Received an email from potential advisor and my name was wrong. should I correct him?

A few months back I contacted a potential advisor I an interested in doing my PhD with and he replied that he is considering my application and will be back in contact with me.

Today, I received another email from him basically saying:

Dear [My Correct Name],

Are you still interested in doing PhD with me? If so, I will interview you.

I wrote back that I am still interested and gave him my contact information.

He replied:

Dear [Completely wrong name/ probably another applicant],

Thanks. I will come back to you later.

Should I send an email correcting him or just forget it ??
