Thank you survey

The Thank you survey is an ARG-esque hidden query puzzle that is part of the Spamton Sweepstakes event. It is one of the silence links that was added on May 8, 2025, which teases hidden content for Chapters 3, 4, and 5 for Deltarune.

Participation rules

Readers are tasked with answering the page's question, which appears as page's tab title. The page itself contains two entry fields: the top-most expects the reader's email, the middle for an answer, and the bottom is a button to submit. Submitted answers are sent to a remote server, and the page displays, "Thank you." immediately after. Only the reader's recent-most answer would be submitted and responded to.

Pressing the button and not filling sections causes slightly different responses from the site: "Unknown contact." occurs if the reader did not put an email, and "She never smiled?" occurred if the reader did not input an answer.

Response emails occurred if the reader was already signed up to the official Undertale/Deltarune newsletter prior to this event, and readers continued to receive emails unless either: the reader did not reply, or had responded a certain way in a previous round. Response emails also have the bottom text as, "You are getting this email because you 　　　　　 for the 　　　　　　　 Mailing List."

History

Round 1

On May 8, 2025, the /chapter4/thankyou/ URL was indirectly hinted at via /chapter4/message/.

The first field expected an email, the second field expected any content.

On May 9, 2025, the page was updated and the entry fields were removed. It only displayed the text, "Thank you."

Later, a (no subject) "Promotions" email was sent to users that had input their email in the first field, and are also already subscribed to the Undertale/Deltarune Newsletter.

If the second field had a number or time interval entered, the message varies, but starts with "You answered" with a listed number, then the word "seconds/minutes/days/years" depending on the inputted response. If anything else was entered, the message is blank.

Any email that put in an answer received a response, and, regardless of the contents of the response, moved on to Round 2.

"How long did it take for her to smile?"

Responses	Submissions
	Any non-number or non-time submission.
You answered [value] minutes/seconds/days.	Any number or time submission. Inputting a number without a timestamp defaulted to seconds.

Round 2

One of the many responses to answers submitted in Round 2

On December 19, 2025, a new email was sent out to people who had previously input their email on May 8. The email is titled, "Another chance." and links to the page, where text could once again be inputted. The page changed again to only state "Thank you." on December 20, 2025.

On December 21, 2025, an email was sent to returning recipients, which varied based on their submission.

All emails, apart from blank ones, start with "You answered [submission]." "Until next time." email titles also end with "Move forward with this answer." in the main body. As described, the reader emails with the latter title would get an email for the next round. Certain times and years had prompted "move forward with this answer": Negative times, 0-24 hours and 5 through 16 plus years.

Round 3

On June 9, 2026, the next email was sent after the DELTARUNE Chapter 5 Release Date Announcement newsletter, though it was only sent to round 2 readers that had "Until next time." as an email title. Both the subject and main body listed, "What about next time?", with it linking to /chapter4/thankyou/. Unlike the previous rounds, the query was changed.

The replies were ongoing until the latter half of June 10, and it was open for longer than 24 hours before closing on June 11, 2026. Afterwards, the page's title was updated to, "INTERIM RESULT", and lists the following on the page:

• Available entrants: 1,571
• Total received: 1,229
• Next correspondence: When less than 24 hours are left.

"Where will it take place?"
