In this article, I have compiled a list of 6 free bulk email verifier websites. These bulk email verifier websites perform deep checking to verify an email address. They perform RFC syntax check and use SMTP and DNS techniques to ensure deliverability of an email address. You can use these websites to bulk verify emails and export the verification results. Some of them even allow you to export a list of valid and invalid emails separately. These websites allow you to specify email addresses either by uploading a TXT, CSV, etc file or directly copy/paste into their text area and after a press of a button they verify each email and display results.

Bounceless:

Bounceless is another free bulk email verifier website. In its free plan, you can verify 100 emails per day for free. Like other bulk email verifier services included in my list, it uses SMTP along with DNS lookup and MX loop to check for the deliverability of an email address. Before moving on to bulk verify emails using this free website, you need to create a free account on it. After you have created a free account, log on to this free web service and you’ll see its interface as shown in the screenshot below.Bounceless- free bulk email verifier website

NeverBounce:

NeverBounce is another good email verification website. It performs an advanced level of email validation, and has a 12 step process to validate emails. This includes DNS & MX Validation, Domain Health Check, Syntactic Validation, Social Validation, check for disposable emails, and more.

Now, what I really like in this service is that it provides API for email verification. If you create a free account, you can do 1,000 email checks free every month using free API calls. You can also check 1,000 single emails per month for free from its dashboard. If you go with paid account, you can go with bulk email verification via API. The API also lends itself to real-time validation, so you can integrate it with your existing products.

I tested the API, and it worked very well. There is a detailed documentation of the API here. You will need API key etc. to call the API, which you can get from your dashboard once you create a free account.

Neverbounce API Call

I tested the API with a valid email address and an invalid email address, and it gave correct results in both the cases. Then I tried API with a spam trap email address. To my surprise, NeverBounce did not classify that email address as a valid email address, but actually classified that as Unknown. Spam Traps are very hard to identify, and the fact that NeverBounce did not classify that email as valid shows high quality of email verification logic that NeverBounce uses.

This service provides some other features also for free, like, free list deduplication, free list analysis to show quality of list, etc.

Hunter:

Hunter is another free bulk email verifier website. In its free plan, you are limited to 150 free email verifications per month. It validates email syntax, checks for MX records of an email address, checks for the presence of an SMTP server, and performs SMTP checks to validate email addresses. To bulk verify emails, you first need to create a free account on it from here. After that, log in to your account and switch to Bulk tab. Now, click on Access button next to Email Verification section. It will then take you to its bulk email verification page. Click on + New bulk button and upload a TXT or CSV file containing email addresses. Then, click on Verify button. It will perform all the checks mentioned above to bulk validate emails. After validating all of the emails in the list, it gives you the option to download the result file as a CSV file. It also lets you choose which list of emails you want to download i.e deliverable emails, deliverable and risky emails, or all emails.

Verdict:

In this article, I have introduced you to 6 free bulk email verifier websites. All of the websites included in this article perform deep checking by using SMTP and DNS techniques to verify an email address. However, there are some limitations on a number of emails that you can verify in bulk using their free version. I can recommend QuickEmailVerification and Bounceless as they allow you to verify 100 emails per day and Email Verifier that allows you to verify 20 emails per execution and there is no limit on a number of times you can execute it. And if you want to go with API based verification, then NeverBounce is pretty good as it gives 1,000 free single API calls free per month.
