Email authentication shouldn't require a security team. Yet for most small and mid-size businesses, protocols like DMARC, SPF, and DKIM remain confusing, fragile, and largely ignored — even as email fraud rises year over year.
Today we're launching SenderClarity, a DMARC monitoring and email authentication platform built from the ground up for organizations that don't have dedicated email security staff. It's the product we wish existed when we started helping businesses protect their domains over two decades ago.
The Problem We're Solving
Here's a statistic that should concern every business owner: fewer than 10% of domains have a published DMARC record, and only about 5% actively enforce it. That means the vast majority of organizations have no protection against email spoofing — anyone can send email that appears to come from their domain.
The consequences are real:
- Phishing attacks impersonating your business reach your customers and partners
- Brand damage when recipients receive fraudulent email from "your" domain
- Deliverability problems as inbox providers lose trust in unauthenticated senders
- Compliance gaps as Google, Yahoo, Microsoft, and PCI DSS 4.0 all now require or recommend DMARC
The barrier isn't awareness — most IT leaders know DMARC matters. A recent survey found that 40% of them say DMARC feels "too complex," and over half would rather hand it off to a specialist than manage it themselves.
We built SenderClarity to eliminate that complexity.
What SenderClarity Does
SenderClarity monitors your SPF, DKIM, and DMARC records around the clock and tells you — in plain English — what's happening, what needs attention, and exactly how to fix it.
Domain Health Scores
Every domain you monitor gets a health score calculated from five factors: DMARC compliance rate, policy strength, DNS record configuration, monitoring status, and trend direction. The score translates into a letter grade (A through F) that gives you an instant read on your email security posture.
This isn't a one-time scan. SenderClarity recalculates your health score continuously as new DMARC aggregate reports arrive and DNS changes are detected, so you always know where you stand.
Plain-English Guidance
Most DMARC tools dump raw XML reports on your lap and wish you luck. SenderClarity translates those reports into actionable insights anyone can understand.
When something needs attention — a new unauthorized sender, a broken SPF record, a DKIM alignment failure — you'll see a clear explanation of what happened, why it matters, and step-by-step instructions to fix it. No jargon, no guesswork.
Continuous DNS Monitoring
Your SPF, DKIM, DMARC, and BIMI records are checked on a regular schedule. If a record changes, goes missing, or develops a problem (like exceeding the SPF 10-lookup limit), SenderClarity detects it and alerts you immediately.
This catches issues that silently break email authentication: a developer who accidentally overwrites an SPF record, a third-party vendor who changes their sending infrastructure, or a DNS change that slips through without anyone noticing.
DMARC Aggregate Report Processing
SenderClarity receives and processes your DMARC aggregate reports automatically. Instead of parsing XML files from dozens of email providers, you get a clean dashboard showing:
- How many emails passed and failed authentication
- Which systems are sending on behalf of your domain
- Whether those senders are authorized or suspicious
- SPF and DKIM pass rates broken down by source
Guided Enforcement Journey
Moving from p=none (monitoring only) to p=reject (full protection) is the goal — but doing it carelessly can break legitimate email. SenderClarity tracks your readiness and tells you when it's safe to advance your policy, with a phased approach:
- Monitor — Collect data and identify all senders
- Quarantine — Start filtering unauthorized email to spam
- Reject — Block spoofed email entirely
At each stage, you'll see exactly what would happen if you tightened your policy, so there are no surprises.
Domain Readiness Checklist
When you add a domain, SenderClarity analyzes your existing DNS configuration and builds a personalized setup checklist. It detects your DNS provider and gives you provider-specific instructions for adding or updating records — whether you're on Cloudflare, GoDaddy, AWS Route 53, or anywhere else.
Notifications That Actually Reach You
This is where SenderClarity stands apart from every other DMARC tool we've used.
Most platforms send email notifications — which is ironic when you're trying to fix email authentication problems. SenderClarity delivers alerts where your team actually works:
Slack Integration
Connect your Slack workspace with a full OAuth integration. Choose exactly which channel receives alerts, and get formatted, actionable notifications the moment something changes. Your SPF record just broke? The alert lands in #it-ops with the exact DNS change that caused it and instructions to fix it.
Microsoft Teams Integration
The same rich notification experience, delivered to your Teams channels. For organizations running Microsoft 365, this means your email authentication alerts live alongside the rest of your IT operations workflow — no context switching required.
Email Alerts
Traditional email notifications are available too, of course. But with Slack and Teams as first-class destinations, you're not limited to email as your only alerting channel.
Weekly Summary Emails
Every week, SenderClarity sends a digest covering each domain's health score, compliance trends, new alerts, and any changes detected. It's a quick snapshot that tells you whether things are steady or need attention — without logging in.
Alert Types
SenderClarity monitors for a comprehensive set of conditions:
- SPF changes — Record added, modified, or removed
- DKIM changes — New selectors detected, selectors removed, records modified
- DMARC changes — Policy changes, record added or removed
- SPF lookup limit exceeded — Your SPF record has too many DNS lookups
- DMARC RUA missing — Your reporting address isn't configured correctly
- Compliance issues — Authentication failures crossing your threshold
Each alert carries a severity level (info, warning, or high) so you can focus on what matters most.
Free Tools for Everyone
You don't need a SenderClarity account to check your email authentication. We've built a set of free, public DNS analysis tools:
- SPF Checker — Validate your SPF record, count DNS lookups, and identify issues
- DKIM Checker — Verify DKIM selectors and key strength across multiple selectors
- DMARC Checker — Analyze your DMARC policy and reporting configuration
These tools are rate-limited but completely free, and they use the same DNS analysis engine that powers the full SenderClarity platform.
Enterprise Thinking, SMB Execution
CloudScope has been building enterprise analytics and messaging solutions for over 25 years. SenderClarity brings that enterprise-grade architecture to organizations that don't have enterprise budgets or dedicated security teams.
Here's what that means in practice:
Built for Teams
SenderClarity supports multiple users per account with role-based access. Account owners can invite team members with appropriate permissions — from read-only access for stakeholders to full administrative control for IT staff. Roles include Guest, User, Account Admin, and Account Owner.
Multi-Domain Management
Monitor all your domains from a single dashboard. Whether you have two domains or ten, you get a unified view of health scores, alerts, and compliance status across your entire portfolio. The account-level dashboard shows overall health, policy coverage percentage, and active alerts at a glance.
Compliance-Ready
SenderClarity helps you meet the email authentication requirements now mandated or recommended by:
- Google — Requires DMARC for bulk senders (enforced since 2024)
- Yahoo — Matching Google's requirements
- Microsoft 365 — Following with similar enforcement (2025)
- PCI DSS 4.0 — Recommends DMARC for organizations handling payment data
- NIST SP 800-177 — Federal guidelines for email authentication
Secure Architecture
The platform runs on Azure with JWT authentication, Azure AD/Entra ID integration for enterprise SSO, and encrypted connections throughout. Background processing uses Azure Service Bus for reliable, asynchronous operations. Your DMARC reports are processed securely and never shared.
