Spark streamlines your mobile email experience with a unified inbox, smart searching and notifications, quick replies, and customizable widgets and toolbars.


Unified inbox: Spark gathers your Google, Yahoo, iCloud, and Outlook email in one place.

Expedited emailing: Your new emails are easy to see up top, divided into three categories: New, Notifications, and Newsletters. Once you read an email, it moves out of your way to the Inbox section at the bottom of the screen. Respond quickly to messages by clicking the Like, Thanks, or Smile button. End your responses with one of several signatures saved under Settings. In your message, swipe the signature line from left to right to cycle to the appropriate signature.

Calendar widget: With this handy feature, you can scan every emailed invitation you receive and transform each into a calendar entry.

Save for later: If you can't deal with a message now, click the clock button to snooze for later today, tomorrow, next week, someday, or the date of your choice. You can also pin more important emails to the pin page for later viewing.

Save as PDF: You can save email as a PDF, as well as printing, saving, moving, archiving, deleting, and marking it as spam.

Smart Search: Search for previous emails using natural language, such as typing "emails with picture attachments from last week.". In our tests, this feature worked perfectly.

Smart Notifications: With this feature enabled, Spark will notify you about only your most important messages.

Highly customizable: Under Settings, you can personalize your main widget. For example, you can make it sit at the top or bottom of the page, and include or not include immediate access to your calendar, attachments, smart folders, pins, and snoozed articles. You can also choose which sections (Inbox, Snoozed, Archive, Attachments, or Smart Inbox) you want to see in your sidebar and in which order.

Connected services: Click Connect to Services under Settings, then Accounts, to add your Dropbox, Google Drive, Box, OneDrive, Readability, Pocket, Evernote, OneNote, and or Instapaper accounts.


Miscategorizations: In our tests, certain notification emails, such as social media requests, often showed up under Newsletters.

Bottom Line

Spark helps you handle your many emails quickly and efficiently.

Developer's Description

Organize your mail easily.
Best of the App Store 2015" - Apple. "Spark is a fast, smart way to manage your email" - The Verge. "I've been using Spark for about a week and it's finally become my default mail client." - TechCrunch. "Spark is a new email app that does a lot right." - LifeHacker. 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: UNIFIED INBOX. 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. SMART SEARCH. 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. SIGNATURES. 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. INTEGRATIONS WITH SERVICES YOU USE. 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. QUICK REPLIES. 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. SMART NOTIFICATIONS. Enable Smart Notifications to only be disturbed by emails you care about. SAVE ATTACHMENTS. Save attachments to iCloud Drive, Google Drive, Dropbox, OneDrive, Readability, Pocket, Evernote, OneNote or any application on your iPhone and iPad. SAVE EMAILs AS PDFs. 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. CUSTOMIZATION AND PERSONALISATION. Customize Spark's widgets and sidebars to match your workflow. CALENDAR WIDGET. 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. APPLE WATCH APP. 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. GREAT DESIGN. Sparks is designed to look great on your iPhone, iPad and Apple Watch. The content of your emails is always the priority. ATTENTION TO DETAILS. 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.
