I'd like to hide the "Starter Templates" that are offered when a person creates an email, and only show "My Templates" - is this possible?
Yes, it's possible. Go to Admin > Email > Edit Email Editor Settings and uncheck Enable Marketo Starter Templates.
Would be much better if this was a role, rather than a global on-off.
votre here: Editor 2.0: access to the Starter Templates to be controlled through a role permission
Will hiding them make them unavailable altogether? Is it possible to have "My Templates" be the initial tab that shows instead?
