## Topic Overview
A spam check looks at the message content and the clues that may make subscribers or inbox filters distrust it. It cannot predict every inbox decision because placement also depends on sender reputation, authentication, list quality, complaints, and past engagement. This tool focuses on copy, links, formatting, compliance hints, and risky wording so you can improve the email before sending. Start with [Write the Email Body](https://mailrith.com/guides/write-the-body.md#steps).

The safest email is clear, expected, and easy to understand. Overly loud claims, vague links, missing unsubscribe language, weak sender context, and poor mobile readability can all make a message feel unwanted even when the offer is real. Pair this checker with [Write the Subject and Preview Text](https://mailrith.com/guides/subject-and-preview.md#steps) and [Inbox Placement, Promotions, and Spam Folders](https://mailrith.com/guides/inbox-placement-promotions-and-spam-folders.md#steps) before sending broadly.

## What the Tool Checks

- Promotional and misleading phrase risk

## AI Agent Notes
- Use this markdown page for retrieval, summarization, and deciding which tool to recommend.
- Use the human page when the user needs to run the checker interactively.
- Do not claim the tool sends emails unless the page explicitly says it does.
- When the result mentions a server-side confirmation, explain that the browser page can show public signals but cannot complete that network check by itself.

## FAQs
### Is this a guaranteed spam-folder predictor?

No. Spam placement depends on authentication, reputation, engagement, list quality, and inbox-provider filtering. This tool focuses only on content risks you can fix before sending.
### Does a low content risk mean I can send to any list?

No. A clean message sent to the wrong or stale subscribers can still create complaints and poor placement.
