These email gateway's have been developed to facilitate email to bitmessage transmission :
Bitmessage Email Gateway is a free service that gives you a bitmessage username with a bitmessage.ch domain to send and receive messages with normal (unencrypted plain text email) email addresses. Messages can be sent to bitmessage usernames from your email which remain encrypted and anonymous.
bitmsg.cc allows you to send an email to any bitmessage address by simply adding @bitmsg.cc to the end of the bitmessage address .
