Week 2: Subject Lines and the Open Decision
Subject lines as the pitch, not the label.
15 February 2027
Week 1 established that a cold email has to give the reader enough to decide with. This lecture argues that decision usually gets made before the body is ever opened, at the subject line, and that most writers treat the subject line as a label on the pitch rather than as the pitch itself.
Before the lecture
This is just to get a quick understanding before the lecture. The examples and the rest are in the lecture, so it’s advisable you attend.
In brief#
This week’s failure is the subject line that describes the email instead of stating the fact inside it. “Following up” makes the reader open the message to find out what it’s about; “Grant deadline moved to Friday” lets them decide without opening anything. That gap matters because most subject lines fail this test while their writers believe they’re being appropriately restrained rather than costing the reader a wasted decision.
Outline#
- the open-or-skip decision happens before the body is read
- descriptive vs. self-sufficient subject lines, and what “self-sufficient” actually requires: relevance and urgency decidable without opening
- why unresolved ambiguity forces the open a subject line should prevent
- worked example: a “Following up” that answers nothing, rewritten to answer all three
- what published data on “Quick question”-style subject lines shows about how common this is
