If you are a heavy email user and these features entice you, give the free trial a run to see if it's worth your money. If you want your computer email experience to look and feel more like a mobile experience, with big, easy-to-find action buttons, Polymail is the one for you. • Free with a monthly subscription - Spark. Spark has this 'Smart Inbox' feature that separates out what is Personal, Notifications, Newsletters, Pinned, and Seen. That is, any email that is from someone in your contacts or otherwise looks like a personal email will be filtered to the top of the inbox list. Below that, in a separate section, emails that look like alerts from companies you deal with, like your gas company or Amazon, that include some kind of alert or notification. Below that, you'll see a section called 'Newsletters' which is exactly that.

That means if I have Airmail or any other third party mail app running, that app will still push and fetch mail like normal. Unless I manually disable those features inside that particular app, I’m not reaping all the benefits of Low Power Mode. To find out how much validity there was to my theory, I used Low Power Mode for several days. Some of those days I used Spark or Airmail and some of those days I completely uninstalled any third party mail app and strictly used Mail.app. The days I was only using Mail.app, I typically ended the days with 15-25% more battery life. Sure, some of that could be contributed to different usage patterns. I’m not claiming my tests were scientific by any means.

Spark even lets you dial down notifications to just the emails it thinks are important, kind of like how Mail separates VIPs from the rest of pack, only you don’t have to manually flag the worthy contacts. If you miss Mailbox's scheduling and snoozing, Spark will get you back on the path to Inbox Zero. But Spark’s smarts don’t stop there. The app connects to all of the major cloud services (Dropbox, iCloud Drive, OneDrive, Evernote, etc.), so you can attach and save files with ease, while slick Pocket compatibility lets you save links for later reading. A Fantastical-like natural search engine even amplifies your searches, helping you find messages and attachments more accurately, and you can save frequent searches.
