## Topic Overview
An email address can look normal and still be risky. This 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 tool 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 the Tool 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 result separates invalid, risky, and likely usable addresses and explains exactly what to fix before sending.

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

No browser-based checker can reliably prove mailbox existence without contacting the receiving mail server. This tool checks 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 checker runs in the browser and does not save the address to Mailrith.
