Best Email Subject Lines

Here’s our collection of our Top 50+ Best Subject Lines. We send millions of emails every year which gives us a lot of room for testing and collecting data.

We wanted to share with you some of our best performing emails. Remember though a great subject line will get you the open but you’ll need it to make sense to get the click. We’ve sort them by category to make them easier to navigate. Enjoy!

Curiosity

These subject lines are all aimed to pique your curiosity, create an open loop and force you to open to close that loop. Anytime you can have them read the subject line and ask themselves a question they’ll be more
likely to open afterwards.

1. Bad news
Using the bad news is well known for performing well. Humans are attuned disaster and fear so bad news fits right that. Just be careful you aren’t actually delivering bad news and figure out a way to twist it so it still make sense.

2. You asked for it ;)
What did I ask for? Works well when you actually have subscribers anticipating this email.
Use it in conjunction with a pre email like ‘Would it help you if I…’ and follow up on that original email.

3. Have you seen this?
Questions always work great and this one is no different.

4. [Special Training] Big Announcement
Everyone loves training, especially when it’s special AND includes a big announcement.
Simple but effective.

5. Kind of weird, but VERY profitable.
One weird trick that scientists hate! Weird tricks always work and they are even better when profitable.

6. Dude.
I think this one just catches you off guard. Dude what? Plus it feels more informal and as if it could be from a friend.

7. Hey
Amazingly simple and very effective. Sometimes less is more and this is a prime example.

8. Ok now this is…
Anytime you use a … MAKE SURE to connect your next sentence.
For example if the subject line was ‘Ok now this is…’ then the first sentence would be ‘…the best video training I’ve EVER seen.’

9. He was wrong..
Similar to above except it also touches on a gossipy aspect. Who was wrong and about what?

10. 5618411832 (93s)
A bunch of random numbers, wait it’s actually a phone number and it’s 93 seconds? When doing my research this one even caught me off guard a little bit. Being different is good in the inbox.

First Name

Everyone will subconsciously see their first name and it’ll grab their attention. This technique works great for announcements and questions.

11. I have Good News [First Name]!
The opposite of our bad news subject line. Who doesn’t love (personal) good news?

12. [First Name], just give up
The second I wrote this one I knew it’d perform well. It also received quite a bit of negative feedback. This is a pretty ‘shocking’ subject line and will tend to polarize. Make sure that the content for one like this is positive.

13. [First Name] are you Overwhelmed?
Most people feel overwhelmed. I know I have my moments. This speaks to their inner struggles.

14. [First Name], Please accept my apology
This one piques curiosity while also feeling honesty. Just be careful it’s not gimmicky.

15. [First Name], Did You Get Your Free Gift?
At the end of the day you can’t beat free.

Transactional

Transactional emails such as login details, receipts, welcome emails and notifications account for the highest open rates. Because of that remember to use them for marketing as well.

16. [The Academy] Your Login Credentials
This was used in a promotion where we gave subscribers free access to our paid monthly membership. The initial plan was just to give access to the free portion, but due to an error we gave paid access. Most subscribers had heard about The Academy thus they were very surprised to receive this email and open rates where through the roof.

17. Re: [The Academy] Your Login Credentials
Similar to above, this email explained what had happened previously. Using Re: is a great way to reuse a successful email subject line while also furthering the story.

18. [The Academy] Downgraded to Free Level
After the weekend paid access we had to downgrade subscribers back to the free level. Similar results to the first email as far as opens and responses. Be careful though because you can cause a support nightmare.

19. You made a sale!
This was sent to affiliates and is actually a transactional email. It also has one of the best open rates out of any email we sent.

Free

What can beat free? Great for when you’re sending out pure no strings attached content.

20. [Free] Over The Shoulder Case Study
Case studies always do great and everyone loves the concept of peeking over your shoulder if you’re an authority.

21. [Free Software] Youtube Spy Tool
Nothing beats free software.

23. [Special Training] Your Questions Answered
Everyone likes to get their questions answered plus they are curious what the training is about.

24. New Training Get It For Free (For A Short Time)
The urgency of this email makes it perfect. We’ve released a new training, you can get it for free BUT only for a limited time.

Honesty

Honesty is the best policy. Well not always but it definitely has it’s place in our arsenal of subject line techniques.

25. I need your help
This works great if you’re thinking about creating a training but want some feedback and to create anticipation for it.

26. Can I Get Your Feedback?
Similar to above.

27. My Blatant Bribe
We used this for a giveaway. I think it’s a great subject line for contests, giveaways and even bonuses.

28. Frankly, I’m a little surprised..
A logic based email focused on why they haven’t done something yet. Make sure you’re sending it to non­buyers.

