anyone or everyone

It is impossible to send something to everyone (meaning "everyone in the world" if said without a specific context.)

"anyone" here does not refer to everyone in the world but to "not the chosen few."    The invitations were sent out randomly.

You have received the invitation but you are not the chosen few.

Hi, Azz,

a. I got an invitation from their company and thought they really liked me. Then I found out that they send invitations to anyone.

b. The fact that you received samples of their chocolates doesn't mean anything. They send them to anyone.

I don't think 'anyone' can be replaced with 'everyone' in the above sentences. They send them more or less haphazardly, but they can't send them to everyone.

I think 'anyone' sounds a bit odd in these sentences, but actually the sentences are fine.

Am I correct?

Many thanks.

Yes, I see that 'anyone' sounds odd here, especially in 'a'. I think the best thing to do is to define 'one'.

a. I got an invitation from their company and thought they really liked me. Then I have found out that they send these invitations to any applicant, customer/ anyone they got their address or telephone number, etc.

b. The fact that you received samples of their chocolates doesn't mean anything. They send them to anyone of their clients.
