Compare account limits and app coverage with offline access, unified inbox, calendar tools, and scheduled sending. Free plans and “Paid from” pricing provide further cost context. The ranking opens with Mozilla Thunderbird, Hiver, and Front, followed by Newton Mail and eM Client. Weigh those listed features against how you organize messages and the devices you use, including whether offline access, calendar functions, or a consolidated inbox matter to your routine.
