     * The raw email message. The message has to meet the following criteria:
     *
     * - The message has to contain a header and a body, separated by one blank line.
     * - All of the required header fields must be present in the message.
     * - Each part of a multipart MIME message must be formatted properly.
     * - Attachments must be in a file format that the Amazon SES supports.
     * - The raw data of the message needs to base64-encoded if you are accessing Amazon SES directly through the HTTPS
     *   interface. If you are accessing Amazon SES using an Amazon Web Services SDK, the SDK takes care of the base
     *   64-encoding for you.
     * - If any of the MIME parts in your message contain content that is outside of the 7-bit ASCII character range, you
     *   should encode that content to ensure that recipients' email clients render the message properly.
     * - The length of any single line of text in the message can't exceed 1,000 characters. This restriction is defined in
     *   RFC 5321 [^1].
     *
