no, its a scam…delete.

It’s a scam, so don’t give them any information.

The only way it’s true is if you have a winning lottery ticket in your hand that you paid for.

But if you got an email, it’s not true. See link for official web site, and what they have to say about this kind of scam.

The UK lottery does not contact people by email. You have to buy a ticket at an official outlet then present that to claim your win.

It is scam. Yahoo (insert any company name here, this answer works for all!) do not run an email lottery, if they did you could guarantee it would be advertised all over their home page. Check out these links and search answers to see how many people ‘win’ the exact same lottery every day
…

Do not click on any links, the page you will be taken to will look authentic but is not
Do not send them a ‘courier fee’ or any other money
Do not hand over any bank details or passwords

Do report spam
Do delete

Remember there is no such thing as a free lunch. You cannot win a lottery if you haven ot bought a ticket. Anyone can set up an email account with Yahoo, they can use any combination of letters they choose. I could be ‘thequeenmother@yahoo.com’ or ‘disneyfreeticketsgenuine@yahoo.com’ That doesn’t mean that I am either of these and is fine as long as I don’t try to use the address to mislead people. Don’t be fooled by legitimate looking email addresses which end the same way as any other free account, don’t be fooled by fictitious titles such as ‘Dr’ or ‘Executive Director of Winner Claims’.

(I’ve answered this question so many times that I now keep this answer on my desktop and just copy and paste….that should give you a clue!)
