1. Yes, only @owlmail.io domains for now. But, Owl Mail will allow for custom domains soon. 2. An upcoming feature will enable the creation of sender 'allow' and 'deny' lists for each Owl Mail address (With default sender 'allow' lists for top sites). Currently I track my account credentials in a password manager. A browser extension is also on Owl Mail's roadmap.
