RawMessage

The raw data of the message. This data needs to base64-encoded if you are accessing Amazon SES directly through the HTTPS interface. If you are accessing Amazon SES using an AWS SDK, the SDK takes care of the base 64-encoding for you. In all cases, the client must ensure that the message format complies with Internet email standards regarding email header fields, MIME types, and MIME encoding. The To:, CC:, and BCC: headers in the raw message can contain a group list. If you are using SendRawEmail with sending authorization, you can include X-headers in the raw message to specify the “Source,” “From,” and “Return-Path” addresses. For more information, see the documentation for SendRawEmail. Do not include these X-headers in the DKIM signature, because they are removed by Amazon SES before sending the email. For more information, go to the Amazon SES Developer Guide.
