Verifies email format follows RFC 5321 and RFC 5322 standards. Catches obvious errors like missing @ symbols or invalid characters.
Checks if the domain exists and has valid MX (mail exchange) records configured for receiving emails.
Predicts whether the specific mailbox exists and can actually receive messages. Most important check for deliverability.
Identifies role-based addresses (admin@, support@, info@) which typically have lower engagement rates.
Detects disposable or temporary email services that could negatively impact your sender reputation.
Identifies randomly generated email addresses that are likely fake or created by bots.
Invalid emails hurt your sender reputation and waste marketing budget
Email validation is the process of verifying that an email address is valid, deliverable, and safe to use. Our tool uses AWS SES Email Validation API to perform 6 comprehensive checks including syntax validation, DNS verification, mailbox existence check, role address detection, disposable domain check, and random pattern detection. This helps you maintain a clean email list and protect your sender reputation.
Our validator is powered by AWS SES Email Validation API, one of the most accurate email validation services available. It provides a confidence verdict (HIGH, MEDIUM, LOW) based on all 6 validation checks. High confidence results are typically 95%+ accurate for deliverability prediction. However, no validator can be 100% accurate due to limitations like catch-all mailboxes and privacy-protected domains.

Syntax check verifies the email follows proper formatting rules (like having an @ symbol), while mailbox check actually verifies if that specific email address exists and can receive messages. An email can have perfect syntax but still be invalid if the mailbox doesn't exist. Mailbox verification is the most important check for ensuring deliverability.
Role addresses (like admin@, support@, info@) are generic mailboxes typically managed by multiple people or departments. They tend to have lower engagement rates, higher unsubscribe rates, and are more likely to mark emails as spam. While not always bad, they're generally less valuable for marketing campaigns than personal email addresses.
