Direct Mail that performs like a growth channel

Two, on one platform. Addressed Direct Mail (ADM) posts to named households and businesses, built from your own customer file or B2B records. Unaddressed Direct Mail reaches every letterbox in the delivery districts you choose, delivered by Deutsche Post as Postwurfspezial, with no address list required. Both include planning, targeting, creative, printing, delivery, and performance tracking in Oppizi OS.

Unaddressed Direct Mail is advertising post delivered to every household or business in a selected area rather than to named recipients. In Germany it runs through Deutsche Post as Postwurfspezial: you choose the postcodes and delivery districts, and every letterbox in them receives your piece. Because no address data is bought or held, it has the lowest cost per letterbox of any mail format Oppizi runs and suits local offers, multi-location brands, and launches in a new city.

It depends on volume, format, how tight the targeting is, and how much of Germany you want covered. Unaddressed Direct Mail carries the lowest cost per letterbox because there is no address data to buy; addressed mail costs more and buys precision and personalisation. Our team quotes each campaign with printing and Deutsche Post delivery included, priced to compete with, and often beat, digital CAC.

Cold addressed mail averages a 1% response rate and unaddressed door drops 0.3%, per the JICMAIL Response Rate Tracker, measured across 4,939 UK campaigns. Response improves with AI-optimised creative, precise audience selection, and repeated exposure, all built into Oppizi OS.

Oppizi tracks direct mail ROI through promo codes, QR codes, unique URLs, and the conversion data you send back over SFTP or our API. The Oppizi OS dashboard shows real-time delivery, scan rates, and conversions, so you can calculate cost per acquisition and compare it against other channels. Test and control groups isolate incremental impact.

Choose Addressed Direct Mail when you have a list and want household-level personalisation. It is the strongest option for acquisition, retention, and win-back campaigns. Choose Unaddressed Direct Mail when you want full coverage of a postcode or delivery district without a list, for example a launch, a local offer, or a new city. Oppizi runs both in one platform, so campaigns can mix formats by market.

With Oppizi OS, campaigns can be set up in minutes. Unaddressed Direct Mail typically lands within one to two weeks of going to print. Addressed Direct Mail timelines vary with production volume and personalisation. Oppizi handles printing, fulfilment, and hand-over to Deutsche Post, so your team focuses on strategy while the platform manages logistics end to end.

Yes. Oppizi OS supports test and control methodologies, allowing teams to test different creative, offers, audiences, and areas simultaneously. Results are reported in a unified dashboard so you can identify what drives the best response and scale it, applying the same optimisation discipline to direct mail that digital teams apply to paid ads.

More than 33.2 million pieces have been distributed across Germany and nearly one million conversions tracked, all measured in real time in Oppizi OS through QR codes, unique URLs, and promo codes.
