What is Email Validation?

Email validation is the process of verifying that an email address is valid, active, and safe to send emails to. It helps reduce bounce rates, protect your sender reputation, and ensure your messages reach real people.

15 Checks We Perform

1. Syntax Validation

Verifies the email follows RFC 5321 standards for email format. Checks for proper structure: local-part@domain.tld

2. DNS Validation

Confirms the domain exists and has valid DNS records configured.

3. MX Record Check

Verifies the domain has mail exchange (MX) records configured to receive emails.

4. SMTP Verification

Connects to the mail server to verify the mailbox actually exists without sending an email.

5. Disposable Email Detection

Identifies temporary or disposable email addresses from services like Mailinator, TempMail, etc.

6. Role Account Detection

Detects role-based emails (info@, support@, admin@) which often have lower engagement rates.

7. Free Provider Detection

Identifies emails from free providers (Gmail, Yahoo, Outlook) vs. business domains.

8. Typo Detection

Catches common typos in popular domains (gmial.com → gmail.com).

9. Catch-All Detection

Identifies domains configured to accept all emails regardless of mailbox existence.

10. Spam Trap Detection

Flags known spam trap addresses that can damage your sender reputation.

11. Accept-All Detection

Detects mail servers that accept all emails but may not deliver them.

12. Gibberish Detection

Identifies randomly generated email addresses that are unlikely to be real.

13. Domain Age Check

Verifies domain registration age to identify newly created domains.

14. Greylisting Detection

Identifies temporary delays in email acceptance by the receiving server.

15. Reachability Score

Provides an overall deliverability score: safe, risky, invalid, or unknown.

Why Validate Emails?

Reduce Bounce Rates

Invalid emails bounce, damaging your sender reputation. Validation ensures you only send to real addresses.

Protect Sender Reputation

High bounce rates can get your domain blacklisted. Keep your reputation clean with validation.

Save Money

Don't waste credits sending to invalid addresses. Validate first, send smarter.

Improve Deliverability

Clean lists mean better inbox placement and higher open rates.

Prevent Fraud

Block disposable and temporary emails used for fraud and fake signups.

Better Analytics

Accurate email lists mean more reliable metrics and insights.

How Email Validation Works

Format Check

First, we verify the email follows proper syntax rules defined in RFC 5321.

Domain Verification

Next, we check if the domain exists and has valid DNS records.

MX Record Lookup

We query DNS for MX records to find the mail servers for the domain.

SMTP Handshake

We connect to the mail server and verify the mailbox exists without sending an email.

Additional Checks

Finally, we run checks for disposables, role accounts, spam traps, and more.
