Who Shouldn't Use Spark?

If you are a VC, investor, or professional who deals with a ton of email and a lot of intros, we'd recommend considering Superhuman Mail instead. Superhuman offers a premier email experience that is the best in class (and is what we've used here at Efficient App for over 6 years). Superhuman has gone that extra mile with each feature, and for professionals who live in their inbox, we say the extra TLC is worth the extra cost. Read our full Superhuman Mail Review.

What Are Some Spark Mail Limitations?

Some users report that the performance of Spark Email can be a little touch and go. Users report that since the update to Spark 3, the app has become more slow and unreliable with a bit of crashing. Another complaint we've heard is that Spark sometimes makes mistakes when classifying emails that are notifications as newsletters, and vice versa, but that isn't something we're too worried about as you can easily correct Spark by letting it know the right category for the future.
