If your current email is on your own domain, you can! Just a DNS change and a few configuration steps and all new messages land in your new inbox. If you have something like gmail or outlook, then you can still do it with a simple configuration change there to forward emails. On gmail I know you can create filters (rules) to forward to different inboxes even, so current subscriptions could land in different Clova inboxes. Email me at support at clova dot email and I'll guide you through some options.
