Testing a campaign

Before sending a campaign to an entire list, you can send a test to a given email address.

// to a single email address
$campaign->sendTestMail('john@example.com');

// to multiple email addresses at once
$campaign->sendTestMail(['john@example.com', 'paul@example.com'])

In the sent mail the placeholders won’t be replaced. Rest assured that when you send the mail to your entire list, they will be replaced.
