Why do you have a mailbox with a UK street address? Perhaps you use expatpost because you don't want anyone to know where you live or work, or that you have relocated abroad. So, do you really want to reply to letters, or return that official form, with a foreign stamp on the envelope. . . or an incorrect postmark?
Outpost is a unique service for British expats that is available to both Private and Business mailbox customers. Use outpost and your letters or parcels will be delivered, by the Royal Mail, with a postmark that matches your mailbox address!
