Everything you need to verify email addresses

Multi-layer validation that catches invalid emails before they hurt your metrics.

Syntax Validation

Checks format according to RFC 5322 standards — local part, @ symbol, domain.

✓ Why it matters: Catch typos before they enter your database

Domain MX Lookup

Verifies domain has valid mail exchange (MX) records configured.

✓ Why it matters: No MX = no email delivery possible

Disposable Detector

Identifies temporary email services like 10minutemail, Guerrilla Mail.

✓ Why it matters: Prevent fake signups and spam registrations

Role Account Detection

Flags admin@, info@, sales@ — generic role-based addresses.

✓ Why it matters: Role accounts often have low engagement

Typo Correction

Suggests fixes for common domain typos (gmail.cmo → gmail.com).

✓ Why it matters: Recover lost leads from common typos

Bulk Email Validation

Upload CSV and validate up to 1,000 emails per batch.

✓ Why it matters: Clean entire email lists before campaigns

❓ Email validation FAQs

Everything you need to know about email verification

How accurate is your email validation?+
Our validation combines syntax checking, domain MX record verification, and disposable email detection, achieving 98.7% accuracy on valid/invalid determination. We don't perform SMTP "ping" checks to respect privacy and rate limits.
Do you store the emails I validate?+
No. Privacy is our priority. Emails are processed in real-time and never stored in our databases. You can validate sensitive business emails with complete confidence.
Can I validate a list of emails in bulk?+
Yes. Upload a CSV file with up to 1,000 emails. Our system will process them and provide a downloadable report with valid/invalid status for each address.
What is a disposable email address?+
Disposable emails are temporary addresses from services like 10minutemail, Guerrilla Mail, or Mailinator. They're often used for spam or fake signups. Our tool detects these automatically.
Do you check if the mailbox actually exists?+
We verify domain MX records to ensure the domain can receive email. We do not perform SMTP "RCPT TO" verification as this can be considered intrusive and violates some email provider policies.
Can I integrate this into my website form?+
Yes. We offer a free REST API that you can call from your signup forms, checkout pages, or any other frontend/backend application. The free tier includes 1,000 requests/day.
What's the difference between validation and verification?+
Validation checks syntax, domain, and MX records. Verification (or "deep verification") attempts to connect to the mail server. We focus on validation for privacy and compliance reasons.
Is there a limit on free checks?+
For single email checks, there's no limit. For bulk CSV uploads, we offer 5 free batches per day (up to 1,000 emails each). Higher volumes are available via our paid plans.
