`validate_email`

Pack: disify · Endpoint: https://gateway.pipeworx.io/disify/mcp

Verify an email address is properly formatted, has valid DNS records, and isn’t disposable or an alias. Returns validation status, a 0-100 confidence score and the signals behind it. Pass your own Disify key as _apiKey — the keyless anonymous quota is shared and usually spent.

Parameters

Name	Type	Required	Description
`email`	string	yes	The email address to validate.
`_apiKey`	string	no	Optional but recommended: your own Disify API key (BYO — Pipeworx does not supply one). Without it the call uses the anonymous tier, whose daily quota is shared across all Pipeworx callers and is usually exhausted. Get one at disify.com.
