Esumsoft

Esumsoft develops Windows desktop software, including POP Peeper, a freemium email notifier, and Aeris Calendar, a desktop calendar. POP Peeper lets users monitor multiple email accounts in one place, supporting POP3, IMAP, SMTP, SSL/TLS, OAuth2, RSS and other protocols. It provides email viewing, deletion, printing and sending, along with portable operation, password protection and privacy and security settings. Account setup is handled by entering an email address and password, and the program offers a range of notification options.

POP Peeper includes message searching, AntiJunk/AntiSpam, rules and a spell checker in its Pro edition, with plugins, notifier options, skins and language support also available. Aeris Calendar combines a desktop calendar with current weather conditions, forecasts and severe weather alerts, and supports reminders, notes, events, birthdays and holidays. Both products are available for download, with paid editions and a bundle option offered for POP Peeper; the pages do not state whether the paid options are subscription-based, seat-based or usage-based.
