Has changed my outlook on email
THANK YOU!!!!! I’ve been using spark for a few weeks now and I’m in love. I knew what I wanted from an email client but I thought it didn’t exist. I wished I would’ve been using spark YEARS ago. So many emails were getting lost because of my lack of motivation for email and now I’m back in business. I’ve always wanted to be a zero inbox kind of person but the task was so overwhelming. Spark has made it easy and I’m much more focused. I love the snooze feature because before I sometimes needed time to think about a response but I inevitably the email got lost. I’m a business owner so I should respond to emails in a timely way so this has really helped me retain more clients and keep up with email tasks. This really helps me focus when I get interrupted with an email or just need a little more time to think about my response but don’t want to forget about responding (which is what use to happen!) I also love how I can schedule my emails to look more professional sending them more at “business hours”. Email use to be this scary and terrible thing that I had to do, now it really is fun and enjoyable.

Snooze is Broken
Spark is generally great, when it works. However, snooze is perpetually broken. In prior versions, large numbers of snoozed items would lose their snooze date and revert to “someday”, forcing a periodic review of the snoozed folder to ensure nothing had gone AWOL. Now, snoozed items randomly appear at the top of the inbox immediately after being snoozed, labeled with their correct snooze date, or randomly appear in the inbox based on their original unsnoozed date with no indication they were ever snoozed. The latter is particularly bad, as there’s no way to know when this happens other than to keep the inbox empty or to remember everything that was snoozed and to notice when emails don’t reappear on schedule; if I could do that, I wouldn’t need snooze in the first place.
Spark typically works well enough and often enough that my periodic reviews of potentially less buggy alternatives always lead me back to Spark, but the continuing snooze bugs are very, very frustrating.
The bug appears to be correlated with having multiple devices running Spark and possibly taking Spark out of the foreground on iOS or closing it on macOS without first forcing a synchronization. However, religiously forcing synchronization doesn’t make the problem go away entirely. Avoiding using Spark on iOS while it is open on macOS also seems to help, as does avoiding using Spark on multiple devices altogether. It’s almost certainly a multi-client synchronization bug of some type.
Spark was great - now it’s not
I’ve used Spark for the past 3 years. I have 5 e-mail addresses because I am a teacher at several schools and a law student. I turned to Spark to better organize my email. However, I now dread having to open the app every morning. My “flagged” emails are overflowing. My “seen” emails are overflowing. I can’t figure out how to unsubscribe from emails without having to physically go into each email to click “Unsubscribe”. The app does NOT sync between iPad, iPhone, and Mac which is frustrating because if you delete emails on your iPhone you can then expect to see them UNREAD when you check your email on your Mac. Email signatures that you create on your iPhone will not sync to your Mac or iPad. Also, if you do not use your iPad for a week (Spark installed) - you will be inundated with zombie emails that were replied to or deleted already. Additionally, there’s no option to create email lists/groups. This is frustrating because as a teacher I like to create email lists of my students. Aside from that my Smart folder is unorganized. Emails marked as spam still come through to my inbox. The added team features are just unnecessary bells and whistles. I’m in the process of transferring my emails to Edison Mail. Spark has become headache.

Hi Amanda! Thank you so much for such a thorough review and we are sorry that you experienced such issues with Spark. Would you mind contacting us at email@example.com at so that we can investigate the sync issues you mentioned?
We will also do our best to find a solution for an overflowing inbox. As for creating email lists and batch unsubscribe feature - indeed, it is not yet available, we will consider adding this functionality. Thank you in advance!
