## 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. The email spam checker 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 the email spam 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.

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

No. Spam placement depends on authentication, reputation, engagement, list quality, and inbox-provider filtering. The email spam checker 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.
