Simultaneous Sends

The number of messages ListManager will attempt to send concurrently. At any one time, ListManager can send up to the number specified here. The number of simultaneous sends is limited by your license. Contact your account representative at 800-768-2929 or at sales@lyris.com for more information about increasing your mailing speeds.

Normally, ListManager sends mail out as quickly as it can. However, because it is so efficient at sending mail, ListManager can fill up the capacity of your Internet connection, so that other people using your Internet connection have are slowed down.

If you would like to have ListManager use less Internet bandwidth, you can slow down the pace at which it delivers mail. This is accomplished by limiting the number of simultaneous mail sessions.

The number of threads that you can launch is limited by available memory. If you exceed the number of threads that your system can handle, your ListManager will behave incorrectly, because your system will run out of memory. Generally, a setting of 150 or 200 is quite safe on a machine with 128mb of RAM.
