The company is sending 1,000 customers a mailing in a silver envelope featuring sliding tabs; when pulled, they reveal statistics about Special Delivery's major competitors, which include TNT, Citilink and Securicor.
The campaign was created by Claydon Heeley Jones Mason, which conducted research into Royal Mail customers' usage and opinions of Special Delivery compared with rivals.
Royal Mail claims that NOP survey findings showed that it consistently outperforms its rivals. The statistics, collected in October, demonstrated Royal Mail's 98% on-time delivery rate.
