Kimpa is email, calendar and files for your Kimpa business account, in one app. Mail Your inbox sorts itself into Primary, Social, Promotions, Updates and Forums, and Smart view pulls out what's important and what's waiting for your reply. Snooze a message, schedule a send, star, archive and search across every mailbox you add. Replies and forwards keep the original message's formatting, and emails look the way their senders designed them, in light and dark mode. Warnings when something looks wrong When a message may be impersonating a person or company you deal with, Kimpa shows a warning above it, so you can check before you reply or pay. Calendar, Contacts, Tasks, Notes and Reminders Plan meetings and events, keep your contacts in one place, track tasks, write notes and set reminders. They all use the same Kimpa account as your mail. Kimpa Drive Store your files, move them between folders, share them, search all of Drive and restore from trash. Kimpa Docs, Sheet and Present Open documents, spreadsheets and presentations from Drive or from mail and edit them in the app. Kimpa Team The Team tab opens Kimpa Team, where your workspace has its channels, direct messages, calls and meetings.
