Frequently asked questions

An invalid email address is one that cannot receive emails due to various reasons: it may have syntax errors, the domain might not exist, the mailbox might be full or deactivated, or it could be a disposable/temporary email address designed for one-time use.

Invalid emails can severely impact your email campaigns in multiple ways: they increase bounce rates, damage your sender reputation, waste marketing budget, risk getting your domain blacklisted, and lower your email deliverability rates. This can lead to legitimate emails not reaching your customers inboxes.

Email validation is the process of verifying whether an email address is valid, deliverable, and safe to send emails to. It helps prevent bounces, protect sender reputation, and maintain a clean email list.

Our API performs multiple checks including syntax validation, domain verification, mailbox existence check, and disposable email detection. It returns detailed results about the emai's validity and potential risks.

Validating emails helps reduce bounce rates, protect sender reputation, improve deliverability, and save costs on email campaigns by ensuring you only send to valid addresses.
