Is the above message from Stellar?
This is a SCAM. They are using a phishing domain where the 's' from stellar.org is replaced by 'ś' if you pay close attention.
Also the e-mail has a random FROM address. Unfortunately I also received it, three times. Somehow an e-mail database must have leaked.
Be careful, do not fall for it! No legitimate campaign will ask you for private keys or any upfront deposit.
