Subject lines have a huge impact on marketing success. Yet, what busy marketer has the time to really focus on the cognitive psychology behind a 75-character subject line?
In this Web clinic, Flint McGlaughlin, Managing Director, MECLABS, will share what an analysis of more than 100 successful subject lines reveal about how people choose to open an email. You will learn the common traits of the most successful email subject line as well as the most common mistakes.
Specifically, we will address the following common questions related to subject lines:
• What makes a subject line engaging?
• What factors make a subject line more likely to be deleted?
• How do we express value through so few characters?
• How long/short should subject lines be?

21. Computer Logic vs. Customer Logic
• A computer draws conclusions
from algorithms, rules, switches
and settings.
• A human draws conclusions
from context, emotions and
desires.
22. What We Discovered
F
Key Principles
•
Customers aren’t trying to open your emails, they are trying to eliminate
them.
•
To prevent elimination, the marketer must ensure an immediate
connection with the customer.
23. Today’s Focus
Today, we are going to review two effective
approaches to build an immediate connection
through your subject lines.
25. Connect to an Internal Issue
F
Key Principles
•
An interruption is not enough; we must transfer customer attention into
customer interest. This transfer occurs when we create a space in the
customer’s mind that can only be filled with what is coming next.
•
In most cases, we can create this space by connecting to an internal issue
common to our customers, and intensifying the offer’s connection to that
issue to attract them towards a potential resolution.
26. Example: Internal Issue
Protocol ID: CS7771
Sent to: Previous (non-active) customer list
From This
[Company Name]: A New Way to
Order
While this hints at potential issues in
their ordering, it does not make a clear
connection
27. Example: Internal Issue
Protocol ID: CS7771
Sent to: Previous (non-active) customer list
From This
[Company Name]: A New Way to
Order
To This
[Company Name]: Now only 2-meal
minimum order
This clearly connects the offer to an
internal issue experienced by the
customer (minimum required cost)

28. Connect to an Internal Issue
Internal Issue Examples:
• Limited resources (time, money, help)
• Unmet expectations (work and family)
• Deficient skillsets (inability or inadequacy)
• Operational difficulties (routine usability)
• Fragmented perspectives (ignorance or misunderstanding)

Messages have more meaning when they are presented in a
story – i.e., a series of events that build toward a conclusion.
When you connect your message to the customer’s external
story, it will have more meaning.
37. Connect to an External Event
External Event Examples:
(recent or distant)
• An action or behavior
• A conversation
• A single exchange (completed or abandoned)
• A cancellation (membership, contract, recurring transactions)
• A service interaction
