EmailListPageAn EmailListPage object is one page of results from puter.email.list().
items (Array)
An array of EmailSummary objects, newest first.
cursor (String) (optional)
A pagination cursor for the next page. Present only while more pages exist. Pass it as cursor to the next puter.email.list() call to continue.
A page may hold fewer than limit items while cursor is still present — always iterate until cursor is absent rather than checking the page size.
