You can add email addresses one at a time or paste a list of items separated by a space or new line. To add a new email address, type it in the box and then hit the ‘Enter’ key on your keyboard or click the ‘Add’ button on screen to add it to the list items. If you paste a list of email addresses, they will be instantly added.

Email addresses are automatically alphabetized

Each stored list can contain up to 2000 email addresses.

Once you’ve reached the 2000 limit, you will see the counter highlighted and the ‘Add’ button will be disabled (grayed out). Click ‘Save list’ to continue.

If you send an MD5 hash of your email inputs, you should add MD5 hashes instead of plain text email addresses. Learn more about hashed email inputs.

Invalid email addresses are flagged at the top of the list. You'll need to remove all invalid email addresses before you can save the list.
