In case there is any doubt I can tell you that it’s most likely Royal Mail. Surprised? You shouldn’t be! Of course the mail may have the usual Royal Mail Postage Paid Impression (PPI) or it may have the PPI used by one of the downstream providers such as TNT or UKMail. In any case the PPI will
tell you who it was that picked up the mail and injected it into the Royal Mail system. What it won’t tell you is who actually put the letter through your letterbox and just so we’re clear on this; it’s very likely that it was the Royal Mail.
