Best Free Email Verification API In The World
1-Trumail
Trumail is a product or we can say service that was specially built with the intention of providing an easy to use API to software professionals who value a quality audience. Your apps registration workflow is one of the most important and complex parts of your software and it’s very important that you filter user credentials in a way that allows for future use. Invalid user credentials, particularly email addresses, should be deemed valid and deliverable at the time of signup.

Why Trumail.io
Now, take everything they have stated above, add some concurrency, multi-node load balancing, and some of the most efficient code they have ever written and you have one of the most powerful and resilient email verification platforms available today. They are always looking deeper and finding new ways to optimize our service in order to give you and your users a more streamlined and secure experience and they hope that you appreciate and take advantage of what they have built!
The one big thing that makes Truemail.io service unique is that the prices are displayed clearly and openly on its website for their visitor. I think Trumail.io deserves the praise for doing this.
2-Mailboxlayer
Mailboxlayer offers a simple REST-based JSON API enabling you to thouroughly check and verify email addresses as they come into your system.
In addition to checking the syntax, the actual existence of an email address using MX-Records and the Simple Mail Transfer Protocol (SMTP), and detecting whether or not the requested mailbox is configured to catch all incoming mail traffic, the mailboxlayer API is linked to a number of regularly updated databases containing all available email providers, which simplifies the separation of disposable (e.g. “mailinator”) and free email addresses (e.g. “gmail”, “yahoo”) from individual domains.
3- Debounce:
DeBounce is an email validation solution that dramatically improves email delivery rate and sending score. The software scours the users’ email contact lists, weeding out inactive emails, duplicate emails, invalid emails, spammy and non-functional mailboxes, leaving them with a clean list of email addresses that are operational and regularly used by their owners.
With DeBounce, users never have to worry about emails, newsletters, promotional messages, and information blasts getting bounced, sent to the spam folder, and not reaching their intended recipients.

If you would like take my recommendation out of this above list I will go with Trumail.io.
