5. If you want to increase your email open rate
You need to write better subject lines

6. Use these seven tips to
Write killer marketing subject lines

7. Keep it short
For example:
• Hey (As made famous by Barack Obama)
• Psst
• Oops
The most successful subject lines
are under 50 characters

8. Create numbered lists
For example:
• Seven reasons you need a blog
• 9.27 tips to survive your first year in business
• Five cold emailing templates to boost your campaign
Outline what your reader can expect to learn in
your email with a numbered list.

9. Cultivate curiosity
For example:
• Why SaaS sales is about to change
• The most valuable thing I ever learned about fundraising
• We just added our best feature yet!
Give your readers enough information to pique their
interest, but not enough to satisfy it.

10. Demand attention
For example:
• The most important email you’ll read all day
• New webinar February 27th - Sign up today!
• Still paying attention?
Sometimes the best way to get someone’s
attention is to ask for it.

11. Crack a smile
For example:
• The best worst marketing email ever
• So a salesperson, engineer, and founder walk into a bar…
• Yeah, we’re still talking about Kim Kardashian’s ass (Made famous by Buzzfeed)
If your subject line makes your reader laugh,
they’re going to want to read more.

12. Use parentheses
For example:
• Seven dos (and three don’ts) of SaaS sales
• Deals that make us proud (unlike our nephew, Steve) (Made famous by Groupon)
• Do NOT open this email (You know you want to...)
Provide more context or humor to a subject
line by utilizing parentheses

13. Say goodbye
For example:
• Goodbye from Close.io
• It’s not you. It’s me.
• Permission to close your account?
Can’t get certain subscribers to open your
emails? Maybe it’s time to break up.

14. How to write really good subject lines
Your first subject line won’t be perfect.
Neither will your second, or fifth.
So write ten subject lines for every email.
Choose the best one, and measure the results
