The new Recap feature will appear every morning in the app. Along with conversations that need a reply, it covers mails with due dates and reminders.
It will show a blue dot whenever something requires your attention. Users can either swipe to dismiss the emails or come back to them later.
You can select to also receive a notification if there are Recap emails. Showing only the most recent conversations on a given day, they will disappear after a few days or when you deal with them.
Past the new feature, the app itself is definitely one of the best third-party options on the App Store. Some of the headlining features include read receipts, snooze, send later, undo send, sender profile, and connected apps.
Newton Mail is designed for the iPhone and all iPad models. It can be downloaded now on the App Store for free.
