Targeted at online businesses aiming to refine their email marketing strategies, Liz explores whether using capital letters in subject lines can influence open rates and overall email effectiveness.

The Impact of Capital Letters in Subject Lines
Liz begins by addressing the common debate surrounding the use of capital letters in email subject lines. She posits that while her personal stance leans against the heavy use of capitals, the decision ultimately hinges on the individual’s brand personality.
Notable Quote:
"Should my subject line, should I use capital letters? I think the answer is no, but it is really, what is your personality?"
— Liz Wilcox [02:30]
Analyzing Spam Characteristics
To illustrate her point, Liz shares her Outlook inbox screen, highlighting the prevalence of spam emails that heavily use capital letters—a typographic style known as type case, where the first letter of each word is capitalized (e.g., "Buy One, Get One"). She contrasts these with legitimate emails to demonstrate how capitalization affects perception.
Key Observations:
- Spam Indicators: Spam emails often feature type case, long subject lines, typos, and poor preview texts.
- Legitimate Emails: In contrast, genuine emails like those from Liz's own list and Pete McPherson of ListGadget.com utilize either minimal capitalization or strategic capitalization to stand out.
Notable Quote:
"You know, the black river camper forms due May 1, City of Fort Walton Beach, paperless registration, recurring payment reminder. Then you see Liz Wilcox and you see Pete McPherson... it's super, super short."

Case Study: Liz Wilcox vs. Other Marketers
Liz showcases her own email subject lines, which predominantly use lowercase letters, such as "walking billboard." She contrasts this with competitors who use type case or include brackets, demonstrating how lowercased subject lines can stand out amidst a cluttered inbox.
Comparison Points:
- Lowercase Subject Lines: Easier to scan and differentiate from spam, enhancing visibility.
- Type Case Subject Lines: Blend into the spammy landscape, making them less noticeable.
- Brackets and Minimal Capitals: Effective when used sparingly, adding emphasis without overwhelming the reader.
Notable Quote:
"The only one that really stands out is Liz Wilcox's because there's no capital letters. So maybe if Carly had no capital letters, I would see hers faster. It's just the way the brain works."
— Liz Wilcox [14:20]
Encouraging Experimentation
While Liz advocates for minimal use of capital letters, she emphasizes the importance of aligning subject line styles with one’s brand personality. She encourages listeners to experiment with different capitalization techniques to determine what resonates best with their audience.
Recommendations:
- Align with Brand Personality: Whether it’s casual, formal, playful, or professional, the subject line style should reflect the brand's voice.
- A/B Testing: Conduct experiments to compare open rates between capitalized and non-capitalized subject lines.
- Monitor Results: Analyze the performance data to make informed decisions on subject line strategies.
Notable Quote:
"You just can't get over the lowercase thing. Go ahead. But do know that if you're willing to experiment, you might see some higher open rates."
— Liz Wilcox [16:50]
Practical Examples and Insights
Liz presents practical examples from her inbox to solidify her arguments. She points out how her own use of a single, lowercase word in subject lines outperforms more cluttered and capitalized alternatives from other senders like the United States Postal Service and Airbnb.
Examples Highlighted:
- Spam Emails: Often characterized by excessive type case and irrelevant content.
- Legitimate Emails: Short, concise, and strategically capitalized subject lines that attract attention without seeming spammy.
Notable Quote:
"That's why I don't use capital letters at all. But should you? I don't know, I would say experiment with it. Get... have some fun."
— Liz Wilcox [18:35]
