How to create your ICP with AI

If your cold email subject lines don’t hook your prospects, they won’t read your emails. No emails read → No replies → No meetings booked → No growth opportunities.

So, how to write subject lines that boost conversion rates?

We analyzed the subject lines from 400M+ cold outreach campaigns to find out what works, and what doesn’t.

Here are 3 proven tips that will get your emails opened 🚀

Tip #1: Keep your subject line short & sweet

Your email subject line should be between 1-8 words (even 1-word subject lines can be successful).

It needs to grab attention and communicate value without taking up a lot of space. Readers should click on it after 1 look.

In fact, we found that open and reply rates decrease on average with every extra word you add to a subject line:

Your subject line should also be short enough to appear in full on mobile.

A subject line that looks like this on the recipient's desktop:

…will be cut short on a phone screen:

Tip #2: Ask a question only if it’s relevant

You might have heard that asking a question is the best way to engage with a prospect. The strategy is to provoke a response and make leads open the email.

So, are questions a proven way to get people to open an email?

According to the data, not necessarily.

Adding a question to your cold email subject won’t guarantee success. And if you try to over-optimize by adding multiple question marks, this will hurt your open rate!

Here's how to add questions in your subject lines:

→ Be specific - ask a question that addresses the prospect’s specific pain point, e.g., “Need help with {painPoint}?"

→ Challenge their expectations - provoke a response by surprising them, e.g., “Happy with 50% open rates?”

Tip #3: Add urgency

Your prospect should have a sense that they need to act on your message now instead of letting it get lost in minutes. The action they’re taking should be clear and easy to follow.

Using all caps, too many emojis, or exclamation points doesn’t lead to higher open rates. Also, using too many of them can get you marked as spam!

Here's how to add urgency and emotion without being spammy:

→ Make an exclusive offer,

e.g., “an exclusive gift for you, {firstName}"

→ Add fear of missing out,

e.g., “Invite to the event of the year, {firstName}"
