If you have a permanent computer with an email client on with your email account on , if this has filters , Spark will show just the Headers of new emails , than you have to go in the folder specified by the computer filter to read the whole email. Anyway it's free so it has a great value for that.
Good but can be better

Minus: lack of filter documents attached from cloud. These are only in alphabetical order, no search option. If you have hundreds of documents is hard to find the needed one to attach.Later edit: I used the app for at least two years and it looks to be the best app for me, five stars. Suddenly, I cannot send mails anymore, from my company account. From gmail and yahoo accounts I can send. I tried to uninstall the app and install again, but with no succes. Error: "A stable connection to the server could not be established". I'm very disapointed, because I was addicted to Spark.
