When a check finishes, every address in your list gets a clear, color-coded label so you know what to do with it.
| Label | Meaning | What to do |
|---|---|---|
| Safe to send | The address is real and accepting mail. | Send with confidence. |
| Risky | Something is uncertain about this address. | Send carefully, or hold it back. |
| Do not send | The address is not real or will bounce. | Remove it from your list. |
| Unknown | We could not get a clear answer this time. | Try checking it again later. |
Each address also shows a short, plain-English reason (for example, "Mailbox does not exist" or "Accepts any address") and a confidence score, so you always know why it got its label.
