This API verifies an email address. It checks the syntax, the domain, and the mail servers, then tests whether the mailbox itself can be confirmed. It also flags disposable addresses, free providers, role accounts such as info or support, and domains that accept every recipient. A score and a risk level summarize the result, and a suggestion appears when the domain looks mistyped. Use it on signups, lead capture, and list cleaning. No message is sent to the address.
The API performs a comprehensive set of checks including syntax validation, domain verification, MX record lookup, SMTP mailbox testing, identification of disposable email addresses, detection of catch-all domains, flagging of role-based accounts (e.g., info@, support@), identification of free provider emails, and a risk score assessment.
The API is ideal for real-time validation during user sign-ups and lead capture forms to ensure data accuracy. It is also highly effective for cleaning existing email lists to remove invalid or problematic addresses, thereby improving deliverability and reducing bounce rates.
The API returns a detailed result for each email address, including a risk score and a corresponding risk level. It also provides specific flags indicating if the email is disposable, a role account, from a free provider, or from a catch-all domain. Additionally, it offers suggestions if the domain appears to be mistyped.
By verifying email addresses in real-time, the API prevents invalid or fake emails from entering your systems. This leads to cleaner databases, higher deliverability rates for marketing campaigns, reduced operational costs associated with managing bounced emails, and a better experience for legitimate users by ensuring their communications reach them.
No, the Valid Email Detection API does not send any messages or emails to the address being verified. All checks are performed server-side without any external communication to the mailbox itself, ensuring privacy and avoiding any potential disruption to the user.
