Bulk Email Verifier

Verify a list of email addresses.

Uploading a File

Our system is designed to handle CSV and TXT for all delimiters. However, if you do run into any errors, there are a few things you can do to make the process more smooth:

  • If you are using a spreadsheet or CSV, make sure that all of your emails are in the same column.

  • Before uploading a CSV, it is always a good idea to open your list in a spreadsheet editor (Microsoft Excel, OpenOffice Calc or Google Sheets) and save as a CSV. These programs ensure that your CSV is properly formatted.

To get started with the Bulk Email Verifier:

  • Go to the Bulk section of your account.
  • Click on Email Verifier.
  • Select + New bulk.
  • Pick a name for your list so you can find it easily later on.

Here are the possible verification statuses:

  • Valid: the email can safely be used.
  • Accept all: the email server has the policy to accept all email addresses, which prevents us from finding out if a mailbox is set up for this address. There is a chance that the email could bounce.
  • Invalid: the email cannot be used as it would bounce back.
  • Unknown: something is preventing us from knowing the verification status, such as a block or a time-out on the email server side. There is a chance that the email could bounce.
  • Webmail: the email is a webmail (gmail.com, yahoo.com, etc.) and has not been verified.
  • Disposable: the email is temporary and should not be used. It has not been verified.
