Customer Announcements: Whether it's a sale, a product release, or a reminder that tax time is coming, customers respond to targeted, timely messages. Are you reaching out to them, or are your competitors?
Work Group Forums: Group forums are a great option to keep individual projects or groups on track. Give your accounts receivable its own list, or start a new list when your company gets a new project, and your individual teams can discuss their work via email, with a private, password-protected archive they can always refer to.
Company Lists: When your company has social or work events, a company-wide one-way list can make life simpler. Multiple moderators can be assigned to post or approve emails. This makes important information about policies or events easy to send to everyone, and prevents inadvertent replies from being seen by every employee.
