Dear Royal Mail,
I see that as well as the expected yearly increase in postage cost, you have also changed the conditions of international mailings. ‘Airmail’ is now called International ‘Standard’ and surface mail has become ‘Economy’. The measurements now match the sizes for mailing in the UK.
My question to you is how do you send something that is only 24×16.5×0.5cm that is close to 100g? What would you send that heavy, that thin? Sheet gold?!
Unfortunately for us casual international mail users, who send letters abroad for pleasure, it means it’s cheaper to send two envelopes if there’s a risk of the envelope being over 0.5cm thick.
