Hello. Beginning in the middle of December, the open rates on our newsletters composed on Blox and sent through Constant Contact have plunged from about 50% to the low single digits. This is only happening with the newsletters we create in Blox. The newsletters that we create and send directly from Constant Contact still have those high open rates. I've contacted Blox support and Constant Contact support but so far the problem continues. Has anyone else using Blox and Constant Contact faced this same issue?
