Third-party coverage is doing more of the work shaping how AI describes Postmark than Postmark's own pages — a typical pattern for brands without a tight content strategy on their site. What to do about it ## How Postmark can change how AI describes it Postmark already appears in AI answers, so the work is about prominence and accuracy — moving from "mentioned" to "recommended," and making sure the framing is the one Postmark would choose. Three levers do most of the work: 1. 01**Be extractable.** Publish answers to real Email Infra buyer questions in clean, self-contained passages a retrieval layer can lift without guessing. See [how to optimize for AI citation](https://lynceus.app/how-to-optimize-for-ai-citation/). 2. 02**Earn the right citations.** AI assistants quote sources they trust. Getting onto the third-party roundups and reviews they already cite moves the needle more than on-site changes alone. 3. 03**Measure, don't guess.** Track Postmark's [share of paragraph](https://lynceus.app/share-of-paragraph/) across assistants over time so you know which changes actually shifted the answer. See [how to measure AI visibility](https://lynceus.app/how-to-measure-ai-visibility/). How we measured this ## The methodology behind this report This report is built from a fixed panel of category-recommendation and brand-research prompts — the kinds of questions a real buyer asks when researching Email Infra tools. We run them across AI search surfaces (primarily Google AI Overview, with coverage expanding across ChatGPT, Claude, Gemini, and Perplexity) and record every time Postmark is mentioned, how it is characterized, and which sources the assistant cites. A "mention" means Postmark appeared by name in the answer; sentiment reflects how positively it was framed. We don't inflate counts with branded queries where a brand is guaranteed to appear — the panel is built around unbranded, intent-driven prompts where the assistant chooses who to surface.
