10 levels of email validation:

Syntax check

LetsExtract will exclude email addresses with an error, such as john,doe@gmail.com or gates$microsoft.com.

Check domain name and MX record availability

The program will check that the domain from the address exists and has a MX record in DNS. This is the fastest way to check if an email address exists.

Deep verification

This is the most reliable way to verify an email. LetsExtract will try to connect the domain and start the process of sending an email. We recommend installing the program on the server.

Checking for temporary addresses

The program will exclude addresses which are created with the help of disposable email services, such as 10minutemail, Tempmail, Mailnator, Guerrilla etc.

Check for free email addresses

If you are only interested in corporate addresses, you can enable this option and LetsExtract will filter out addresses located on such hosting sites as Mail.ru, Yandex.ru, Gmail.com etc.

Fake address check

LetsExtract is able to identify addresses, which are most often just a random set of symbols, for example 123@123.com, fksdfaas@mail.com, john.doe@gmail.com etc.

Uncensored words check

The built-in filter helps you prevent getting addresses that contain uncensored words to your mailing list..

Blacklists support

Because of blacklists, you can more accurately configure the program, as well as filter out addresses that are address markers for spam filters, such as abuse@, forspam@ etc.

Website availability check

LetsExtract will check if a valid site exists on the mail domain. For example, it will open the page https://gmail.com/ for yourmail@gmail.com

Filter by domain zone

Email Verifier has a filter where you can specify which emails on domains from which countries should be marked as valid or invalid.

LetsExtract Email Verifier checks email addresses quickly because of the multithreaded mode. You can save the result to a CSV or export it to Excel.

You do not need to use LetsExtract to collect email addresses. You can import your mailing lists into the program and verify them.
