i also recieved this email
To me its putted the same person
of course its a scam
but
because this sentence : "After you make a transaction in the amount of 0.0025 BTC, click the button below to CHECK the TRANSACTION STATUS, as soon as our system registers the sending of BTC from your address, you will receive the amount donated to you in full."
i think the sentence means its 0-conf
so when mempool will be more full i will check it with double spend
because of course they are scammers, but many scam in the start pay to make more people come and then not pay anybody, so maybe they in the start and in the start maybe they pay, but in the future 100% they will not pay anybody
