Each lane contains a list of emails that you need to act on. - For the Action lane, you can quickly reply, dock an email on a specific date or send a meeting invitation. - For the Review lane, you can swipe to archive or discard the email. - For the Cleanup lane, you can leverage our powerful bulk Cleanup functionality to clear hundreds of emails in seconds. ⎯ DROPS: INTELLIGENCE WITHOUT THE COMMITMENT Every new account gets 30 free Drops. Enough for about 12 to 14 days of active use. Drops never expire and are only consumed when you use them. Skip a day, skip a week. You don't pay for days you're not working. Once your free Drops are used, Ocean's core features remain free forever. Need more? Drop packs are available for quick top-ups. Or go Ocean Blue for 50 Drops every day, refreshing at midnight.