29. 99% of you haven’t seen this…
Good way to announce a brand new training.

30. This mornings Raffle Winners are…
Everyone’s excited to see if they won.

31. Only $20. Only 24 Hours.
If the product is cheap then why not mention it? Also includes time based urgency.

32. ☛ Only $1
Doesn’t get any cheaper than that plus the pointing finger draws your attention.

Personal

Using details from your own life can work great for emails. Letting your personality shine is ALWAYS a good idea in emails and this category just takes that a step further.

33. OOOPS I Did It Again… Pink or Blue?
Joe was announcing his wife’s pregnancy and introduced a Buy One, Get One Free offer.

34. I can feel the love…
This was a followup to the previous email. We received a lot of very nice messages and this was in response.

35. 32,000 feet above Charlotte (special announcement)
Ben had a few thoughts while on his recent flight and wrote the email in air while traveling. A great idea especially when you want to write off a quick email.

36. Would it help you if I…
Another great subject line to build anticipation for a training. Plus you can gauge response to figure out if it’s worth creating.

37. What I Learned from the Wolf of Wall Street
We had recently seen the Wolf of Wall Street so it was personally relevant. Plus many people at this point had seen or at least heard of the movie.

38. Here’s The Wolf of Wall Street Notes… (as promised)
We put a PS in the previous note that read “P.P.S. I took about a page or two of notes from the event. If you want the notes from the event just reply ‘I’m excited for tomorrow’.” We hadn’t planned on publishing the notes but after a HUGE response we decided to. This email worked well because of the anticipation from the previous email.

Shock Value

Shock value works there’s no doubt about it. Use it sparingly though or you’ll build distrust among your subscribers.

39. I got my @ss handed to me…
Whoa now, a curse word in an email subject line? You bet your butt it got opens.

40. One Word… CRAZY!
People can’t help but find out what’s so crazy.

41. Please Stop
I KNEW this one would crush. I also knew it’d probably get some really bad feedback. It met both expectations. The storyline made sense but you still have to decide if pissing a few people off is worth higher open rates.

42. Holy Shikees Make A Sale While On The Training
Shikees isn’t much of a curse word but enough to get your attention. I think the benefit really drove this one though.

43. Video Marketing will NEVER be the same…
It’s a very BOLD statement to make but that’s okay if your email backs it up.

Benefit Driven

Answering the ever important question ‘What’s in it for me?’ concisely within the subject line.

44. The #1 Reason We Have Grown 100%+ Year Over Year
If you like the person or company you receive this from you’re almost guaranteed to open it.

45. FWD: From 1 Product to Over $20 Million in Annual Revenue
What’s great is this was a completely true story. It was a great TriggerCast interview with Ajit.
Joe framed it as a forward. A good way to promote someone else’s content.

46. 7 Customers in 8 Days
This one almost sounds too good to be true but who can resist.

47. CHECK IT OUT ==> Local Marketing Profits on Autopilot!
Grabbing attention with the beginning and then proving why it’s relevant. It’s the type of subject line you can use when your list is segmented well or you know your demographics.

48. [45x The Leverage] Do Yourself a Favor & Watch This…
Everyone wants (or needs) more leverage in their business.

49. Horse & Buggy or Bullet Train (you decide)
Personally one of the favorites. It easily paints the narrative of using an ancient method versus the benefit of modern technology.

50. 20 calls & 16 email leads in 7 days + I’ll tell you how to do it
A great way to concisely introduce a case study or training. As you can see using numbers in benefit driven subject lines saves space and helps grab attention.

Time Based

Urgency and scarcity makes sells. If you do online sales you should be running time based offers. Live webinars
also happen on a specific time.

51. Tuesday’s Meeting
I think it performed so well because subscribers thought it might have been an in person meeting they had already agreed to.

52. Can you make it to this?
A great way to get someone to check out a webinar.

53. Tomorrow, Things Change
Typically used in conjunction with a training webinar so good it’ll change the way you do business OR a big announcement.

54. [4 Hours Left] This is it folks
Using time in the subject line works very well as you’ll see in these next few emails.

55. [12 Hours Left] I cant keep it open any longer…
When it closes, it closes. This gets subscribers to check it out now.

56. Only 6 Hours left… more winners!
A special twist, this email gets opens because people are also curious if they won.

57. You Missed It? Seriously…
Good for webinar replays.

58. Last Call…
If you don’t want to use time in the subject, this is a good alternative that performs well.

Don’t forget to test email subject lines against each other to see what wins with your subscribers. In time you
should have your own vault of high performing subject lines that worked well with your list!

Remember that when you send out emails is also very important. Test different days and different times.
Also inserting images and GIFs into emails can greatly increase CTRs.
