Popular email app Spark for Mac and iOS was today updated with several new features aimed at professionals, including "Send Later" and "Follow-up Reminders."

spark
Send Later is designed to allow users to schedule emails to be sent at a later time instead of right away. Spark users can compose an email and then schedule it at the time when it's most likely to be read.

The feature can be accessed by choosing the Send Later icon when composing an email, which will pop up an option to choose a time.

Follow-up reminders are meant to remind Spark users to follow up on emails that have been sent out and not responded to.

Professional follow-up is an art that both sender and recipient appreciate. Everyone gets busy and can easily miss important emails. In this case, friendly follow-up reminders help you get a response when the timing is right. Use follow-up Reminders in Spark to ensure that your message doesn't end up in limbo.

On iOS devices, the Spark app has been updated with a new email composer to accommodate the two new features. The new design is meant to make it easier to choose the From email address, and more explicit CC and BCC buttons are supposed to make it easier to manage CC/Bcc contacts.

The new Spark features are available today in both the iOS and Mac apps, which are free downloads. [iOS: Direct Link] [Mac: Direct Link]

This always happens. New shareware app that's lightweight, easy to use and much simpler than Gmail or Outlook

Then over the subsequent years, it gets bloated by adding all of those features back that made us ditch traditional clients to begin with.

then someone else comes along that's lightweight and we all switch to that.

I use mail.app. It's free and integrates with Exchange server for Calendar & contacts
I personally don't care how "easy" it is to use; I never used Mailbox and dont want a replacement for it. Features are good if done right.

The problem is different apps have different features right now and have their good parts and lacking. No one has stepped up and made the "best" email app.

The stock app works fine, if it wasnt for Apple's failure to play nice with Google and Gmail accounts. iOS rarely fetches accurately even at 15 min; Ive gone in and seen a last checked time easily 45 min before. So fetch is just pretty terrible in the stock app is the real kicker.

Again your full mail is not going through their servers, ...

"All general email activity is mostly done on your device. Our servers are only involved for delivering the push notifications and, in some cases, for sending your email messages (for example, when using Send Later functionality).

Accounts are added to Spark through OAuth where possible."

"Primary function of Spark servers is to send push notifications and badge numbers to your device. To do that, Spark servers download email headers and text parts from your email service provider and use them to compose push notifications. We delete email headers and text as soon as push message has been prepared and sent. We store messages and emails in encrypted form on secure cloud-based servers."
If you do "Send Later", you store the entire outbound message on their server. Before you freak out, I'm aware that #1 they have no interest in keeping it, and #2 it behooves them to keep it securely.

Text "parts"... ok. Maybe they just grab the first 250ch? I dunno... again, #1 and #2.

The last sentence is pretty clear though. "We store messages and emails" says that they clearly are dealing with complete messages a lot.

Am I still oversimplifying? Maybe for you Stu, but I think it's fair to say that you've done a good job in both pointing out the nuances of what third party mail apps do, as well as point out that, in fact, many times your full messages do go through Spark.

BUT I DON'T CARE ABOUT SPARK so much as I'm pointing out that ANY third-party email client on iOS has to get your password and log in as you to provide services. I'm not even declaring a moral evil here. I'm just saying that the disclosure of this kind of information is important. While you might be ok with this on a personal email account, maybe it's not such a good idea to use this on a sensitive account. Maybe, someone is going to assume that email is email on iPhone, and that this is a core service like a calendar/reminder, when it isn't like that.

But for what it's worth, thanks for pointing this stuff out. Now, if you go back to my first statement, "BTW, if you use a third party email app, you are giving the third party complete visibility to all your email and your password. What could possibly go wrong?" -- are you sure that's still oversimplified?

I know this sounds dumb, but I don’t use Spark because of the notification sound choices - either a loud garish spark one or an iOS sound that’s actually meant for app notifications not emails.

I’ve been using Airmail because of it, and Spark is much better.

Just give me a nice little ding like the default mail app or like Airmail. I’ve been asking them for 2 years now!

Yeah, the inability to properly customize notification sounds is very annoying. On the other hand, AFAIK Spark is the only mail client that allows you to collapse mail folders. Why this feature is not provided by default in any Mail client is beyond me. In summary, there is no perfect mail app, yet. A real shame.

Spark is second best to Edison Mail, however Edison Mail has no Watch app. Unfortunately the Spark Watch app still is iPhone dependant on the LTE Watch. Hopefully Spark will make the Watch app independent soon.

Apple should buy this company and make them default on Watch and iPhone. The current default apps are horrible.

I also use Spark as my default mail on macOS.
Edison, formerly Easilydo, was good but their threading methodology drives me nuts. The second screen list of thread bits and then have to click into each email or reply separately and back again to the list is counter-intuitive to the default mail app or Spark where the threads collapse and expand to view the conversation all on the same screen without having to dive into each bit and back.

Another issue I found is their snooze is on device only so if you snooze an email on the iphone and go to say Gmail on the web (or Outlook on your PC) the email is still in your inbox; not moved to a snooze folder like spark and other email apps to reappear later.

Those 2 major issues keep me from using it. I do like the attachments at the top of the email like the Outlook app does. It's a little "basic" in terms of features if you don't use the assistant stuff.

I also had some issues in search that it wasnt finding all emails that Spark does really well.

But Spark has disappointed me in general. It started off really good (it's still really good) and then got stale for about a year now with nothing but bug fixes besides drag and drop for ipad. There was a 6 month period with a single app update to it. These are the first major new features for iphones in a long time, and it's still missing a lot of stuff. It drive me absolutely nuts that Spark has no edge swipe to get to the side menu like Outlook and Edison; getting to that top left on a Plus device is not fun one handed.

Outlook was the black sheep to me for a long time; it did nothing very well. Im not all keen on the social media esque redesign but the search and features are starting to get a LOT better and updated weekly. It's missing a lot of customization though, even simple things like in-app browser though.

Really I have yet to find a really good 3rd party email app. Airmail was the closest but a buggy mess that seems they will never fix up to a stable state.
