About Email Validation & Verification

Our email validator performs two types of checks:

1. Syntax Validation (RFC 5322):

  • Correct format (local@domain.tld)
  • Local part length (max 64 characters)
  • Domain length (max 255 characters)
  • Valid characters and structure
  • No consecutive dots or invalid patterns

2. Email Verification:

  • DNS MX record check (can domain receive emails?)
  • Domain existence verification
  • Mail server availability

Note: The verification checks if the domain can receive emails by checking DNS MX records. It does not verify if the specific mailbox exists (this would require sending a test email, which most mail servers block for security reasons).
