Which email client software does AI actually recommend?

We asked ChatGPT + Gemini the questions a real buyer asks — starting with best email client software — and counted how often each of 5 brands got named.

No brand names in the questions. If a company shows up, it earned it.

How this was measured

  • Every brand was asked the same set of neutral email client software questions — never containing the brand's own name, and never naming a competitor.
  • The score weights how often the brand appeared (50%), how high it ranked (30%), and how positively it was described (20%).
  • Matching is whole-word, and an answer saying it has never heard of a brand does not count as a mention.
  • AI answers vary between runs, so every question is asked more than once and a brand only counts as named when the majority of runs name it.
