What makes your email validation thorough?
We perform multiple verification checks including syntax validation, MX records lookup, SMTP connection, and mailbox verification for comprehensive email validation.
How do you handle catch-all domains?
We identify catch-all domains and flag them separately. While these domains accept all emails, we can't verify individual mailboxes.
Can I validate emails at signup in real-time?
Absolutely! Our API responds in under 2 seconds, making it perfect for real-time form validation during user registration.
Do you support bulk email validation?
Yes! Upload CSV files with up to 1 million emails. We'll validate them in parallel and return results within hours.
How can I test email validation before committing?
Try our [free email validator tool](/tools) instantly, or use the free tier with 1,000 validations/month to integrate into your signup flow.
Can you detect disposable email addresses?
Yes! Our validation includes disposable email detection, identifying temporary email services like 10minutemail and tempmail to prevent fake signups.
Can I validate emails in bulk?
Yes, our paid plans support high-volume validation with generous rate limits. Bulk list cleaning? You can run thousands of parallel requests for fast processing.
Do you detect email typos?
Yes! Our API detects common typos in email domains (like gmial.com instead of gmail.com) and sets the hasTypo flag to true. You can then prompt users to verify their email address.
How do you identify role-based emails?
We detect role-based addresses like info@, support@, admin@ which are often shared mailboxes. This helps you segment your email lists appropriately.
Is SMTP verification safe for my server reputation?
Yes! We use dedicated validation infrastructure and best practices to avoid being flagged as spam. Our SMTP checks are non-intrusive and respect rate limits.
