Hey, hey! Liz Wilcox here, and you’re hanging at the virtual watercooler for another episode of The Email Sound Booth—specifically, the only podcast episode where we deep-dive into whether using capital letters in your subject lines is a yay or nay. (Spoiler: I have opinions, and they’re backed by a little something called “Liz’s personal inbox.”)

If you’re a regular around here, first of all—thank you! (And show your girl some love with a review, even if you think I ramble more than a group chat after midnight.)

Episode TL;DR:

This episode is for all you biz besties who want their emails to pop in the inbox—without looking like a shouty spam bot or, worse, slipping into the graveyard of unopened messages. I fire up my own Outlook (messy, mildly embarrassing, hopefully relatable), and walk you through exactly what kind of subject lines get my attention…and which ones scream “delete me please.”

Let’s Break It Down:

• Capital Letters or Nah?

  I’m Team Lowercase. In my inbox, all those capitalized, “Title Case” subject lines blend right into the sea of spam and autofiltered nonsense. But a simple, lowercase subject? It jumps out. Just one word, no caps—boom, instantly visible.

• But Don’t Take My Word For It—Experiment!

  If you love your capital letters (maybe you were the kid who aced handwriting practice), go for it! Make it YOU. But if you’re itching to get a few more opens, try swapping to lowercase—just for a hot minute. Your people might surprise you.

• Proof from My Inbox:

  Spam = usually “type case” (that’s every first letter capitalized). Real, interesting humans? Lots more lowercase happening—and it stands out.

• Honest Biz Chat:

  This isn’t about some rigid “only lowercase emails convert” rule. It’s about zigging when everyone else zags, finding what fits your vibe, and being bold enough to test something new.

Quick Win Actions for Your Next Send:

1. Try writing a single-word, all lowercase subject line.
2. Review your inbox—what stands out to you?
3. Don’t be afraid to mix it up and see what happens!

You’re the best. If you learned something new, drop me a line or leave a review. And remember: you don’t need to yell (with caps) to get noticed—sometimes the quietest emails get the most love.

Catch you next time!
