Where does the homeowner data come from?
We pull from public property records, updated daily. When a home sale closes in your zip codes, it appears in your dashboard.
How do postcard campaigns work?
Select properties from your dashboard, choose a design, customize your message, and we handle the rest - printing, addressing, and mailing via USPS First Class.
What's included in the free trial?
7 days of full access on the Starter plan - track up to 10 zip codes, view homeowner leads, export CSVs, and set up postcard campaigns. No credit card required.
How much do postcards cost?
Starting at $0.75 per card depending on your plan, printed and mailed. No minimum order. You only pay when you launch a campaign.
Can I export leads to my CRM?
Yes. Download a CSV from your dashboard at any time, or use webhook notifications to push new leads directly into your tools.
How do agents work?
Agents put your postcard outreach on autopilot. Set filters (zip codes, home value, square footage, recency), pick a design, and set a monthly budget. Each day, your agent sends a postcard to every new homeowner that matches - until it hits your budget cap for the month. Pause, edit, or delete anytime.
When is the best time to reach a new homeowner?
The first 30-90 days after move-in is the highest-intent window in local services - new homeowners make more vendor decisions in this period than in the next several years combined. FirstKnock gets you there within days of closing.
Can I cancel anytime?
Yes - no contracts or long-term commitments. Cancel from your account settings whenever you want.
Launch an agent to put postcards on autopilot, or send one-shot campaigns - new homeowners appear in your dashboard within days of closing.
