Check the validity of one or a list of email addresses to find out if they exist and are valid

Check email If we have to send an email and it comes back due to an error, it may be that the email address is wrong. Before sending an email to an address that we had never used before, it might be useful to check that the email is valid and accurate, even more so if we have to send a message to several different emails.
Fortunately, in all these cases there are online tools which can be used effectively for check if an Email address exists and is valid, that is, that it is really reachable.

In this guide then we will show you how to find out the authenticity of an email address starting from a simple e-mail address, using one of the many online services that, always respecting privacy, allow you to know in advance if the e-mail is valid.

How to find out if an email address exists and is valid

To do this type of check we will have to retrieve the email address and enter it in one of the sites seen below, so that we can immediately get an answer on the authenticity of the address and be sure to be able to send the message immediately, without run the risk of it coming back.

The first site that we recommend you use is Email Verification, offered by one of the most famous sites for verifying the IP address of the connection.
My IP mail
Using this site is really very simple: we enter the email address in the field Email to check, we press the button Verify and we check what information can be retrieved about it. If the email exists, the message will appear The email exists and is functional, otherwise we will see the writing appear The email does not exist.

Another similar service that we can use is offered by, among the best in the category.
Email toolset
Also in this case we can check if the email really exists by entering the address in the field Write email address to verify, clicking on the CAPTCHA control at the bottom, passing any secondary checks and finally pressing on Verify Email. After pressing the button we will immediately receive a clear answer of the type Email address exists! and, by scrolling the page, we will also get the response of the mail server used for the test, so as to be sure that the email really exists and is being used.

If we often use a lot of unknown emails, we can rely on the service offered by the website
Verify email
As already seen for the previous sites, all we have to do is enter the address in the appropriate field and wait for the results of the check (very accurate), complete with information on the answers obtained from the server, on the type of authentication and on the protocol used for the exchange of emails.

If we have a lot of emails to check, we can get help from the EmailListVerify service, a really valuable ally for advertising companies or for those who manage a newsletter or a mailing list.
After creating a free account, it will allow you to upload the list of emails in various formats (CSV, XLS, TXT), so you can immediately check a large amount of emails and find out which ones are up and running and which are not. The free version offers up to 100 email checks; if we have larger lists we will have to subscribe to one of the proposed subscriptions.

Another good site for checking valid and existing Email addresses is
We now know the procedure very well: we enter the email address to be checked in the field Enter an email to verify, we press the button To verify to immediately receive the result of the check. This service also offers the possibility of checking a maximum number of emails (per newsletter), paying a sum based on the number of emails to be checked (starting from € 7 per thousand emails, but just post the cursor on the prices page to get the tariff).

If we have a lot of emails from overseas users, it may be a good idea to use a foreign service like
As already seen on other similar sites we will be able to check the emails by entering the address in the appropriate text field, passing the CAPTCHA test and finally pressing the button Verify Email Now, so as to quickly find out if the email is really active and has been used recently. Although the site is in English it is very simple to use, there shouldn't be any particular problems.

Another foreign site similar to the previous one and useful for finding out if the email address exists is
Once opened, enter the email address to be checked in the central text field, press on Verify Email and we discover all the data on the address entered, in particular if it is really active and if it is used recently. This service also offers a massive email control platform at very competitive prices.


All the services that we have reported above are really great for doing a quick check on a single email address but, as we have seen, most of them also offer a control system for massive emails, really very useful if we manage the marketing of a company or we provide a newsletter for our site or blog, so that we can immediately remove fake emails, duplicate emails, non-existent emails or those that have been deactivated for inactivity.
