Spark - fast and smart email for your iPhone


Spark makes it easy to work 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 fun, friendly and fully customizable!

"Spark is the smartest and most versatile email app for iPhone I've ever used."
***Federico Viticci. MacStories.

"This is the best iOS email app I've ever used. Buy it buy it buy it."

Smart Inbox automatically detects if an email is personal, a notification or a newsletter and groups it with similar emails for easy processing. 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 a smile 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.

Quickly swipe between signatures when composing an email, to choose the one that's best suited.

Integrate Sparks 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 "Smile 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.

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.

Know when somebody has read your email with Read Receipts. Smart notifications let you know when they've read the email.

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 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.

Michael, What are your thoughts on my showstoppers comment for the Spark app?

:-( :-( :-( Showstoppers:
- no 2-factor authentication support for iCloud
- no email alias support Foor iCloud email accounts
That's lame but I'll point the Readdle guys to your comment. I don't use two-factor so I hadn't run into this.

What's alias support?
Fred Zelders replied:
Alias support means that you can define alias email addresses for a certain account. iCloud supports email aliases.

My formal iCloud/me account is zeldersfred @ but I use
f.zelders @ as my official email address. Besides that alias I have defined another alias. (Different aliases allow me to apply a different set of mail handling rules.)

Email clients that do not support email aliases, like Spark, do not allow that I send an email originating from f.zelders @ and do not allow to reply with that alias address.

P.S. I hope you understand what I mean. English is not my native language.

I think I understand. I will let the developer know. You might want to bookmark this so you get updates on its development.

I'd like it if I could turn off the behavior to view by conversation. For some reason it thinks things are part of a conversation even when they are not. Irritating.

I just wish it hadn't crashed 10 times in the first 20 minutes I used it. I got fed up and deleted it.
