How to import subscribers from a CSV file

Learn how to import subscribers to Letterhead using a CSV file

Letterhead's ESP, which includes subscriber management, is currently in an alpha testing stage, meaning it is not fully stable and only available to a few users.

The Subscribers page is where you can view, add, manage, and import your newsletter subscribers.

To access the Subscribers page, click on Subscribers in the Letterhead menu.

    1. Click the Upload CSV link under the Add subscriber button.
    2. Upload a CSV file of your subscribers. Your file must match the format of our template, for example:

      1. The name of all four properties, using this exact spelling: name, email, status, and tags, must be included in your template.
      2. The subscriber's name, email, and status are required fields; tags can be empty.
      1. You must enter either 0, 1, or 2 in the status column. The numbers represent 0 Not subscribed, 1 Subscribed, and 2 Unsubscribed.
      2. The tags must be separated by pipes ( | ), and you can enter new and existing tags.
    1. If the import is successful, you will get a success message and a confirmation email after the upload.
    2. On the Subscribers page, use the search bar to find the contacts you have imported from your .csv file — make sure to refresh the page if you don't see your contacts right away.
