Our June edition Vertster Optimizer is launched this morning and is now online here. This month, we are testing out a different email service provider named Vertical Response out of San Francisco.

I have always questioned the deliverability of our other provider StreamSend. So this is a test, and we’ll find out which works better or if it is a wash. Streamsend has prettier graphs, and their interface is quite a bit different from Vertical Response’s. Our list is squeaky clean double opt in, but I have seen lots of people subscribe several times in a row on Streamsend, apparently unable to get the confirmation email.

I will let you know my results in a few days.
