Adding List Members (Subscribers) Guide

Creating a .CSV File of Your Subscribers

There are many different ways to add your subscribers to your list. One method is described below. Probably the easiest way to add your subscribers is to simply log in to your control panel and paste in your subscribers under Add Many Members.

If you have many subscribers to add to your list or you also desire to include various demographic information with field values such as Client, Prospect, ZipCode, State, AreaCode, ItemBought, AmountPurchased, Paid, FreeTrial, ExpireDate, Gender, MaritalStatus, Birthday, etc. the best way to do this is by creating and importing the data from a .CSV file (comma separated value). One reason to do this is so that you can subsequently query on this information to create different segments that you can send mail to. Another reason is so that you can perform a mail merge with this information in order to automatically insert these values into your email messages.

  1. Create a .csv file
    Note:To create a .csv file it is best to use Microsoft Excel or a similar program. When saving an Excel file, your file must be saved as a .csv. To do this click File and Save As. Choose CSV (comma delimited) *csv. from the Save As Type drop down menu located at the bottom of the window, then click Save
  2. In row 1 enter the custom fields you would like to use, see How to Create a Segment for a list of available fields
