In addition to attachments and links, body payloads provide a great opportunity to test mail gateway protections against threats like brand impersonation and business email compromise attempts.
Body payloads have a range of built-in variables that are populated at send time. These are denoted by the syntax, #{}, and can be leveraged in your own custom payloads. Populating a body payload with the recipient’s email address, for example, could be achieved with a #{RECIPIENT_EMAIL} placeholder.
NOTE: Variable substitution is currently only performed for body payloads, not to attachments and links.
