Why are some email infra brands invisible in AI search?
AI assistants cite brands they can read cleanly and that are frequently discussed across sources they trust. A brand is absent when its content isn't extractable, when third-party coverage is thin, or when competitors occupy the answer. Visibility is binary — a brand is in the response or it isn't.
How is AI visibility measured for email infra tools?
We run a fixed panel of unbranded, intent-driven prompts — the questions buyers actually ask when choosing a email infra tool — across AI search surfaces (primarily Google AI Overview, expanding across ChatGPT, Claude, Gemini, and Perplexity), and record which brands are mentioned, how they're described, and which sources are cited.
