Right now, two of the most popular options are Airmail and Spark.

Lets take a look at what sets them apart.

The Contenders

Its impossible to sift through the countless email apps in the App Store.

How to Turn Airmail Into the Ultimate Email App for iPhone

For now, two of our favorites, Airmail and Spark seem safe.

This includes options like location-based notifications, customizable swipes, and more.

Spark(Free):Spark launched on iPhone first, butthe Mac app followed quickly thereafter.

Spark Is Great for Automated Email Sorting and Smart Notifications

Sparks main pitch is its intelligence.

It has a smart inbox, smart search, and smart notifications.

The smart inbox is the most important thing Spark does.

In my experience, this has always been pretty smart.

Its not perfect, but I generally dont miss anything too important.

Its helpful if you search through your email a lot.

Airmail has some of these features as well, but theyre not as much of a focus.

Airmail also has a smart notification feature, though it doesnt seem as robust or intelligent as Sparks system.

In short, Spark is about automation, while Airmail focuses on manual control.

Airmail has an absurd amount of customization options, from specific swipe actions for your inbox to location-specific notifications.

Personally, my favorite little change you’re able to make is the message preview size.

Everything else you expect to be here is here, like labels, filters, and different signatures.

Spark has a lot of customization options as well, but its not as much as Airmail.

Thats plenty for some people, so if customization isnt important to you, Spark should be fine.

In this space, Airmail blows Spark out of the water.

Spark doesnt come close to Airmail in this regard.

It integrates with the main cloud storage services alongside some big third-party options, likeOneNote,Evernote, andPocket.

Airmail is the clear winner here.

Being free, its easy to give it a test drive to see if it works for you.

It is customizable to an extreme degree and should suit anyone who relies on email for work.
