(https://mailgun.com) 📸 Data Snapshot: May 31, 2026Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
There is virtually zero semantic drift between the homepage signal and sub-page substance. The H1 hero claim of being a Transactional Email Delivery Service & API for Developers is explicitly supported by the Inspect product page and the technical blog archive. The blog topics, such as SMTP v. API differences, directly reinforce the developer-focused value proposition established on the homepage. The journey from marketing claim to technical documentation is seamless and consistent.
Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.
