iTunes has a tendency to keep on sending you emails even if you unsubscribe. It still takes up to 5 days to unsubscribe even IF you used the proper site to do so. In the meantime, you're stuck with the spam and whatever other emails you were sent.
It's also doing your Gmail inbox no favors while receiving iTunes gift cards that you might not be able to use or plain didn't want anyway. Basically, you could end up with a large mess from all over the place needlessly cluttering your Gmail account.
- Install Block Sender for Gmail by clicking the "Install" button found in the upper right-hand corner of this site. The installation won't take long. Open Gmail when it is done.
- After signing up for a Block Sender account and linking your Gmail account to Block Sender, open the unwanted email from iTunes, and click the "Block" button on the messages toolbar.
- Select the "Emails with same subject" option.
