If you’ve ever received a letter from Nielsen with real cash inside, you’re not alone — and it’s not a mistake.
Across the U.S., Nielsen has been sending out cash-in-the-mail survey invitations to selected households as part of their research programs. Unlike most survey companies that pay in points or gift cards, Nielsen still uses physical cash to encourage participation.
Here’s how it works — and how you can check if your household qualifies.
It Usually Starts With $1… But That’s Just the Beginning
Many Nielsen letters arrive with $1 cash included. This isn’t the full payment — it’s a small incentive to open the letter and answer a few questions.
Once completed, Nielsen may follow up with additional payments, often:
- $5 per person, or
- $10 per person in the household
The key detail most people miss?
👉 Each eligible person in the household can be counted.
That means larger households often earn more.
Example:
A 4-person household could earn $20–$40 from a single survey invitation.

December Bonus: $20 Sent via PayPal (Limited-Time)
In addition to mailed cash surveys, Nielsen is currently offering a December bonus where new participants can receive $20 sent via PayPal after opening an account and completing initial registration.
This bonus is separate from mailed surveys, meaning some users may receive:
- Cash in the mail and
- Digital payments via PayPal
Availability varies by household profile and location. Not all users receive the same offers.
