## Topic Overview
An email address can look normal and still be risky. The email checker looks at the address itself, the domain after the `@` sign, and common list-quality signals that often lead to bounces or weak engagement. It is most useful before manually adding a subscriber, checking a signup issue, or reviewing an address that looks suspicious. For a broader cleanup process, read [Protect List Quality](https://mailrith.com/guides/protect-list-quality.md#steps).

The email checker does not send a test email and does not prove that a private mailbox definitely exists. Instead, it explains whether the address is shaped correctly, whether the domain appears able to receive mail, whether the address may be disposable or role-based, and what to do next. If the result mentions bounces, use the [Bounces](https://mailrith.com/guides/bounces.md#steps) guide to understand why bad addresses can damage future sending.

## What Email Checker Checks
- Email format and length
- Domain spelling and typo suggestions
- Mail server records for the domain
- Disposable or temporary email domains
- Role-based inboxes such as info@ or support@
- Free mailbox services and risk notes

## Result Behavior
The check report labels the address as invalid, risky, or likely usable, then explains what to fix before sending.

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

## FAQs
### Can this prove a mailbox exists?

No browser-based email checker can reliably prove that a mailbox exists without contacting the receiving mail server. The email checker reviews the address format, domain, mail records, and common risk signals, then explains what still needs human review or confirmation from the receiving mail server.
### Does Mailrith store checked email addresses?

No. The email checker runs in the browser and does not save the address to Mailrith.
