Spark is available on different platforms, and you can enjoy Spark’s features on the multiple devices you own. Spark allows you to sync your accounts and preferences when you log in to a new device. Since it’s a hassle to add your email accounts one by one, Spark gives you the ability to sign in with your primary account, and every other account automatically logs in for you.
After downloading and launching Spark, log in with your personal or work email address. This address becomes your email for sync. When you want to use Spark on a new device, log in with this address. It syncs your personal settings and the email accounts you’ve previously added to Spark.
We recommend you to use for sync the email account only you have access to. Don’t use the email address shared between multiple people as an email for sync. For instance, the email address your company uses for customer support or client communication. It’s better to log into Spark with your personal or work email and then add the other accounts (Mac|iOS)
When you log out from your email for sync, the other accounts you previously added to Spark automatically sign out from this device as well.
