Check Email Addresses In Bulk

mailcheck.check_emails

Start a batch check over many addresses; the result arrives later.

Configuration

1 field, 1 required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.

FieldTypeRequiredDefaultConstraintsExample
emails
The addresses to check, as a JSON array or a comma-separated list.
arrayYes—≥ 1 characters; array of string["jane@example.com","john@example.com"]

Example configuration

Every value below is the contract’s own example or default — nothing invented.

{
  "emails": [
    "jane@example.com",
    "john@example.com"
  ]
}

Output

One shape.

Notes

  • The batch runs asynchronously: poll mailcheck.get_operation with the returned name until 'done' is true, then read 'result_url'.

See Check Email Addresses In Bulk run in a workflow.

In a technical demo we add the Mailcheck connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
