Week of 7 November 2026 (ISO week 45) · Measured 7 November 2026 · Compared with 1 November 2026 · By the Mention Impossible team
Takeaway. No platform dominates. Mailchimp was named in 21 of 40 email marketing answers (up from 15 on 1 November), Klaviyo in 20 and ActiveCampaign in 18. Mailchimp's six-answer gain came in Perplexity (9 of 24, from 6), Gemini (7 of 8, from 5) and Claude (4 of 4, from 3); ChatGPT was unchanged at 1 of 4. The most-cited domain was mailercloud.com (13 of 40 answers), which is not a tracked brand in this category.
Read with care. Samples are small (n = 40 answers in this category; ChatGPT and Claude contribute 4 each) and changes are not significance-tested. One week compared with one week is not a trend. Pooled figures weight Perplexity most (24 of 40). API answers can differ from the consumer apps.
