Confidence Score Breakdown

The Email Validator on TechConverter.me helps you maintain a clean, deliverable email list, reduce bounce rates, and protect your sender reputation — all with instant, multi-level validation for individual addresses or bulk lists.

Examples

Example 1: Syntax Validation

The validator checks that an address follows RFC 5321/5322 rules. Examples of valid and invalid syntax:

  • user@example.com — valid
  • user.name+tag@example.co.uk — valid (plus addressing and subdomains allowed)
  • user@[192.168.1.1] — valid (IP address domain)
  • user@example — invalid (no TLD)
  • @example.com — invalid (missing local part)
  • user @example.com — invalid (space in local part)
  • user@@example.com — invalid (double @)
  • user..name@example.com — invalid (consecutive dots in local part)

Example 2: Domain and MX Record Validation

A syntactically valid address can still be undeliverable if the domain has no mail servers. The validator performs a DNS lookup:

Email: user@nonexistent-domain-xyz123.com
Result: INVALID

Reason: Domain does not exist (NXDOMAIN)
DNS lookup: no A record, no MX record found
Deliverability: 0% — address cannot receive email
Email: user@website-with-no-email.com
Result: RISKY

Reason: Domain exists but has no MX records
DNS lookup: A record found (website exists), no MX record
Deliverability: low — domain is not configured to receive email
Email: user@gmail.com
Result: VALID

MX records found:
  10 alt1.gmail-smtp-in.l.google.com
  20 alt2.gmail-smtp-in.l.google.com
Deliverability: high

Example 3: Disposable Email Detection

The validator identifies addresses from temporary email services:

Email: temp123@mailinator.com
Result: DISPOSABLE

Service: Mailinator (known temporary email provider)
Recommendation: reject or flag for manual review
Risk: user likely avoiding real email verification
Email: throwaway@guerrillamail.com
Result: DISPOSABLE

Service: Guerrilla Mail
Recommendation: block if your use case requires real email addresses

Common disposable domains the validator detects include mailinator.com, guerrillamail.com, 10minutemail.com, tempmail.com, throwam.com, and hundreds of others.
