📚 Email Verification Documentation
Understand the results and metrics provided by the Webyverse Email Verifier.
Results Overview
The email verification results provide comprehensive insights into the validity and deliverability of the email address you entered. Our advanced verification system performs multiple checks to ensure accuracy and reliability.
Detailed Results Breakdown
Field | Description | Impact |
---|---|---|
Email Address | The complete email address that was verified, displayed exactly as entered | Reference |
Format Valid | Indicates whether the email address follows RFC 5322 standards (contains "@", valid domain structure, proper character usage) | Critical |
Domain Status | Shows if the domain associated with the email is active, reachable, and properly configured | Critical |
MX Records | Indicates whether the domain has valid Mail Exchange records that allow it to receive emails | Critical |
SMTP Status | Shows if the SMTP server for the domain is reachable and can accept email connections | High |
Reputation Score | A comprehensive score from 0-100 based on multiple deliverability factors and domain reputation | High |
Deliverability Status | Overall assessment: "Deliverable" or "Undeliverable" based on all verification checks | Critical |
Associated Domain | The domain portion of the email and its website status (if applicable) | Medium |
Analysis Duration | Time taken to complete the verification process (typically 1-5 seconds) | Low |
Understanding the Reputation Score
The reputation score is a crucial metric that helps determine the deliverability of the email address. Our algorithm considers multiple factors to calculate this score:
90-100 Points
Excellent
The email address is highly likely to be deliverable with no issues detected.
70-89 Points
Good
The email address is likely deliverable, but minor issues may exist.
50-69 Points
Average
The email address may have deliverability issues that need attention.
0-49 Points
Poor
The email address is likely undeliverable and should be avoided.
- Format Validation (+30): Proper email format structure
- Domain Health (+20): Active and properly configured domain
- MX Records (+20): Valid mail exchange records
- SMTP Response (+20): Mail server accessibility
- Reputation Factors (+10): Domain reputation and history
Common Issues Explained
During the verification process, several common issues may be detected. Understanding these helps you make informed decisions:
🚫 Disposable Email Detected
What it means: The email address belongs to a temporary email service (like 10minutemail, tempmail, etc.)
Impact: These addresses are often used for spam or temporary registrations and may become invalid quickly.
Recommendation: Avoid using for important communications or require alternative contact methods.
📭 No MX Records Found
What it means: The domain does not have Mail Exchange records configured in its DNS.
Impact: Without MX records, the domain cannot receive emails at all.
Recommendation: Contact the domain owner or choose a different email address.
🔌 SMTP Server Unreachable
What it means: The mail server for the domain could not be contacted during verification.
Impact: May indicate temporary server issues or firewall restrictions.
Recommendation: Try verification again later or verify through alternative means.
🌐 Custom Domain Without Website
What it means: The domain is custom but doesn't have an active website associated with it.
Impact: May indicate a legitimate but minimal online presence.
Recommendation: Consider the context - this may be normal for personal domains.
Technical Analysis Details
🔧 What We Check
Check Type | Method | Purpose |
---|---|---|
Format Validation | RFC 5322 pattern matching | Ensures email follows standard formatting rules |
Domain Resolution | DNS A/AAAA record lookup | Verifies the domain exists and is reachable |
MX Record Check | DNS MX record query | Confirms the domain can receive mail |
SMTP Handshake | Direct server connection | Tests mail server availability and response |
Disposable Detection | Known provider database | Identifies temporary email services |
📊 Response Time Expectations
- Fast (0-2 seconds): Cached results or simple validation
- Normal (2-5 seconds): Full verification with all checks
- Slow (5-10 seconds): Slow DNS/SMTP responses
- Timeout (10+ seconds): Server issues or network problems
Best Practices for Email Verification
✅ Do This
- Verify emails in real-time during registration
- Use verification for critical communications
- Implement double opt-in for newsletters
- Regularly clean your email lists
- Respect verification results and user privacy
❌ Avoid This
- Don't store unverified emails long-term
- Don't ignore high-risk verification results
- Don't verify the same email repeatedly
- Don't use disposable emails for important accounts
- Don't bypass verification for convenience
- Segment by verification status: Keep verified and unverified emails separate
- Set verification thresholds: Define minimum scores for different use cases
- Monitor bounce rates: Track delivery performance over time
- Update regularly: Re-verify old email addresses periodically
- Provide feedback: Let users know why their email was rejected
Integration Examples
📝 Understanding API Responses
When using our verification service programmatically, you'll receive a JSON response similar to this:
{ "email": "user@example.com", "format_valid": true, "deliverability_status": "Deliverable", "reputation_score": 85, "mx_records": { "has_mx": true, "records": ["mail.example.com"] }, "smtp_check": { "valid": true, "message": "SMTP server reachable", "server": "mail.example.com" }, "issues": [], "is_disposable": false, "associated_domain": "example.com", "domain_status": "Custom domain with website", "analysis_duration": 2.3 }
🔍 Key Response Fields
- deliverability_status: Primary field to check - "Deliverable" or "Undeliverable"
- reputation_score: Numeric confidence score (0-100)
- issues: Array of specific problems found
- analysis_duration: Processing time in seconds
Troubleshooting Common Problems
Why is my valid email showing as invalid?
- Typos: Check for spelling errors in the email address
- Recent changes: Domain DNS changes can take up to 48 hours to propagate
- Server issues: Temporary mail server problems affect verification
- Firewall restrictions: Some servers block verification attempts
What if verification takes too long?
- Normal processing: Most verifications complete within 5 seconds
- Slow DNS: Some domains have slower response times
- Network issues: Connectivity problems can cause delays
- Try again: Re-run verification if it times out
