Do you know how many emails are sent daily in 2024? Roughly around 361 billion. Every. Single. Day.

This means that inboxes are constantly overflowing, and having your email noticed is a real feat.

This is particularly true for cold emails, where you’re reaching out to someone who doesn’t know you.

The key challenge here? Coming up with a subject line that grabs attention and gets to the point. All in just a handful of words.

In this piece, we’re going to show you how to craft those killer cold email subject lines – the kind that makes someone stop and think: ‘I need to read this’.

Let’s jump right in:

What is a cold email subject line?

A cold email subject line is the first line of text that a recipient sees when they receive an email from someone they haven’t previously interacted with. It typically happens in a professional or business context.

The purpose of a cold email is to introduce oneself, a product, a service, or a proposal to someone who may not be expecting this communication.

Why cold email subject lines matter

Cold email subject lines matter a lot because they often determine whether the email gets opened or ignored.

In a world where inboxes are constantly flooded with messages, the subject line is your first and sometimes only chance to grab somebody’s attention.

Here’s why they’re such a big deal:

First impression

The subject line is the first thing a recipient sees. In many cases, it’s your only opportunity to grab the recipient’s attention. A well-crafted subject line can make the difference between your email being opened or relegated to the trash folder.

Email open rates

The effectiveness of a cold email campaign is largely measured by its open rate. A compelling subject line will boost the chances of your email being opened and read.


People are wary of spam and phishing emails. A clear, professional, and relevant subject line keeps recipients at peace about whether your email is legitimate and worth their time.

“Quick question”

It’s perfect for when you genuinely have a quick question that needs a straightforward answer. The “Quick question” line has been popular for quite some time now. While it’s been around, for some target groups it still might work very well. As always, it’s best to test it out yourself.

Cold email subject lines – best practices

To further boost the effectiveness of your cold emails and their subject lines, follow our best practices:

  • Attention-grabbing – since the recipient doesn’t know the sender, the subject line must be compelling enough to prompt them to open the email. It should stand out in their inbox.
  • Relevance and personalization – the subject line should be relevant to the recipient’s interests, industry, or current needs. Using the recipient’s name or referencing their company can make it more personal and engaging.
  • Clear and concise – it should be straightforward and convey the email’s purpose without being misleading or overly vague. Lengthy subject lines can be cut off in the inbox, so brevity is important.
  • Professional tone – maintaining a professional tone is essential, especially in a business context. It should be respectful and not overly familiar or casual.
  • Value proposition – often, it’s effective to include a value proposition – a statement that clearly articulates what the recipient can gain from opening the email.
  • Avoid spammy language – overuse of capitalization, exclamation marks, or salesy language can make the email look like spam and reduce the chances of it being opened.
