No, not with public-key cryptography¹, which is what is usually used.
You need the recipients public key to be able to encrypt the email to
them.
If you and the recipient share a secret (eg. a password), you could use
symmetric encryption², but you have to share the secret in some other
way first, so it's rarely a solution.
