I recently attempted to begin using the new updated Constant Contact. During this past year we did very little email marketing since our market had changed due to COVID. When I tried to make an updated news letter for about 600 customers, I found out during a test that it would not work with Microsoft Outlook. After contacting your on-line support and working with them for about 1/2 hour, they confirmed that the problem I was seeing was due to an incompatability of your platform with Microsoft Outlook. That is a platform that many of our customers use, so we are now looking for another email marketing supplier.
