sendy Utility version $local::bin::sendy::VERSION - for Sendy 6.1.2+, bundled with Webservice::Sendy::API (https://metacpan.org)

This utility is distributed with the Perl library, Webservice::Sendy::API. It uses
the library to implement the following subcommands. It is a good example of how
to use the Perl module directly, since this utility and the module are maintained
together.

Subcommands:

  count        - list count   
  create       - create campaign; draft, send now, or schedule send
  brands       - list brands
  delete       - delete email address from list
  lists        - list lists in a given brand Id 
  subscribe    - subscribe email address given a list Id
  status       - get status of an email address, given a list Id
  unsubscribe  - unsubscribe email address given a list Id 
  help         - print this help 
  "-h"         - print this help
  "-v"         - print version banner of this utility, then exit

This seems like something that my long lost brother, Grant, may see; and
if he does I hope he knows I love him.
