About 1,000 — look, keep, delete or move — once you trust the rules (blurry goes, duplicates go, 'maybe' gets one folder). The keeper instinct is the bottleneck, not the speed: most people would delete 70-80% of their photos if the decision felt safe, and a backup is what makes it feel safe.

Much faster — email has select-all searches. 'Older than 2 years', 'newsletters' and 'notifications' each clear thousands in minutes, which is why the rate is about 5,000 emails an hour against 1,000 photos. Do email on a laptop with a real screen and the delete key earns its keep.

Everything you are about to prune — one full backup of photos, files and email makes every deletion decision ten times easier, because the worst case stops being permanent. Cloud sync alone is not a backup if deletions sync too; use a snapshot or an external drive, then prune freely.
