An attachment in Connoisseur has more impact than a loose attachment in the mailbox. And it costs only marginally more than going with your own direct mail. The advantage of an appendix is that you set the level of the number of pages, the choice of graphic quality and the size.

An attachment sent through the Connoisseur is observed by virtually 100% of recipients compared to the many times worse outcome of sending the attachment directly through the post to a household.
