En gmail, the approach changes radically with its system of smart labels and filtersEach email can have multiple labels and be categorized into different tabs (Primary, Social, Promotions, etc.), which improves automatic classification and visibility. Gmail's advanced search feature, powered by Google technology, is a key ally for finding any email in seconds, thanks to its multiple search operators.
