How to Fix DMARC Issues Automatically (No DNS Expertise Required)

The Problem with Manual DNS Fixes
You just ran a domain scan and found that your DMARC record is missing, your SPF record has too many lookups, or your DKIM is not properly aligned. You know these are important issues. But now what?
For most organizations, the journey from "knowing the problem" to "fixing the problem" is where things stall. Here is why:
DNS is intimidating
DNS record syntax is arcane. A single misplaced semicolon, a missing space, or a wrong value can break email delivery entirely. For non-specialists, editing DNS records feels like defusing a bomb.
Every provider is different
Cloudflare's DNS dashboard looks nothing like GoDaddy's, which looks nothing like Route 53's. The field names differ (some say "Host," others say "Name," others say "Record"), the TTL defaults are different, and the proxy settings add confusion.
Verification takes time
After making a DNS change, you need to wait for propagation (minutes to hours), then verify the change took effect, then check that it did not break anything else. This feedback loop is slow and frustrating.
It requires multiple teams
The security team identifies the issue, but the DNS is managed by IT ops, who need approval from the domain owner, who is in a different department. A five-minute fix becomes a two-week ticket.
The result? Critical security issues sit unfixed for weeks or months. According to industry data, the average time from DMARC issue detection to resolution is over 30 days for organizations without automated tools.
What Guided Fix Means
An guided fix engine is software that can detect a problem, determine the correct fix, preview the change for human approval, apply the fix via the DNS provider's API, and then verify the fix took effect. It turns a multi-step, multi-team process into a single-click operation.
The key word is "autonomous," not "automatic." The engine handles the entire workflow, but the human always reviews and approves before any change goes live. Think of it as an AI co-pilot for your DNS — it does the work, you make the decision.

How Vysiro's Fix Engine Works
Vysiro's fix engine follows four steps to resolve DMARC, SPF, DKIM, and other DNS-based security issues:
Provider Detection
When you scan a domain, Vysiro automatically detects your DNS provider by analyzing NS records. It identifies whether you are on Cloudflare, Route 53, DigitalOcean, GCP DNS, GoDaddy, Namecheap, or 15+ other providers. This determines whether automatic API-based fixes are available or whether guided fixes will be used.
Fix Planning
For each issue found, the engine generates the correct DNS record value. For example, if DMARC is missing, it generates:
Preview & Approve
Before any change is applied, you see a full diff preview showing exactly what will change:
- (no DMARC record exists)
+ _dmarc.yourdomain.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com; fo=1"
You review the change, confirm it is correct, and click "Apply Fix." Nothing happens until you explicitly approve.
Apply & Verify
Once approved, the fix engine calls the DNS provider's API to create or update the record. After the change is applied, Vysiro re-scans the domain to verify the fix took effect and the issue is resolved. The entire process typically completes in under 60 seconds.
Supported DNS Providers
Vysiro supports two modes of fix delivery depending on your DNS provider:
Auto-Fix (API-Based)
Connect your account via OAuth or API key. Vysiro applies fixes directly through the provider's API after your approval.
- •Cloudflare (OAuth — available now)
- •AWS Route 53 (coming soon)
- •DigitalOcean DNS (coming soon)
- •Google Cloud DNS (coming soon)
Guided Fix (Instructions)
For providers without API integration, Vysiro generates step-by-step instructions with copy-paste DNS record values specific to your provider's UI.
- •GoDaddy
- •Namecheap
- •Hover
- •Google Domains (Squarespace)
- •And 10+ more providers
Both modes generate the exact same correct DNS record values. The only difference is whether the record is applied via API (automatic) or manually by you following the instructions (guided).
Guided Fix vs Guided Fix
| Feature | Guided Fix | Guided Fix |
|---|---|---|
| How it works | Copy-paste instructions for your DNS provider | API-based fix applied after your approval |
| DNS provider access needed | Manual login to DNS dashboard | OAuth connection (one-time setup) |
| Time to fix | 5-15 minutes | Under 60 seconds |
| Error risk | Manual copy-paste can introduce errors | Near zero (API handles syntax) |
| DNS expertise needed | Minimal | None |
| Verification | Manual re-scan needed | Automatic verification after apply |
| Available on | All plans | Paid plans (+$5 per fix on some tiers) |
Real Example: Fixing a Missing DMARC Record
Let's walk through a real scenario. You scan example.com and Vysiro reports: "No DMARC record found." Here is what happens next with autonomous fix:
Step 1: Scan Result
DMARC: FAIL - No DMARC record found at _dmarc.example.com
Impact: Your domain can be spoofed in phishing emails
Fix available: Create DMARC record (guided fix ready)
Step 2: Click "Fix This Issue"
Vysiro detects that example.com uses Cloudflare (from NS records) and that you have connected your Cloudflare account. It generates the fix:
# Proposed DNS Change
+ ADD TXT record at _dmarc.example.com
+ Value: "v=DMARC1; p=none; rua=mailto:dmarc@example.com; fo=1"
+ TTL: 3600
Step 3: Review and Approve
You review the proposed record, confirm the rua email address is correct, and click "Apply Fix." Vysiro calls the Cloudflare API to create the TXT record.
Step 4: Verification
DMARC: PASS - Record found: v=DMARC1; p=none; rua=mailto:dmarc@example.com; fo=1
Fix verified successfully in 12 seconds
Total time from scan to verified fix: under 30 seconds. No DNS dashboard visited. No record syntax memorized. No propagation anxiety. The same process applies to missing SPF records, incorrect DKIM selectors, missing MTA-STS policies, and other DNS-based issues. You can start by checking your current configuration with our free tools: DMARC Checker, SPF Validator, and DKIM Verifier.
