Hi! Thanks for reaching out. Your login email is your account identity, so there's no self-service field to change it directly in the app. The easiest way is to move your access to the new email:
Go to Settings → Members, invite your new email to the same workspace, sign in with it, transfer the "owner" role to it if needed, and then remove the old member. All your team data — credits, subscription and saved searches — stays with the workspace, so nothing is lost.
Let me know if you'd like a hand with any of the steps!
