Pick a city and a trade

How KnockPortal works

The hard part of direct mail is not sending a postcard — it is deciding where to send it. Building permits are public, and they show where work is already happening. KnockPortal turns that activity into an addressed list you can act on, and shows you the rule it used.

1. Look

   The whole city: every permit in the window, the blocks where work is clustering, and the houses on those blocks with no permit of their own. Free, no account.

2. Pick

   Blocks, buildings and addresses — your own choice, or a draft KnockPortal builds by a rule it shows you. You change it and approve it; nothing is assigned to you. Your pick is kept between visits.

3. Set up

   The postcard: logo, return address, contacts, text, licence number where the law asks for it. Addresses follow the postal rules. Quantity and cost are on screen.

4. Approve

   One screen holds the artwork, the addresses, the quantity and the full price. Nothing is printed before you approve it.

5. Send

   Printing and mail go out through a vendor, and the order keeps a status you can check.

6. Remember

   History stays on the address: when it was mailed, when it was walked, what you excluded. It feeds the next pick.

7. Repeat

   The map moves every day, the history adds up, and the subscription buys the cycle rather than access to the data.

The same pick has a second output: a list and a walking route for a door-knocking crew.

What is free and what you pay for

• Looking, picking and building a mailing are free, and none of it needs an account.
• A subscription covers acting on it: sending the mailing and taking the addressed list out. You are asked to subscribe at the moment you send — not before.
• One subscription covers one city and one trade.
