Printing and delivering flyers can be time-consuming and costly. Also, it is illegal for the general public to put flyers into US mailboxes. The USPS has a service to help. Every Door Direct Mail® costs 14.5 per piece and does not require a postage permit. How does it work? You pick the neighborhoods you want to reach, and a Postal Service Letter Carrier takes your printed flyers to every home while delivering the day’s mail. Your lost dog flyer gets directly into the hands of the homeowner.
Ask your local postmaster for details. Some printing requirements apply.
