QR Codes and Campaign Tracking
QR codes in Open Letter Connect make it easy to track engagement from your direct mail. Each QR code is unique for every contact, so when a recipient scans it, you’ll know exactly who responded.
You can use these scans to:
Track who interacted with your mail piece.
Send that data back to your CRM through a webhook for real-time notifications.
Measure how many people scanned your mail versus how many received it.
How QR Codes Work
When you add a QR code to your mailer, Open Letter Connect automatically creates a unique tracking link for each contact on your list.
That means:
No two QR codes are the same.
Each scan can be traced back to a specific contact record.
You can see engagement activity inside your CRM when connected via webhook.
Adding a QR Code
In the Template Builder, click QR from the left-hand menu.
Click Add new QR code.
Enter your destination URL in QR URL (this is where the user will land when scanning the code).
Complete the optional UTM parameters for better analytics:
UTM Source: Example, direct mail
UTM Medium: Example, QR Code
UTM Campaign Name: Use this to group scans by campaign name, such as Spring Mailer or Investor Outreach.
Use Custom UTM 1–3 for any extra tracking values your CRM or analytics system uses.
Once complete, position the QR code anywhere on your mailer layout.
Where to add images:
Screenshot of the QR code setup panel (the one you uploaded).

Using QR Codes with Your CRM
If you want to track scans in real time, connect your QR codes with your CRM via webhook.
When a contact scans their code:
Open Letter Connect logs the event.
The webhook sends the contact details and scan time back to your CRM.
You can use that data to trigger actions like follow-up emails, calls, or text messages.
(Example: When John Doe scans his postcard, GHL updates his record and triggers a “Call Lead” task.)

Best Practices
Use UTMs: They help you understand where your traffic comes from and what campaign performed best.
Keep URLs short: Use redirect or tracking links instead of long URLs.
Place QR codes where they’re easy to scan: Bottom right or centered is often best.
Test first: Send yourself a test mailer and scan the QR code to make sure it directs properly.
