A regular got three review requests in one afternoon. How many follow-ups can one customer get?

One review request and one re-order nudge per number at a time, and at most two follow-ups per number in twenty four hours, however many orders they placed; a later order's follow-up is retired rather than sent on top. If you tick Also follow up on orders nobody marked delivered under Settings → Automations, an order nobody marked delivered is followed up once its completion timer runs out, with the same delays. A counter sale rung up with no phone number gets no follow-up at all. The Orders & delivery tab in the docs covers follow-ups.
