HIS mailing lists offer reliable, high speed delivery to subscriber lists of all sizes.  Lists may be two-way, where subscribers can post to the list, or one way, where only the list administrator can post.  One-way/broadcast  lists are ideal for delivery of newsletters and product announcements.

List configuration is very flexible - lists may be open (anybody can subscribe themselves) or closed (you have to approve subscription requests). You can choose between moderated (you approve all messages sent to the list) or unmoderated (messages are posted to the list automatically).  You can even choose to have some members moderated and others unmoderated.

Subscribers can elect to get their messages in digest format - this is popular for discussion lists where there are many individual posts each day. Some subscribers prefer to get the day's messages bundled together in a single "digest" rather than as individual messages.

The web-accessible archive is a popular way to offer your subscribers (and non-subscribers) a way to view your list messages by date, author or subject. Your archive can be public or private.  The archive can be browsed by date, subject, thread or author, and is fully searchable.  The archive is updated automatically as new messages are posted, so it's always up to date.

Another important feature: automatic bounce management.  Subscribers are constantly changing their addresses and cancelling their old accounts, and Mailman frees the list Administrator of the task of managing email bounces from old/erroneous email addresses by automatically unsubscribing members whose mail starts bouncing consistently.

Mail coming in to our list servers is filtered for spam, viruses and phishing messages.  Normally lists are set so that only subscribers can post messages, so the risk of spam being sent to the list is small, but the pre-filtering that we apply reduces the risk even further.

Our list servers are tuned to deliver their mail at high speeds - as the list messages are generated, they're immediately handed off to servers whose only job is to deliver the mail as quickly as possible.  Most messages are delivered within seconds of the time they're generated; it isn't always possible to deliver 100% of the mail immediately, since the receiving mail server might be down, but our servers keep trying until the delivery succeeds.

When we set up your list, we set reasonable default values that  you probably won't need to change, but if you do want to make changes, you can do so at any time via your list administrator's control panel.
