No where else is it more important to inspire curiosity than in your subject lines. If people aren’t curious, they won’t open the email, read your message and click your link. It all begins with creating curiosity in those very few words they see in their inbox.
Here are a few subject line formulas to get you started.
Simply replace the words in brackets with your own words.
For example,
- Kindly don’t [open this mail]
Could become…
- Kindly don’t go to bed tonight, do this instead
- Kindly don’t join unless you have what it takes
- Kindly don’t run naked through the streets (I’d open that one!)
Here are the subject line formulas:

Don’t Open [This Email]*
*Note about this last one: I know it’s a popular one to use because it works. But for whatever reason, I NEVER open an email that says not to open it.
I guess it’s because I know what the writer is doing, and I refuse to fall for it. However, if the email writer said something like, “Don’t Open Your Sock Drawer,” then I would totally open that email to see why not.
Okay, that got you started with curiosity subject lines. Now let’s work on headline formulas for inspiring curiosity and getting your content read. Please be sure to test to see what work best for you.
