Probably not hacked but you can check this yourself:
Login to your online account:
https://skyid.sky.com/signin/email/
Go to Settings (the screw icon on the right hand side) > More Settings > Filters and remove anything that you did not setup.
Then go to Settings > More Settings > Mailboxes > Your email address > Reply-to address
And again remove anything here that you did not setup.
If everything looks OK then see if you can put in a request to get them returned:

If they are restored then it would be advisable not to store all your emails in your inbox if this is where they were located, but instead set up separate folders to keep them in.
