Nuts.com counts the deadline down in the subject line
20% Off Your Own Trail Mix Ends Tomorrow
20% Off Your Own Trail Mix Ends Today!
Step by step
- 1
Two sends 24 hours apart with the same offer; only the deadline wording changes, from "Ends Tomorrow" to "Ends Today".
- 2
The offer leads and the deadline trails, so the subject still reads as a deal if it's cut off on mobile.
- 3
The body headline is "Build your own custom trail mix", with "20% off + free shipping".
The psychology
Why it nudges
Nuts.com uses a deadline: a specific, near cut-off gives people a reason to decide now instead of later. The "ends" wording also frames the last day as losing the 20%, a loss framing. Whether the second send earned more than a single email is not public.

Context
A DTC food retailer emailing its existing list. The custom trail mix is likely a higher-value product it wants to push. Sending twice in the last 48 hours is a common end-of-promotion pattern.
Honest nudge or dark pattern?
Conditional
Honest nudge if the deadline is real and the offer doesn't come straight back. Deadlines that repeat or reset are fake urgency. See deceptive.design/fake-urgency.
Steal this, honestly
- Plan the final 48 hours of any real promotion as two sends: "ends tomorrow", then "ends today". Change only the deadline words.
- Put the benefit first and the deadline last in the subject line.
- Exclude anyone who bought from the first send.
What to test: One last-day email vs the two-step countdown. Measure revenue per recipient and unsubscribe rate.
