Register & Verify
Create your free account and enter your home address. We send a physical postcard with a 6-character verification code via USPS — confirming you actually live there.

AI Reads Your Mail
Every offer is automatically categorised, translated into your language, and analysed by AI — rates, terms, deadlines, and promo codes extracted in plain English. High-priority items surface first.
03
Compare, Shop & Save
Ask the AI to find a better competing deal or get live insurance quotes without leaving your inbox. Track price drops on your watchlist and get push alerts when rates hit your target.
01
Create & Fund Account
Register your business — credit card company, auto dealer, insurer, real estate agency, or home-services brand — choose a plan and load credits. Delivery starts at $0.03 per household.
02
Build & Target
Design rich messages in the WYSIWYG editor — embed images, video, and audio. Target verified households by ZIP, county, state, or country. See a live reach count before spending a single credit.

Send, Schedule & Track
Launch immediately, schedule for a future date, or save as draft. Track open rates, click rates, cost-per-send, and geographic breakdown — down to ZIP level — in the campaign detail view.
Why DMB

Built different,
for good reason

Structural advantages that no physical mailbox or email inbox can match.

🔒
~0
phishing risk
Near-Zero Fraud & Phishing Risk
Physical mail and email are the top vectors for identity theft. DMB only accepts campaigns from verified, approved businesses — no spoofed senders, no fake offers, no credential-harvesting links ever reach your inbox.
🌱

ESG Tailwind — Zero Carbon Delivery
Every digital send eliminates one physical mailpiece — no paper printed, no trucks dispatched. As campaigns scale from thousands to millions, the carbon offset compounds. DMB is the only direct mail channel with a net-zero delivery footprint.
📮

forever
Address Portability — DMB ID Follows You
Move across the country and your digital mail comes with you. Unlike physical mail that requires address updates with every sender, your permanent DMB ID means businesses always reach the right person — not just the current address.
