Hushmail Offers

Hushmail is a straightforward email service that offers automatic end-to-end encryption through OpenPGP. Furthermore, it adds some extra security layers by enabling users to use two-factor authentication and by scanning all emails for viruses. Unfortunately, it only offers one billing cycle, i.e. annual payments. Nevertheless, it costs only $4.17 per month, and you can get it for an even lower price lower by adding a coupon code when entering your payment details.
