How can i know if real emails from apple?

Many scam emails have the same tell-tale signs. This one has at least a few.

1. Apple addresses you by name, not Customer.

2. The grammar is horrible.

3. Apple does not use attachments of any kind in their iTunes or App Store email receipts.

You’re welcome. Unfortunately, such emails are almost impossible to stop. The important thing to remember, is never respond to the emails, click on any links in such emails, or use the “unsubscribe“ button in the emails.

It is a phishing attempt. Do not respond to, or otherwise act on the email.
