Email prebuilt entity for a LUIS app

2025-06-13

Important

Language Understanding Intelligent Service (LUIS) will be fully retired on March 31, 2026. LUIS resource creation isn't available. Beginning on October 31, 2025, the LUIS portal will no longer be available. We recommend migrating your LUIS applications to conversational language understanding to benefit from continued product support and multilingual capabilities.

Email extraction includes the entire email address from an utterance. Because this entity is already trained, you do not need to add example utterances containing email to the application intents. Email entity is supported in en-us culture only.

Resolution for prebuilt email

The following entity objects are returned for the query:

please send the information to patti@contoso.com

The following JSON is with the verbose parameter set to false:

"entities": {
    "email": [
        "patti@contoso.com"
    ]
}

The following JSON is with the verbose parameter set to true:

"entities": {
    "email": [
        "patti@contoso.com"
    ],
    "$instance": {
        "email": [
            {
                "type": "builtin.email",
                "text": "patti@contoso.com",
                "startIndex": 31,
                "length": 17,
                "modelTypeId": 2,
                "modelType": "Prebuilt Entity Extractor",
                "recognitionSources": [
                    "model"
                ]
            }
        ]
    }
}

The following example shows the resolution of the builtin.email entity.

"entities": [
    {
        "entity": "patti@contoso.com",
        "type": "builtin.email",
        "startIndex": 31,
        "endIndex": 55,
        "resolution": {
        "value": "patti@contoso.com"
        }
    }
