UK Mail, one of the largest express delivery companies in the UK, already has a depot in the Livingston area of West Lothian. But the new sort centre is the first integrated Scottish-based print and mail facility and involved an investment of £250,000, the company said.

Imail, launched in 2008 as a rival to Royal Mail's first class service, allows users to email documents that are then printed and sent for next day delivery.

The new Livingston set up includes two Konica Minolta C8000 printers to print letters and marketing postcards and has led to four new jobs with plans for more investment and jobs next year.

Imail general manager Andy Barber said: "From a standing start in late 2008 imail now prints and mails more than 20m client letters and postcards annually. Now we can now grow further. We expect to invest a further £500,000 in the next year and double staff numbers."

Imail allows organisations to send letters, direct mail, marketing cards and other forms of correspondence from their PC, Mac or Laptop. Printing, production and postage of letters aims to offer clear and simple payment for customers to increase cost and efficiency savings.

UK Mail Group is one of the largest independent parcels, mail and logistics services companies in the UK, with a national network of 55 sites and 3,000 drivers. It is accountable for over 17% of all addressed mail within the UK.

The group recently announced a 6% year-on-year increase in revenues for Q1 2013. The parcels’ business saw strong performance, with daily volumes for the quarter increasing 25% compared to the same period last year.
