FAQ

Q: What validation checks are performed?

A: We check email syntax validity using regex patterns, verify the domain has valid MX or A records using DNS queries, and compare against a comprehensive list of known disposable email domains.

Q: Can I validate emails in bulk?

A: Yes! Upload a CSV file with an "email_address" column and validate thousands of emails simultaneously. Free tier allows 50 emails per upload, while Pro accounts can validate up to 2,000 emails at once.

Q: What is a disposable email?

A: Disposable emails are temporary email addresses from services like Mailinator, 10MinuteMail, or GuerrillaMail. These services allow users to receive emails without creating a permanent account, often used to avoid spam or bypass registration requirements.

Q: Why does my email show NO_MX status?

A: This means the domain doesn't have MX (Mail Exchange) records configured in DNS. Without MX records, the domain cannot receive emails. This could indicate a typo, an inactive domain, or a domain not configured for email.

Q: How accurate is the validation?

A: Our validation checks syntax, DNS records, and disposable domain lists with high accuracy. However, it cannot guarantee that a specific email address is actively monitored or that the mailbox isn't full. It validates that the email format is correct and the domain can receive mail.

Q: What's the difference between INVALID and NO_MX?

A: INVALID means the email syntax is incorrect (e.g., missing @, invalid characters). NO_MX means the email syntax is valid, but the domain cannot receive emails because it lacks proper DNS records.

Q: Can I export my validation results?

A: Yes! Pro users can download results in CSV or JSON format for easy integration with other tools, CRM systems, or marketing platforms.

Q: How often is the disposable domain list updated?

A: Our disposable domain database is regularly updated with new temporary email services as they emerge to ensure comprehensive detection.

Q: What happens to my uploaded CSV files?

A: CSV files are processed in memory and not permanently stored on our servers. Pro users have the option to save validation results to their account history for future reference.

Q: Is there an API available?

A: Yes! Ultimate tier subscribers have access to our REST API for programmatic email validation. Contact support for API documentation and access credentials.
