Its main purpose is to help to filter "real" customers from abusers, increase response and success rates of your email campaigns and avoid getting into spam filters. Our service allows you to instantly verify email address: perform a syntax check, verify the existence of the domain and mail server records. It also provides the following information about the email address: if it is free, disposable, role, etc.
Email validation made easy. Simple REST API for checking the email format and predict deliverability. Validation is done via format validation, general DNS check, MX records check, social signals and checks for various negative patterns (eg. [email protected]) . Also checks if the email is disposable or a "spam trap". "Deep" SMTP validation is coming soon.
Email is essential to pretty much every application. Consumers use their email addresses as login for applications and expect to receive notifications and messages. Use email validation APIs to block account creation with temporary or fake email addresses. Use email APIs to send transactional emails such as password resets or notifications and marketing emails such as newsletters.
