KnockPortal at a glance

KnockPortal helps contractors decide where to send direct mail. It uses public permit records for your trade to show where recent permitted work is concentrated, filters out homes with prior permits for the same kind of work, and builds postcard mailings to nearby homes based on the areas you choose. Autopilot is the main way to use KnockPortal: you set a mailing rule and a spending cap per run, then authorize automatic sending under those settings. Sending depends on the required checks and payment, and you can pause or stop the rule. You can also build, approve and pay for a one-off mailing yourself. It shows where permit activity is happening; it does not predict who will hire you.

Available in San Francisco · Solar: Autopilot (Neighbors of new permits) and one-off mailings.

San Francisco · Solar snapshot: Nov 14, 2026, 16:14 UTC. It covers the last 30 days of permits: 63 permits at 62 houses.

Subscription for San Francisco · Solar: $99.00 a month. Postcards: $0.89 each, printing and postage included.

One job covers a month of the subscription and 100 postcards if at least $188.00 is left from it after the job's direct costs, such as materials and crew. This is arithmetic, not a forecast.

Postcards are 4.25 × 6 inches, printed in full color on both sides.

Permit records show where permitted work is concentrated, not where work is under way or which homes need it. A home with no permit on record may still have had the work done.
