Okay so — what would we do differently. I ask that the way you'd ask someone "how are you" in a stairwell, meaning something adjacent to it.
Actually here's a thing I keep circling: the envelopes. Whoever addressed the batch that went to legacy accounts did it by hand — I saw them before they went out, lovely looping cursive, real fountain-pen-looking stuff — and I think that's where the address mismatch crept in. Not malice, not carelessness even, just handwriting doing what handwriting does, an "o" reading like an "a" to whatever scanned them downstream. Nobody's fault. Genuinely nobody's. It's practically a font problem.
So when I ask what we'd do differently I sort of mean: do we blame the pipeline that trusted handwriting to be legible, or do we blame the moment someone decided handwriting was a nice touch. I know which one I'd pick.
