How to verify an email list

All plan upgrades will receive a limited number of free email verification credits. These credits can be used to verify a list of email addresses by clicking on Email verification in the left-hand menu.

Verify a new list

To verify a new list, click the Verify new list button and upload a CSV file. Excel files are not supported and will need to be converted to CSV. If the file has more than one column, you’ll be asked to choose which column of emails you want to verify. 

Once the file is imported, you’ll be shown the number of credits the list verification will require. If you have sufficient credits, you can click on Verify list. If not, you can purchase additional credits on the Plan & Billing page.

After selecting Verify list, the verification will happen in the background, so you’re free to navigate to other pages or grab a coffee.

Reviewing the email verification results

Verifying your emails is just the first part of cleaning your email list. The real value comes when you understand how your emails are categorized and adjust your email lists according to our recommendations.

To see the details of your verified list, click on Manage next to the relevant list on the Email verification page.

In the email list verification results, you can see all verified emails and their statuses. The pie chart visualizes the email statuses found in your list during the verification process. The number in the center is the total number of emails that were verified on your list.

The right side of the page displays individual statuses, along with the number of emails that each status has been assigned to.  

To download a CSV file detailing the results for a specific status or to download all results, simply select the attributes you want to include, or click Select all, and click the Download Selected button.

Adding invalid emails to your suppressions

You can add invalid email addresses directly to your suppressions list in MailerSend. To do this:

1. Click the Emails tab on the results page.

2. Filter the emails by status.

3. Select all and click the Add to blocklist button.

What do the statuses mean?

Send to	Valid	Email is safe to send.
Risky	Catch-all	Recipient's mail server will accept emails to this address but we cannot guarantee this email address belongs to a person.
	Mailbox full	Recipient’s inbox is full and may not be able to receive new emails.
	Role-based	Email is role-based and may not be associated with a single, specific person but a group of people.
