As you should be aware, a new Mailmark service was introduced this year on 31st March 2014 by Royal Mail. With it came Mailmark Prices which were released with all of the other Postage rates for 2014.
The new franking system has gained a lot of interest from many customers in the UK, and Mailmark is proving to be a big success. The Mailmark service brought with it lower franking prices, and this is one reason for why it is becoming so popular.
