Currently documentation and examples include the line:
$sg->client->suppression()->spam_report()->_($email)->...
This is an incorrect end path, returning status code 404. The correct path should be:
$sg->client->suppression()->spam_reports()->...
(with an "s" on the end of "spam report")
Thanks @jverlee!
I've added this to our backlog for a fix.
