Just e-mail it. If the person has an e-mail address, they will already have the ability to read e-mails and attachments or other accommodation that they need. That is not a concern on your end. You do not say the subject, but if someone does not even open the e-mail there is no consequence to the recipient. You are making a mountain out of a molehill. If a recipient gets it and asks for it in a different format - deal with it then.
