Getting Closer To Being “Just Right…."

The Builder....

Well…. I’ve now been using Spark for Mac since it first came forth on the Mac several months ago. Spark continues to be very stable and useful. And now, with the color categorization of email accounts, and the addition of the Send Later & Reminders feature, it makes the app even more useful. Also, you have the flexibility of changing your keyboard shortcuts to one key in many instances, which has proven to be very, very useful. Now, I will admit: For now, I’m still using Airmail because they have Read Receipts, so once Readdle initiates that feature, I KNOW I’ll be switching over to Spark for good.

Secondly (and this one puts Spark above all the rest): The biggest reason why I’m using Spark is because I’m not receiving notifications of every single email that comes my way!!! The makers of Spark have found some kind of way to only notify you of emails that come from REAL PEOPLE, which has proven to be a serious help during the day! So, when a REAL PERSON sends me an email, I get notified about it, while all the other emails just come forth into the app in the form of notifications or newsletters (important tip: Be sure to set the “Application Badge” to “Whole Inbox” so you can see that you have received the other emails).

All in all, this is a very, very good app. All they need is Read Receipts, and we’ll be home free!!

Great email app with tremendous custommer support team


I’m a Mac user that needs to have an email app that works on all Apple platforms. I’ve used nearly all the major ones, including Airmail—which I stopped using after it stopped rendering email content from several sources, including the Washington Post and others. I repeatedly brought it to their attention and they couldn’t fix it. I have been using Spark for Mac/iPhone/iPad for several months now and fiund it to be a truly outstanding product. It is nearly perfect but could use a few more functions, like being able to copy an email to a folder rather than move it, or having a range of notification sounds rather than two. What impresses me the most is their awesome support team. I recently had a problem with snoozed emails coming back to the Inbox before their time. I emailed their support team and they worked on the issued diligently and came up with a fix, all the while keeping me informed. They are a class act, whioch is why I buy Readdle products. As long as they keep paying attention to customers I’ll stick with them.

Love Spark, but: Poor Support, Increasing bugs

C Warren

I do love Spark for its UI, its use of favorites, and what used to be a seamless, bugless experience. But the bugs have been creeping in (link rendering in compose window, in-app browser perfomance, inconsistence push performance, others). And I expect a bug here and there, but the most troubling thing has been a gradual dropoff in Readdle’s support. I used to be able to correspond with their support staff, get answers or suggestions, and that kind of support feels good. But now when you contact support, you get a message that their “small but mighty” support team might get back to you and they might not. That’s a case where any appreciation of their honesty is undermined by a clever attempt at humor. It’s like calling the fire department and them saying, we’re a small but might firehouse, and we might not respond to your call for help. Wait and see. I use a heck of a lot of their software and Spark is the only app that’s slipping; it’s also the one for which (arguably) they’ve received the most positive press. I don’t like writing negative reviews, but sometimes that’s the only way to get the developers’ attention. I’ve tried several times recently via more conventional means. Crickets.
