Email Storage and Backups.
Spark is an email client which allows users to connect to an unlimited number of IMAP or EWS email accounts. Whenever you check your inbox, Spark contacts the server to connect you with your messages. When you read an email message, you aren't actually downloading or storing it on your device; instead, you’re reading it off of the server.Read More Helpful
