Spark makes it easy to go through your inbox faster than ever before. No matter if it's one new message or hundreds, you can do it in a couple of minutes. Moreover, Spark is powerful, smart and fully customizable!

Smart Inbox automatically detects if an email is personal, a notification or a newsletter and groups it with similar emails for easy batch processing using beloved swipes. With just a glance, you can see if emails are important or just a product announcement from a service you've never used.

We all love the feeling of accomplishment when we have finally dealt with our inbox. Spark makes this easy to achieve. Quickly process your emails, swiping to archive or delete as necessary. Pin emails which relate to things you need to do today, or quickly swipe left to archive those you've already dealt with. If you can't finish a task today, swipe to snooze for tomorrow or another day (if you're really busy).

Quick replies let you reply to a message with just a tap. Like an email, say thanks, or send your own “Quick Reply” by tapping the relevant button at the bottom of any email. This is especially handy on Apple Watch, where you can quickly reply to an email on your wrist. Need a longer reply? Just dictate!

A few more reasons to love Spark:

See all of your important email at a glance, with a unified inbox which knows the difference between a personal email, a notification and a newsletter.

Use natural language to search through your emails. Type "attachments from Alex last week" to see all the emails sent to you last week by Alex with an attachment.

Spark will automatically find your most used signatures. So you can quickly swipe between them when composing an email, to choose the one that's best suited.

Integrate Spark with tools like Google Drive, Dropbox, Box, OneDrive, Readability, Pocket, Evernote and OneNote to easily attach files from these services to your emails.

Let your friends and colleagues quickly know what you thought about their email with one tap to send a "Like", "Thanks" or any other custom reply.

Enable Smart Notifications to only be disturbed by emails you care about.

Save attachments to iCloud Drive, Google Drive, Dropbox, OneDrive, Readability, Pocket, Evernote, OneNote or any application on your iPhone and iPad.

Need to refer to an email at a later date? Save it as a PDF to view later on your iPhone or save it to the cloud to access anywhere.

Customize Spark's widgets and sidebars to match your workflow.

Add the calendar widget to quickly see all of your event invitations at a glance. Respond to invitations and save them to your phone's calendar with just a tap.

Quickly manage and reply to your emails from your wrist. Tap one of our quick responses or dictate a longer message, all while your phone stays in your pocket.

Sparks is designed to look great on your iPhone, iPad and Apple Watch. The content of your emails is always the priority.

We've spent over 18 months sweating every detail and interaction of Spark. We hope that you'll love using it as much as we loved making it!

You are going to like your email again.

Editors' Notes

Wake up and check your inbox. You’re off to a good start!

Very good app overall. A few bugs

Mr Edward

Have been using this app since soon after the initial release. Overall it outperforms any other email client I have used for iOS, and is enjoyable to use.
The layout and user interface work well, and updates have progressively improved the app (one recent example was the way emptying the deleted mail went from being a process with a prolonged continually refreshing icon (until complete), to an immediate process with background action from the server.
The standout unique feature from my perspective is the predictive filing system, which automatically shows the most likely folders to choose from when moving items from the inbox to a folder.
Bugs have included draft emails intermittently closing whilst writing them - this seems to have mostly stopped with this version. Also calendar events which extend beyond midnight - such as shift work - don’t display correctly (sometimes as two separate items in the wrong position on the calendar despite showing the correct time, or just displayed as all day events instead of correctly displaying as a time period). Still - having a combined calendar is useful.

Great all rounder email client for demanding needs

Kunal Basu

I've been using Spark for quite a few months now. I've found this to be quite easy to use and dependable - it displays the conversation threads beautifully so that it's easy to get the complete story quickly just scrolling up and down when one has only few moments to spare.

The app can bring your multiple accounts in one place and can use a smart email box feature to filter out the important conversations for your convenience. Personally I have preferred to use the more conventional mailbox by mailbox view though but that was more of a personal preference. I used the pin function too so that I keep an eye on the important conversations.

I specially liked one feature that was quite useful for me - it's the delayed delivery of your emails. I have used this extensively and it works like a charm. For my particular requirement, I don't want to send my recipients emails over the weekend however I generally clean up my inbox over the weekend (weekly review those of you are familiar with GTD). This feature is a lifesaver for me.

Great job guys! Keep up the great work.
