I have substituted more than 2/3 of the private traditional postal mail with e-messages. (Almost all the messages I used to send by traditional postal mail I now send with e-messages).
Več kot 2/3 navadne pošte sem nadomestil/a z e-pošto. (Skoraj vsa sporočila, ki sem jih prej pošiljal/a z navadno pošto, sedaj pošiljam z e-pošto).
