How To Use Email Verifier

Email Verifier is designed to reduce the labor and cost of verifying if emails on your email list can receive your messages (and those from other senders). So, the setup and use is straightforward.

After downloading the app, you will be taken directly to the tool's user interface.

Note: The tool makes it easy to upgrade your subscription. Just click this page's “Upgrade” button to begin the process.

The user interface has two boxes for uploading a file or entering email addresses line by line. There is a green “Verify” button at the bottom of the page.

You have two options: to the left, drop in a .CSV file or XLSX file that contains your email address list, or add individual email addresses (one per line) to the right.

You can drag and drop your file to the box on the left. Once you do, you’ll be given a preview of the table before you run the report.

Once you drag your XLSX file or CSV, the interface generates a table preview to show how your email addresses will be checked.

There are some limitations to the size and type of files uploaded:

Maximum file size in 5 MB
XLSX—not .xls files
If there are multiple tabs, the tool will read just the first tab

On the right, you can enter your email addresses individually, line by line.

The app has users enter individual email addresses on the right, one per line.

Once you’ve input your list, click the “Verify” button.

A red arrow points to the green Verify button at the bottom of the screen.

A new pop-up will appear as the app examines your addresses. The app gives you a time estimate to completion on the right.

A pop-up window will give you information about your impending report as the tool combs through your email addresses.

Once the app is finished, the pop-up will say “Verification result” at the top. The total emails, emails left, and time left estimates will disappear.

You will then have two buttons to choose from: “Go to reports history,” which will give you a deeper breakdown of the results, or “Go to main page” to return to the home page.

The Verification result window has two buttons to choose from, “Go to reports history,” which will give you a deeper breakdown of the results, or “Go to main page” to return to the home page.

If you click “Go to reports history,” you will see a page like this:

The Reports history page determines each individual email’s status, and users can see the number of “Verified emails” and “Others” at the top of the page.

This Reports history page shows the total number of verified emails at the top, and it breaks down issues the app found with other individual emails.

You can also manipulate the visual bar graph by checking or unchecking the different results boxes.

The colorful bar graph in the Report history section can be manipulated to show only the type of email you are looking for. For example, unchecking every box except Catch-all will give you a visual representation of the email addresses that fall into that category.

Once you’re ready, click the gray download button at the top of the page.

The download feature is at the top right side of the page. It is a gray button that says Download.

You will be asked if you want the downloaded file delivered as an XLSX or a CSV. Once you select the preferred file type, you’ll get a download that looks like this:

The example CSV file has a gray-and-white table full of email addresses. To the right, each email address’s status is shown.

This download will help you determine which email addresses to drop from your mailing list.

For example, say you planned an expensive email marketing campaign around the holidays. You might want to reach out only to “Verified” email addresses to lower the cost of the campaign and boost the ROI.

But maybe business is slow in the spring, and you want to cast as wide a net with your emailing campaigns as possible to bring in more customers. In this case, you might want to keep “Verified,” “Catch-all,” and “Unknown” email addresses to have a better chance of reaching more people.

We’ll talk about what the statuses mean next.

How Does Email Verifier Work?

For each email, the app:

Checks the format (to verify the address itself is spelled correctly)
Verifies DNS records of the email's domain (checking for MX records)
Connects to the MX server listed in the DNS records
Initiates an SMTP session with the listed MX server to check if it would accept mail for a given email

Note: The app does not send an email to the addresses you enter. The app terminates its connection to the MX server once it confirms (or rejects) the readiness to accept email for a given recipient.
