Preview, copy, or send the monthly performance email to each premium advertiser.
Heads up: sending uses PHP's built-in mail(). Many hosts require SMTP
(e.g. via your host's mail service or a service like Postmark) for reliable delivery — if Send fails
or emails land in spam, that's the fix. Preview and Copy HTML always work regardless, so you can paste
into Outlook and send from your normal address in the meantime.
