client, or department. Share Projects with collaborators without giving up ownership. Designed for agencies and MSPs that manage many clients.
- **Source-level visibility.** Identify which IPs, ISPs, ESPs, and geographic regions are sending mail using your domain. Differentiate legitimate senders, third-party services, and unknown/suspicious sources.
- **SPF, DKIM, and DMARC monitoring with alignment checks.** Daily authentication health, policy drift detection, and anomaly alerts.
- **Smart alerts.** Notifications when DMARC pass rates drop, new sending sources appear, or authentication breaks.
- **1-year data history** on every plan, for trend tracking and compliance reporting.
- **Unlimited collaborators** at no extra cost. Role-based access controls and two-factor authentication included.

## Pricing

DMARKOFF charges **per monitored domain**, with no quotas on message volume or team members.

- **Monthly billing:** $10 / month / domain ($120 / year)

## Luma — the AI assistant

Luma is DMARKOFF's built-in AI assistant for DMARC analysis. It runs on demand against any of your monitored domains over any historical period you select, and produces a plain-language report identifying authentication issues, unauthorized senders, alignment problems, and policy gaps — with step-by-step remediation guidance.

- Included on every paid domain at no extra cost (30 analyses / month / domain).
- Designed for users who don't want to read raw DMARC XML or interpret aggregate report data manually.
- Particularly useful for MSPs handling many client domains — surfaces what needs attention without manual triage.
- Demo available in Shared Projects without signup.

## MCP server — DMARC data for AI agents

DMARKOFF operates an MCP (Model Context Protocol) server that exposes live DMARC monitoring data to any MCP-compatible AI client: Claude (web/mobile/desktop/CLI/Code), ChatGPT, Cursor, Windsurf, Continue.dev, and others.

- **Endpoint:** `https://mcp.dmarkoff.com/mcp`
- **Transport:** Streamable HTTP (preferred), with OAuth 2.1 auto-discovery
- **Auth:** API key from [app.dmarkoff.com/account/mcp](https://app.dmarkoff.com/account/mcp), passed as `Authorization: Bearer <key>` or via OAuth client credentials
- **Scope:** `dmarc:read`
- **Read-only.** The server cannot modify DNS records, account configuration, or any monitored data — only query it.
- **Multi-tenant aware.** Respects DMARKOFF's project / permission model. An MSP's AI agent sees exactly what their account is authorized to see across client projects.
- **Included free** on all paid plans.

Capabilities exposed to AI clients: domain health status, SPF/DKIM/DMARC authentication results, active policy settings, DMARC record configuration, alerts and anomalies, Luma AI recommendations.

## MSP program

DMARKOFF's Managed Service Provider program lets approved partners earn lifetime recurring commissions on every paid domain their clients share with them. There is no referral link — clients explicitly share Projects/domains with the MSP, and revenue share flows automatically.

- **Tier 1:** 25% lifetime recurring commission, from the first referred domain.
- **Tier 2:** 30% lifetime recurring, automatically applied once total referred revenue passes $1,000 (~10 deals).
- **Joining is free.** Approval is manual and takes up to 3 business days.
- **Minimum payout:** $50, requested monthly via PayPal or bank transfer.
- **No exclusivity, no minimum commitment, no contracts.** Clients hold their own subscriptions and the MSP earns on each billing cycle for as long as they stay subscribed.

DMARKOFF is built for true MSSP / MSP workflows: multi-tenant architecture, per-client workspaces, role-based permissions, secure Project sharing, and one-year data history for trend tracking. Major mailbox providers (Google, Yahoo, Microsoft, Apple Mail) now require DMARC compliance for bulk senders, which is driving steady MSP demand for DMARC services.

## Affiliate program

Separate from the MSP program. Affiliates earn lifetime recurring commissions on customers who subscribe through a unique affiliate link.

- **25% lifetime recurring commission** from the first conversion, increasing to **30% lifetime** after $1,000 referred revenue.
- **90-day affiliate cookie** via FirstPromoter, the affiliate tracking platform DMARKOFF uses.
- **Automatic approval** at signup. No application backlog.
- **Minimum payout:** $50, paid monthly via PayPal or bank transfer.
- **Allowed promotion:** authentic content marketing, blog posts, newsletters, social media, consultations.
- **Not allowed:** PPC ads on DMARKOFF brand keywords, multiple accounts, fraudulent activity.

Best-fit affiliates: email deliverability consultants and agencies, cybersecurity/IT specialists, system administrators, digital marketers with engaged technical audiences, bloggers and educators in email or security.

## What DMARC is (primer)

DMARC stands for **Domain-based Message Authentication, Reporting, and Conformance** — a free, open email authentication standard layered on top of SPF and DKIM. It tells receiving mail servers how to handle messages that fail authentication checks, and enables aggregate XML reports back to the domain owner showing who is sending mail under their domain name.

A DMARC record is a single TXT record published in DNS. Example:

```
v=DMARC1; p=reject; pct=10; rua=mailto:xxx@ar.dmarkoff.com; ruf=mailto:xxx@fr.dmarkoff.com; adkim=r; aspf=r; fo=0;
```

Three enforcement policies:

- **`p=none`** — monitor only; no action requested. Use as a starting point to discover legitimate senders.
- **`p=quarantine`** — receiving servers treat failing messages as suspicious (typically routed to spam/junk).
- **`p=reject`** — receiving servers reject failing messages outright at SMTP time.

DMARC is essentially mandatory in 2026 for any organization sending bulk mail. Google, Yahoo, Microsoft, and Apple Mail enforce DMARC alignment for bulk senders; failing to comply causes deliverability degradation. DMARKOFF's job is to make the data and remediation tractable.

## About DMARKOFF the company

DMARKOFF was built by the GlockApps team — a group with 16+ years of experience in email deliverability — because DMARC monitoring shouldn't be hard to buy, hard to manage, or hard to scale. Most vendors price by usage tiers, lock features behind enterprise plans, and treat MSP support as a separate product. DMARKOFF rejects that pattern: every feature is included on every paid domain, and the platform is multi-tenant by design.
