Mustang List provides you with the functionality to import subscribers from a csv (Comma Separated Values) file.

1. Click List Administration, then Import Subscribers. Click the Browse button and locate the csv file on your computer. Once you've located the file, then click the Upload File for Import button.

2. The file you selected will be uploaded to Mustang List, and the system will read through it in preparation for step 2. We show you information from the first record in the file so that you can tell us which columns contain which information. The only required field is email address, all others are optional. To identify the information, just select the proper entry from the drop-down on the right. If you do not want to import a field, just select "Do Not Import This Field".

3. There is a global option that may save you time and effort. Usually, addresses in the same spreadsheet have something in common, like a category. If you have established categories for your list, you can assign a category to all addresses you are about to import. This saves you the time of assigning categories after the addresses have been imported. If you select a global category for this import, you cannot also identify a field as a category - the two are mutually exclusive.

4. When you've identified the fields you want to import, we're ready to validate the addresses in your csv file. Just click the Begin Address File Validation button. In the validation process we are checking to be sure the address is properly formatted, that it is not already in your list, and that it is not on the banned list. So that you don't waste time waiting, we'll send you an email message when we've finished. The message will summarize the results, and show you the addresses that were not imported so that you can decide how to handle them.

5. The next step is to decide if you want to continue with this import process or to abandon it and start fresh. Perhaps you incorrectly identified a field or you want to correct addresses that had errors. To abandon this import, just click the abandon link in the email message you received. Otherwise, to finish the import process, click the finish link. If you chose to finish the import process, you need not wait. We'll send you an email when the addresses have been imported and are ready for you to use.

6. That's it - the import process is complete.
