Can I create a new list in Salesforce.com from an external file?

It is possible to import an external mailing list, in either a .txt or .csv format, however you cannot use the Update Statistics feature since the list data lacks any association to existing Salesforce.com Leads or Contacts. Mailing lists created from Leads & Contacts, or a Salesforce.com Campaign, include a Salesforce.com record ID. This data is missing from any list created from an external file.

To create a list from an external file, follow these steps:

1. Login to your Salesforce.com account
2. Click New List
3. Select the Import an External Mailing List option
4. Follow the steps to complete the import
