Bulk-update senders
Apply ONE patch to MANY mailboxes at once, in a single call: pacing (dailyLimit, minGapMinutes), lifecycle (pause/resume via state), warmup, or operator labels. Use this whenever the same change goes to several senders (e.g. ‘set every sender to 50/day’, ‘pause all senders’) INSTEAD of calling update once per mailbox. It cannot change credentials or transport, so it never sends a verification email. Returns how many updated plus any per-mailbox errors. Note: a mailbox has NO per-mailbox clock-time send window for campaigns — the daily sending window and timezone belong to the CAMPAIGN (program), so ‘make each sender send at a different hour’ means splitting senders across campaigns with different windows, not a sender edit.
