CAMBRIDGE, MA — A landmark study from the Institute for Inbox Degrowth has confirmed what the entirety of the working world has quietly suspected since approximately 2011, finding that 97% of all emails beginning with the phrase "just circling back" contained no actionable information, advanced no professional relationship, and could have been permanently unsent without measurable consequence to any known business outcome.

The study, which analyzed over 4.2 million follow-up emails collected across seventeen industries over a six-year period, found that the remaining 3% of "circling back" emails were sent by accident to the wrong recipient and therefore also did not need sending.

"We expected the number to be high," said Dr. Fenella Croup, the institute's Director of Longitudinal Correspondence Futility and lead author of the study. "We did not expect it to be this high. Or, honestly, this clarifying for us as individuals who also receive email."

"In several documented cases, both the sender and the recipient had completely forgotten what the original email was about. The circle, in other words, had closed around nothing."

The findings introduce a new unit of measurement — the "Cloop," defined as one complete send-and-ignore cycle initiated by a circling-back email — and estimate that American workers collectively generate 1.8 billion Cloops per business day, consuming an estimated 14,000 megawatt-hours of server energy to store messages that convey, in their entirety, the information that someone continues to exist and owns a keyboard.

Researchers were careful to distinguish "circling back" emails from related subspecies including "just wanted to resurface this," "bumping this to the top of your inbox," and "following up on my follow-up," all of which are currently under separate investigation and expected to perform similarly.

The corporate communications industry has pushed back on the study's conclusions. Garrison Fletch, Senior Vice President of Stakeholder Velocity at the consultancy Momentum Praxis Group, called the research "reductive" and "exactly the kind of thinking that gets siloed."

"Circling back is not about information transfer," Fletch said in a statement. "It's about signaling presence, demonstrating initiative, and maintaining the perception of forward motion in the absence of any actual forward motion. That has enormous value. Measurably enormous. We have a deck on it."

The Institute for Inbox Degrowth, which has operated since 2019 out of a shared office suite above a Cambridge dry-cleaner, is now calling on major email providers to implement what it terms a "Necessity Delay" — a mandatory 72-hour hold on any outgoing message containing the phrase "circling back" — during which the sender would be prompted with a single question: "Are you sure?"

Early modeling suggests the feature would reduce global email volume by 11%, lower workplace anxiety by a statistically significant margin, and cause no disruption whatsoever to any project currently in flight.

The study will be published next month in the Journal of Applied Organizational Quietude, assuming the peer reviewers respond to the reminder email.
