Variants of the address for checking that an app accepts valid but unusual email addresses and rejects invalid ones: delivered (capitals, plus tags with apostrophes and other special characters, the longest name allowed; mail to these arrives in this address’s inbox), undeliverable (valid by the standard but refused before they arrive) and invalid. See <https://proxymail.qa/docs/unusual-addresses>.

## Authorizations

- **[apiKey](https://proxymail.qa/docs/reference.html#apikey)**

## Parameters

### Path Parameters

**address**

required

string format: email

The test address, URL-encoded. A variant also works: capitals, or a +tag (k7f2x9ab12cd+o’[brien@mailclub.dev](mailto:brien@mailclub.dev)). It acts on the plain address; waiting on a +tag variant, or listing its messages, only finds mail sent to that variant.

#### Example 

```plaintext
k7f2x9ab12cd@mailclub.dev
```
