mail truffa

Ho ricevuto questa mail con una registrazione ad un sito mai effettuata:
"Congratulations, you are all set!
Hello [email protected],
Registration completed
Thank you for joining us!

Ovviamente io non sino entrata nel sito ma leggo che:
" Akira Marketing Europe B.V. provides unlimited access to brain enhancement website talentbrainportal.com. Normally on Sign up a Subscriber will receive a 3 day trial period for 1 EUR. If the user doesn’t actively stop their subscription within 3 days they will be billed 55 EUR on the 4th day and this 55 EUR charge reoccurs every 30 days until the Subscriber actively stops the service. The member is responsible for such fees according to the terms of the Site. Once a member has the ability to access the Website using the E-ticket assigned to the member, subscription fees become non-refundable.

Non essendo mai entrata nel sito mi devo preoccupare?
Grazie
