Classify emails automatically
Sorting incoming mail is the most profitable automation there is: repetitive, dull, and a machine does it just as well. Run the same email through eight models — GPT and Claude included — and compare.
What to look at when comparing
For classification, all that matters is that it picks the right category and does not invent a new one. A big model does not classify better than a small one — it just costs more. Watch for any that add explanations you did not ask for: those are tokens you pay for and never use.
