      description: The number of items in the list to skip over before starting to retrieve the items for the requested page. The default `offset` of `0` represents the beginning of the list, i.e. the start of the first page. To request the second page of the list, set the `offset` to the page size as determined by `limit`. Use multiples of the page size as your `offset` to request further consecutive pages. E.g. assume your page size is set to `10`. An `offset` of `10` requests the second page, an `offset` of `20` requests the third page and so on, provided there are sufficiently many items in your list.

You will use the parent account''s API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account''s ID (e.g., `on-behalf-of: account-id <account-id>`). When making a call on behalf of a Subuser, the property value should be the Subuser''s username (e.g., `on-behalf-of: <subuser-username>`). It is important to use the Base URL that corresponds to the region of the account or Subuser you specify in the `on-behalf-of` header. See [**On Behalf Of**](https://docs.sendgrid.com/api-reference/how-to-use-the-sendgrid-v3-api/on-behalf-of) for more information.'

    EmailPartialMatch:

      description: Specifies which records to return based on the records' associated email addresses. For example, `sales` returns records with email addresses that start with 'sales', such as `salesdepartment@example.com` or `sales@example.com`.  You can also use `%25` as a wildcard. For example, `%25market` returns records containing email addresses with the string 'market' anywhere in the email address, and `%25market%25tree` returns records containing email addresses with the string 'market' followed by the string 'tree'. Any reserved characters should be [percent-encoded](https://en.wikipedia.org/wiki/Percent-encoding#Reserved_characters), e.g., the `@` symbol should be encoded as `%40`.
