ResourceFunction["SendMailFromNotebook"][] creates a new notebook for composing an email with a send button.
Before sending mail, ResourceFunction["SendMailFromNotebook"] returns an interface that previews mail messages, then gives the option to send or cancel.
Within the mail notebook, the section cell can contain multiple email addresses separated by commas or newline characters.
Subject lines can be given as subsection or subsubsection cells.
The body of messages can consist of multiple text cells.
Explicit
"From" and
"FullName" elements should be given in
assoc if these are to be included in mail messages. Otherwise, the default behavior of
SendMail for the current account will be used.
Attachments can be inserted after the text cells for the body of the message. Attachments can be made by pasting an
ExpressionCell or by dragging and dropping a file into the template notebook.
