为什么mandrill send_at与php正在立即发送

Question

I have a script that prepares an email and then schedules it to send 24 hours later... I call the Mandrill API

$mandrill->messages->sendTemplate($template_name, $template_content, $message, (string)$send_at);

and the send_at value is 2016-09-15 09:09:28 or whatever in the future.

The email triggers right away though!! How do I get it to send 24 hours in the future.

Answer 1

Are you using a UTC timestamp? Have proper credit on file to use this feature?

Send at documentation from https://mandrillapp.com/api/docs/messages.php.html: when this message should be sent as a UTC timestamp in YYYY-MM-DD HH:MM:SS format. If you specify a time in the past, the message will be sent immediately. An additional fee applies for scheduled email, and this feature is only available to accounts with a positive balance.
