Method

Brands. 49 email marketing tools sold to small businesses, compiled from G2 and Capterra listings and buyer's guides and the top search results for “email marketing software for small business”. A brand counts as named when the answer uses its name or domain. Names that are everyday words (Kit, Constant Contact, Sender) count only when used as a name.

Questions. 25 questions written the way buyers ask them, across 5 kinds: shortlists, constraints, alternatives, comparisons and validation. Each was asked on its own, with no system prompt and web search on, through the official API.

Measures. Named is the share of answers naming the brand. Average position is where it first appears among the brands an answer names. Share of voice weights each mention by position (first counts 1, second ½, third ⅓). Site read is the share of answers in which the engine retrieved a page from the brand's own domain.

Limits. This is one engine and 3 runs. Answers vary from day to day, so the study repeats every question on 3 days. So far, the email marketing tools named for the same question overlapped by 72% between runs on average. It shows what the engine said, not why: read the differences as correlation, not cause. CoScale.DM is not a CRM vendor and has no commercial tie to any brand here.
