What's New

Version 2.0.13

Mojave support is here with new simplified conference call scheduling in Spark and more!
## New
- Spark now integrates with most popular conference call services like GoToMeeting, Google Hangouts, Google Meet, and Zoom. You can add conference call link to any event without ever leaving Spark. Just log in to the service of your choice and add links with one click when you create or edit an event - highly recommend for the busiest of us!
- Welcome the dark side of macOS Mojave! Spark fully supports new Dark Mode and will turn it on as soon as you enable it in Settings -> General. Upgrade, turn it on, and let us know what side you’re on!
- Along with Dark Mode support, Spark now has better-organized Preferences menu that should help you find what you’re looking for faster: Account section has color coding for each account, Swipe Actions are better explained with nice visuals, Services just look better with the new design.

## Fixed
- When opening Move, focus will be put inside search field to help you find the right folder without taking your hands off the keyboard. It’s a long time requested improvement and it’s finally here.
- We’ve also brought back an option to automatically collapse older messages inside the thread. All of us have different preferences, so we added this option in Preferences -> General to let you choose the way you want Spark to behave.

We hope you enjoy this release.

New to Spark, but…..


I use several email clients due to work, my own business, personal, etc. To say I despise the Gmail format is an understatement, so I was looking for something relatively user friendly, streamlined, and fast to manage, as I have planned to incorporate all these emails into one client by “forwarding.” I am trying Spark after using Outlook for yeasrs. I like a lot of the customization of Spark, but where it shines for me is the ability to customize the “swipe” feature. I can move emails around immediately without going to the ribbon IF I customize it to suit my own needs.

Yes, you have to take some time to learn the mechanics of it, and yes you have to customize it, and YES it’s a learning curve (albeit not a steep one). I’ve had it for less than two weeks and the only bit I don’t use yet is where I might connect it to a “note” app. For me, I would have liked to see a “Notes” feature inside Sperk to activate shoudl I choose instead of using one of these other programs, but I get that this would work for many folks…..I’m not one of them, though, as my notes are really quick and short (think stickies more than notebook notes).

That said, it’s not a heavy user program, IMO. It’s for those of us with short message needs and to keep our heads above water with all our clients. In that, I think it’ll be a keeper. (and let’s face it….ANYTHING is better than the Mac’s mail app—or at least I think so).

Near painless email

Herb 2111

There is so much right with this program that I would gladly pay, and pay a lot, for it--the fact that's free is hard to believe. I use it on all platforms--phone, tablet, desktop, laptop-and it finally cured me of POP. I used to create a lot of categories and tags with my old programs (Postbox--prior to that Thunderbird--prior to that Mail) so as to keep track of things, but the search function in Spark is so robust that I don't have to now--I use gmail, which keeps an archive, and Spark searches it seemingly instantly.

Somehow everything is quicker with Spark, and simpler. I can follow the threads now--that always confused me in Postbox. I use the "send later" function, which I find essential, and which is an add on in Thunderbird and Postbox--but it's built right in to Spark--thank goodness, because I couldn't do without it.

I could go on and on. One thing I miss--in Postbox I could resize any graphic by clicking and dragging. In Spark you can reduce graphics, but you have to pick a size--small, medium, or large. That's the only thing I miss--but the tradeoff is well worth it. I spend a lot less time on email now. One more thing--I was constantly looking up how to do things in the manual of my old program--I don't even know if there is a Spark manual--but I seem fine without it--truly amazing.

Killer Quirks overshadow solid features


For my work email I tried using Outlook but found it too buggy and wouldn’t talk to my calendars. I tried the built-in Apple Mail but found its attachment handlign was highly problematic for my windows friends. When I found Spark I thought my search was over. Overall the app does email really well, with useful features like snooze and Smart Inbox and a clean user interface. However there are some quirks that are really getting in the way.

Spark recently added a calendar feature, but it won’t integrate with the calendars on Apple’s Calendar app. The end result is that when I receive calendar invites through email Spark intercepts them and won’t let me add them to my calendars (which are not associated with my email accounts). Just the ability to turn this off would solve this error.

Contact management is problematic. I needed to remove some old contacts from Spark but there is no easy way to do this. When I start typing an email address the old addresses pop up first, and there isn’t an option to remove them. Give me this option! Spark suggested I remove all messages to/from this person, and I have, but their email address persists in the autocomplete. I have accidentally sent multiple emails to the incorrect person because of this. Give me the option to remove this contact.
