clients still make sense for users with multiple accounts. and modern clients only sync a subset of the db but still permit online search and retrieval. also for certain tasks the web clients aren't much better (gmails interface is garbage for working with multiple messages for example) the default answer to op's question in enterprise land (where windows is still treading for relevancy) is Outlook. thunderbird suffers the issues the comment mentions above -- barfs with large dbs, no support for exchange, not sure if it even supports push notifications, etc it should be noted that mail on mac works well and the win 10 mail app this article is all about works pretty well too, which is why its a travesty MS is going to ruin it.
