Being offered  a free discount voucher from Amazon just to say "thank you" for being a loyal customer and they are asking you to click on a link to claim the freebie or to follow another link to be taken off the mailing list?

DELETE IT! It's a scam.

Remember

Amazon will never ask you for the following information in an email communication:

• Your National Insurance Number;
• Your bank account information, credit card number, PIN , or credit card security code (including "updates" to any of the above);
• Your mother's maiden name or other information to identify you (such as your place of birth or your favourite pet's name);
• Your Amazon.co.uk password.
