Email verification tool is software or an online service that checks the validity and deliverability of email addresses by checking syntax, domain, and mailbox validation.

An email verification tool uses advanced algorithms to quickly and accurately check email addresses for validity, bounce rates, and spam traps. It is a more efficient and reliable method compared to manual verification.
