Frequently Asked Questions
What is email validation?
Email validation checks if an email address is properly formatted, if the domain exists and accepts emails (MX records), and whether it is a known disposable or spam address.
Can this tool check if an inbox exists?
No. Checking if a specific inbox exists requires SMTP verification, which many providers block. This tool validates format and domain configuration.
What is a disposable email address?
Disposable emails (like Mailinator, Guerrilla Mail) are temporary addresses. If you are running a platform, blocking disposable emails improves data quality.
