Mail blindingly fast. ListManager can scale to send 500,000 unique messages and more per hour. Front-end server clustering lets you balance the load of processor-intensive functions among several servers for faster, more redundant performance.

Send anything you want. ListManager can send HTML/AOL/MIME messages, attachments, and international (double-byte) characters.

Password-protected interface. All security levels (list, site, and server) are individually password protected. You can also restrict access to a limited range of IP addresses.

Configurable logging. Maintain complete or selective logs of different kinds of server activity, to assist in security, archiving, and diagnostics.

Custom template wizard. Create and save your own fill-in-the-blank templates, allowing users without any HTML knowledge to create attractive messages in your standard format.

Content converters and validators. Convert your email content to and from text, HTML, and AOL formats. Quickly detect broken links and remove code that could cause problems for AOL, Hotmail, or Yahoo! users.

Mail merge. Merge text into your email from ListManager's built-in database table, or fetch data from a web server.

Message sending statistics. See message deliveries, retries, and soft vs. hard bounces as your mail is being sent.

Individual member reports. Review current detailed information about any list member at a glance. One click gives you both demographic data (including member name, status, member ID, join date, etc.), as well as mailing history (such as recent opens).

Add list members easily. Add members via your Web site or use our convenient member import wizards.

Convenient web forms. Create and access all the forms you'll need to manage your mailing lists. Now it's even easier for your list members to subscribe, unsubscribe, and refer new members.

Hassle-free scheduling. Schedule your messages in advance for one-time or repeat distribution.

Approval wizard. Approve or reject messages in bulk, rapidly moderate, or reject messages with specific feedback to the contributor.

Failsafe unsubscribe. Include one-click unsubscribe links in the footer of your messages. Members can unsubscribe by web or email.

Customizable confirmation, hello and goodbye documents. Send custom confirmation and welcome messages when members subscribe or unsubscribe.

Convenient member profile forms. Let your list members update their preferences or other demographic information with easy-to-use web forms.

Discussion forum/archive interface. Our message reading interface makes it easier for your list members to participate in group discussions, view archived messages (text, HTML versions, and attachments), and manage their list memberships.

Spam protection. By requiring new members to have their first message approved, you can keep spammers off your list.
