EMAIL VERIFIER

Verify the deliverability of any email address.

This email verification tool actually connects to the mail server and checks whether the mailbox exists or not. Email Checker is a simple tool for verifying an email address. It's free and quite easy to use. Just enter the email address and hit the verify button. Then it tells you whether the email address is real or not. It extracts the MX records from the email address and connects to the mail server (over SMTP and also simulates sending a message) to make sure the mailbox really exists for that user/address. As it uses our unique set of data, the Email Verifier can return a result even where other standard verification tools fail. Our validation process has multiple treads: email format, domain information, server status, and email type. We constantly strive to enhance our email verifier techniques, and improving our services for you is our top priority in order to offer you an optimal experience to verify an email address online. We have helped countless numbers of email list brokers, email marketers, data centers, call centers, and lead generation groups by checking the email addresses. Let us help check your email lists and reduce your bounce rate during your next marketing campaign.

Common questions about the Email Verifier

Who is it for?

Everyone who sends email in whatever volume (from 1 to millions). Sending an email to an address that doesn't exist results in a "hard bounce". Our email checker helps you by removing the invalid email address from your mailing list and increasing future email deliverability.

By implementing our email verification technology, you can remove bad or invalid email addresses from email campaigns before hitting the "send" button. Because bad email addresses have been removed before sending, the amount of hard bounces is dramatically reduced thereby saving time, effort and expense associated with processing invalid email addresses.

What is the use of the Email Verifier for online businesses?

As an online business, you want to attract new customers. You want to identify and nurture your best customers and build meaningful business relationships. Unfortunately, not all customers that arrive through your public-facing on-boarding process wish to engage with your business in a meaningful way. Some typical use cases and traits of new clients that are of a lower quality are:

  • Free trial abuse - Does your business offer limited-time free trials of your product or service? If so, you might have noticed new leads signing up for multiple accounts rather than engage with your paid options.
  • Free content - If your business offers digital content (e.g. e-books) in exchange for an email address, your customer may provide a temporary, one-time burner (or disposable) email address.
  • Fraud - If your business accepts payments online, it is liable to settle charge-backs due to fraudulent transactions. When a customer is engaged in using stolen payment details to buy from your business, the customer is unlikely to provide an email address that can be traced or held accountable.
  • “Bad data” in your CRM - Bad (undeliverable) or junk (disposable/temporary/burner) email addresses in your back end systems need managing, pruning and updating at some point. This maintenance activity takes resources away from what your business would rather be doing to grow.

If your company is having trouble signing up with burner/temporary/disposable email addresses, you will be pleased to hear that our systems provide some of the most robust identification of disposable email providers available anywhere. Unlike other providers who use simple static lists of burner email providers, our systems go further and use sophisticated machine learning algorithms to track more elusive disposable address providers.

Can a "valid" email address bounce?

The verifications are never totally sure, but we can guarantee that more than 95% of "valid" email addresses won't bounce.

What does it mean when an email address is marked "catch-all"?

When you perform an Email Verification, the result might be "catch-all". Some email servers accept all the email addresses on the same domain name, whether they have actually been created or not. In this case, we can not make sure that the email address tested actually exists or just return the "catch-all" status.

Does it send an email to do the verification?

The email checker does the validation without sending an email, by directly connecting to the SMTP server.

How much does it cost to use the Email Verifier?

It's absolutely free. In the near future, we are planning to launch our premium features.

What do you check for when verifying emails?

This is the list of the verifications we perform:

  • Email Format: First, we verify the format of the email address is correct and looks like "name@company.com".
  • Disposable Email Address: We check if the email address has a domain name used for temporary email addresses.
  • Webmail Email Addresses: We verify if the email address uses a webmail like Gmail or Yahoo.
  • Presence of MX Records: We check if there are MX records on the domain. If there aren't, the email address can't receive emails.
  • Presence of SMTP Server: We check if we are able to connect to the SMTP server (indicated in MX records).
  • SMTP Check: We test the email address and see if it bounces or not, without sending an email.
  • Accept-all Domain: We check if the server has a catch-all policy that accepts all the email addresses.
