50+ Email Subject Line Examples For Cold Outreach Campaigns

subject line examples

This post is a part of my complete series on cold outreach email framework for 2020.

The first thing you need to focus on for digital outreach is your email open rate. A subject line that piques interest is key. 47% of emails are opened or discarded based solely on their subject line.

The language and emoticons you use in your subject line can have a major impact on the extent to which you encourage influencers to open your emails.

Only then you’d be able to get a response, follow up and get your desired outcome from your outreach campaign. The best email subject lines are creative and informative without giving too much away.

There are proven formulas you can use. Let's go over some best practices and examples associated with them. So you'll have the right perspective on how to put the email subject line examples to good use.

Highlight A Commonality

Before you start considering subject line ideas, you must check if you have something in common with the prospect. A subject line establishing a common connection is the most effective there is. No other subject is as likely to get opened than this one.

Look at your prospect's LinkedIn profile, for example. If you have any connections in common, may be they could introduce you. If not, perhaps have something else in common, like being part of same college or group.

Personalize Your Subject Line

You need to make sure there’s enough personalization in your digital outreach for the reader to feel respected and appreciated.

For instance, you’ll get far more opens if the recipient's name is in the subject line. A study by Experian found that personalized emails have 29% higher open rates. Seeing their name in the subject line gets their attention.

In addition, the most reliable results come from taking a few minutes to study your prospect and then using your subject line to indicate that you know who they are and what they might need.

Make Subject Line Descriptive

Also, a study conducted by MailChimp concluded that short, descriptive subject lines are better than clever or cheesy phrases.

The subject line must also have a clear indication of what the email is about. Simply filling your prospect in on the basics or asking the question you intend to ask may seem bland, but it can be darn effective.

Emojis In Subject Line

Emojis in email subject lines have become a common occurrence in marketing and outreach. And it’s obvious that a subject line with emoji catches our attention more than a subject line without one. So the sooner you start using them, the better.

Keep them relevant to the context of your email. If you’re pitching a story about coffee, for example, then use a coffee emoji ☕. A random or general emoji won’t have the same impact.

There are a number of websites which let you use their emojis for free. All you need to do is just copy and paste into the subject line when crafting the email. These include EmojiCopy, CopyAndPasteEmoji, and GetEmoji.
