Count who fills one folder of a mailbox, the inbox unless folder names another, before clearing it out by sender - newsletters, promotions and notifications a group at a time rather than thread by thread, each group sweeps_apply moves once the person approves it; nothing is moved. The answer numbers the 20 senders with the most mail there, each with its count, how many are unread, its newest and oldest dates, two of its subjects, and heldApart: how many are receipts, orders, bookings, bills, account or security notices. otherSenders and otherMessages count the rest, and nextSenders names the next 20 of them by address with how many messages each has, for another preview to name in senders. A sender whose name screens as a prompt attack is withheld with its group, which takes no number, counted under withheldSenders and withheldMessages; a subject that does leaves its group's subjects, counted under withheldSubjects; a next sender's address that does leaves nextSenders, counted under withheldNextSenders. Flagged mail, drafts, the person's own messages, mail from people they write to, and everything in sent, drafts, deleted or junk is in no group, counted under leftOut instead. At most the newest 10,000 messages of an Outlook folder, or of a mailbox held by its password, are read, and notReadBefore names the date before which a larger folder was not. A mailbox held by its password is cleared out only where its mail server names where it moves each message, and a Gmail held by its password out of its inbox alone. Gmail allows few reads a minute, so only the newest 150 of a Gmail folder are read: they choose the groups, and each group's messages then counts all its sender's mail the preview asks for, up to 10,000 in all, unless the preview narrows by subject; its other figures, otherSenders, otherMessages, nextSenders and leftOut count the messages read, and folderTotal is Gmail's own estimate. actionsLeft is how many actions this account has left in its daily allowance after this call. sweep is the handle sweeps_apply clears what was counted by, held an hour; what an apply moves can be put back until putBackUntil at the earliest. The times it answers with carry their offset in the person's own time zone, which the answer names under now beside their time now in it - UTC where the person has stored no zone, as now says.
