I am very new to Mac. I was previously using Apple Mail. It downloaded all my mails to a local directory (> 1 GB). Now I have switched to Spark and added two of my major mail accounts in Spark. before doing this I removed (unchecked only Mail option) those two accounts from Apple Mail client. What I am worrying is as I am not using the previous mail client the previously downloaded mails should not eat up my storage. But I still see there are mails downloaded in my storage.

Now are they mails previously downloaded by Apple Mail client or they belongs to spark ? If they belong to the previous client how should I remove it ? is it safe to just delete them all ?
