It's not possible right now to change your email or transfer your Playbooks in bulk. ‍But it is possible to transfer them one by one. There are 2 ways. 1. Share the playbooks from one account to the other. You can do this by having 2 chrome profiles. 2. Or export/import the playbooks from the Settings page. The biggest limitation is you won't be able to edit the scraper templates from shared playbooks.
