Orbator asked ChatGPT, Perplexity, Gemini, Claude and Grok buyer questions about email marketing for nonprofits and sampled 38 answers between Aug 21, 2026 and Sep 18, 2026. Recommendation share counts the answers that recommended or listed a product, so a passing mention or a warning adds nothing to it. A category publishes once it holds at least 20 independently sampled answers in the window. Read the full methodology or download this ranking as CSV.

Reading the numbers: Share is a point estimate on 38 sampled answers, so each row also shows its 95% CI — the Wilson score interval around that share. When two products' intervals overlap, the gap between them isn't statistically meaningful at this sample size. First pick is the share of a product's recommending answers where it was named first, which separates “always mentioned” from “usually the top recommendation”. Full methodology.
