There are two options for importing contacts, and both sound similar at first:
- Import your email contacts: List them all in a file, upload to Facebook, and they’ll receive suggestions of your page.
- Provide Facebook with your username and password for any email software or site that you use, and then everyone in the address book will see your page suggestion.
You can access the contact importer within the page manager tool. Click on the marketing tab, and then check out the part labeled “tell your fans.”
Like you see in the screen shot below, files for uploading need to be in Outlook, Constant Contact or .CSV. Notice how Facebook has a placeholder for the addition of more file formats, conveniently called “etc.” for now. However you choose to upload, you’ll see a progress bar until the job completes.
