I have constructed lists for 100,000+ emails with a certain logic. Your changes have eliminated me being able to function! In particular your changes to the search and eliminating the "Advanced Search" is a disaster! Please Please revert or give us the option of keeping the old platform. so I can run my business efficiently. Otherwise it is time for me to find a new email provider as the ability to search/sort/reassign large data sets with multiple search criteria is completely gone. Very unhappy camper.
