Cold emails generate leads. They generate interest and buying intent. Cold emails are the foundation of the outbound lead-generation process of startups and big companies alike.
We’ve tried cold emails ourselves, and have found some interesting insights.
In this post, I share some of our insights about cold email subject lines that work. Some of them are counterintuitive, others support the advice of cold email gurus.
Email open rates depend on many factors. The subject line is one of the most important but is not the only factor.
Your email may not be opened if:
If your company email domain’s health is poor or your emails regularly land in promotions or spam, those would be bigger issues to fix than your subject lines.
Your subject lines don’t matter if the prospect doesn’t even see your email pop up in their inbox.
So, fix that first. If you've already gotten that fixed, let's dive into what makes a good subject line.

Most articles on this topic have headlines like the ones above (this one is no different).
As you might have seen, the article that you are reading right now is not the only resource on subject lines.
While there are plenty of subject line lists out there, it’s important to keep in mind that copying subject lines that have worked for others won’t work for you.
Yes, this is another article with a list, but your focus should be on the insights gained from the subject lines that worked, and not on copying them right away.
Here’s why:
This post talks about subject lines that have worked for us. What’s important is to take our learnings and insights, and adapt them to your use case.
Now, let’s get into it!
Will Allred from Lavender recommends keeping subject lines to 2-3 words max. We decided to test it out.
Guess which subject line did better?
Come on, take a guess.
If you went for (b), you are right. Will was right, and we’ve seen this pattern repeated across different subject line experiments. A shorter subject line that encapsulates part of the promise of the longer one typically tends to do better in both open rates and reply rates.
Guess which subject line did better?
Our hypothesis was that the latter might get more opens. It’s more specific about who we are projecting our product’s superiority against.
Surprise, surprise!
It was the former. Superiority against the market got higher open rates than superiority against the competition.
Guess which subject line did better?
Perhaps relating to the keeping it short principle, (a) did far better in open rates. While both the subject lines talk about solving a specific problem for the prospect’s team, the former is shorter and speaks to their problems rather than our product.
The framing in the second one makes it about the platform. And that’s not a great perspective if you want to show that you care about the reader’s problems.
Including “hope” in our subject lines improved our open rates.
The positive language and the curiosity that it builds help cross the sales-y email barrier in your prospect’s minds. This is one of those areas which can get stale really quick if not used properly.
Some subject lines focus on not seeming sales-y while the email is explicitly sales-y. Since we were reaching out to revenue leaders, we know that they would read through any such attempts.
So for our cold emails that were specifically focused on booking meetings, we tried a new approach - being actively anti-sales-y.
“Here’s another gimmicky email [No, it’s not]” was a subject line that we used, and it worked pretty well. This subject line breaks the fourth wall in a sense (I’m not a salesperson pretending to be someone else) while also targeting a common enemy (nobody likes gimmicky emails).
Some of the most useful cold emails are the ones that provide value right out of the gate.
We shared one of our blog posts in our cold emails to prospects, and many of them reached back to thank us for the resource.
The subject line was the same as the title of the blog post. It was about “3 ways to improve your sales demos”, it was relevant to our audience, and they liked it. Here's the complete blog post on improving your sales demos. (It's actually got 6 ways, not 3).
Yes, this wasn’t personalized. But it was relevant and provided value.
And it got tons of opens and replies.
Guess which subject line did better?
Yeah, you get the hint. It was (b). This might be quite audience-specific, but the difference was immense.
People want to see the value and don’t like feeling like misers.
Free offers are great, but they should be a cherry on top of the value and not the leading reason to open (and respond to) the email.
There’s lots of talk in the town about whether break-up emails work. The subject line looks like this:
“[First_name], congratulations! You’ve made it to the break-up email”.
It’s enticing, but does it work?
Not
Some prospects read the entire chain of emails after the break-up email and realized that our offering was relevant to them. This may not have happened if the break-up email hadn’t gotten them to finally open and pay attention.
Getting better at cold emails for lead generation is a continuous process.
The learnings and insights about prospect psychology stay the same.
The specific subject lines, ask, and other tactics keep evolving over time.
To keep abreast of new ideas and experiments going on in the field, we recommend following email gurus like Will Allred of Lavender (he posts helpful content every day on LinkedIn and TikTok, and knows what he’s talking about). Also, check out his blog post with Dooly.
Also, if you are curious about how AI tools can help you write better emails, check out Lavender, Regie.ai, Copyfactory, and Jasper AI.
AI for writing cold emails and even entire sequences is evolving pretty fast, and there’s some interesting innovation happening in the area.
