Email validation service  is a platform or tool that helps email marketers clean their list of invalid, fake, disposable and other non-reachable email addresses to ensure that their campaigns are successfully delivered to the right subscribers. Such services are able to verify the authenticity of an email address by performing several tests, including checking the existence of the email domain and its mail exchange (MX) servers, checking for blacklists, determining whether the email is role-based or accept-all, identifying the type of email client used and more visit their website.

Some of the best email verification services offer a number of features that can improve your subscriber lists, such as deduplication, an API for real-time validation, and data enrichment, which identifies additional information such as full name and avatar. They also provide a variety of pricing options, including pay-as-you-go rates and volume-rate discounts.
