Send from a verified sender on one of your domains.

index.php

use MailCraft\MailCraft;

$mailcraft = new MailCraft(getenv('MAILCRAFT_API_KEY'));

$mailcraft->emails->send(
    from: '[email protected]',
    to: ['[email protected]'],
    subject: 'Welcome!',
    html: '<p>Thanks for signing up.</p>',
);

Keep your API key in the MAILCRAFT_API_KEY environment variable, never in source control. Create one under Settings → API keys, scoped to just what this app needs.
