How ?

Simply hide the Delivery Console display during the sending process (click the Hide button). There is a lot of detailed progress information being displayed here and this takes valuable processing time away from the actual delivery process.

In our test, sending to a group of 25,300 recipients using 1 connection to the mail server, reconnecting every 50 messages for 5 seconds, hiding the delivery console increased the send rate from 9,270 messages per hour to 13,875 per hour. That is a time saving of almost an hour over the course of the mailing, reducing the overall time from less than 3 hours to less than 2 hours for the full mailing.

When the Delivery console is hidden to view the progress of the mailing, simply right-click on its icon in the task bar and choose “Delivery Console Status” to make it visible again.

Also if using the Subscriber Add-on to process inbound messages (bounces, opt-in and opt-out requests etc.), minimise the Subscriber Add-On window and hide the “Subscriber Progress” screens to get similar performance gains.
