Could a single word really increase your open rates? Liz Wilcox — the Fresh Princess of Email Marketing — says yes! In this short and fun episode, Liz shares her favorite subject line hack: the one-word subject line. Learn why it works, how to come up with the right word, and see real examples that have boosted her engagement and replies — all while keeping email writing fun again.
How Liz discovered the power of one-word subject lines (inspired by Kennedy from Email Marketing Heroes).
Why one-word subject lines visually stand out in inboxes — especially on mobile.
The simple test: write your email, then pick one word that captures the essence or emotion of it.
Real examples that grabbed attention and boosted open rates:
"Debate" — sent the day after a presidential debate, but really about naming The Email Sound Booth.
"Patricia" — sparked intrigue about Liz's sister and business manager.
"Nudge" — replaced "Don't forget to put this on your calendar" and performed way better.
"Pressure" — kicked off the new year with a message about releasing expectations and building slowly.
How one-word subject lines increase curiosity, make your emails stand out, and even spark replies.
A challenge from Liz: try this trick in your next email and share your results in The Email Sound Booth Facebook group.
Keep it simple: One word can stand out more than a long or overcomplicated subject line.
Go for curiosity: Use words that hint at your topic but don't give it away.
Visual variety matters: A short subject line literally looks different — and that helps your open rate.
Make it meaningful: Choose a word that captures the tone or feeling of your email.
Experiment and track: Every list is different — test it and see what happens!
