The SendMessage statement requires a recipient, subject, message text and a currently unused options parameter, in the format

SendMessage <recipient> <subject> <message text> <options>

• You cannot send a message to multiple recipients using this method - the statement would instead need to be called separately for each recipient
• Use \n in the message text so specify a line break
• Currently no <options> are defined, so leave that parameter blank

SendMessage "user@example.com" "Test message" "This is a test message\nThis is the second line\n\nThis is the fourth line" ""
