transaction | A transaction name for this step in quotes. To instruct VuGen not to create a transaction for this step, use an empty string, "".
RecipientTo | The name of the mail recipient(s) in the format: `"To=`email_address1`", "`email_address2`", . . .`

Subject | The subject of the mail in the following format: `"Subject=`my_subject`"`
From | An e–mail address representing the reverse path for the mail, that is, the sender. If this argument is not passed the From field is generated from the user name and server. "From=username@server"
ContentType charset | A content type in the following format: "ContentType=multipart/alternative". The default is `multipart/mixed` If the content type is `text/plain`, you can also specify the character set. The value must be quoted. Use the backslash to prevent the quote marks being interpreted as the end of the argument. If no character set is specified, the default is "`us–ascii`". For example: `"ContentType=`text/plain`",``"charset=`\"iso–8859–4\"`",`
MAILOPTIONS | The mail client configuration options and settings in the following format: `"MAILOPTIONS", "`Option1:value`", ."`Option2:value`" ,. .` For a partial list, see Mail Options.
- - MAILDATA | The mail data, provided as mail content, or as a file attachment. Mail content: This specifies plain text in the following format: `"MAILDATA", "`MessageText=...`", "`MessageBlob=...`" .` File attachment: `"MAILDATA"` can also specify a file attachment, in the form of a .dat file. The .dat file is specified using `AttachRawFile`. For example:"AttachRawFile= `mailnote1.dat`" The .dat file must include a header, followed by the message body text, or by base64-encoded content: Body text: For mail clients that support HTML format, you can include HTML tags and HTTP headers. Example of DAT file containing body text: Copy code
        Content-Type: text/plain; charset=us-ascii
        Content-Transfer-Encoding: 7bit

        Hello person1,
        Nice to talk to you

        Best regards,
        person2
  - Base64 encoded text: To include a PDF (or any binary file) as an attachment to the mail, the PDF must be encoded in base64, and the encoded content added to the .dat file. The .dat file header identifies the content as attachment, so that the API knows to send the content as a separate PDF file attachment. Example of DAT file containing binary file attachment encoded in base64: Copy code
        Content-Type: application/pdf;
        name="ExampleDocument.pdf"
        Content-transfer-encoding: base64
        Content-Disposition: attachment;
        filename=" ExampleDocument.pdf"
