Every time you send one email to one recipient, it's deducted as one email credit from your plan. This occurs whether the email is ultimately deferred or sent to spam by the inbox provider.

It's important to keep in mind that emails sent using an Email API package are counted separately from emails that you send using a Marketing Campaigns package.
