Any issues with open and click rates for Adobe Campaign Classic v7 Release 7.2.2 - build 9349?
We have notice a sudden drop in Open and Click rates on Transactional Messaging. This drop started in September 2022 and taken 50% drop. We have not changed any templates other than a subject line on one campaign, and we had to change the Web Analytics Connector for the new external account. We are on Release 7.2.2 - build 9349 for Adobe Campaign Classic. Thanks in advance and let me know if you have experienced such drastic decreases. Appreciate your help if you can provide which area to look into and the fixes.
