Frequently Asked Questions

Q: How accurate is the validation? A: Basic validation (syntax + DNS + disposable) is highly accurate. SMTP verification adds additional confidence but may have false negatives due to greylisting.

Q: Can I validate emails in real-time? A: Yes, use the synchronous API endpoint for real-time validation. Response time is typically under 1 second per email.

Q: What's the difference with and without SMTP check? A: Without SMTP, we verify the domain can receive emails. With SMTP, we actually connect to the mail server to verify the specific mailbox exists.

Q: How often is the disposable domain list updated? A: The list is updated with each actor version release, typically incorporating new disposable domains found in the wild.
