What’s Included in the Important Email Subject line?

Email subject lines are the hook that makes people want to open your email, read it and take action. They should be crafted carefully so as to not only grab attention but also influence how your recipients will engage with the email content.

Let’s look into some of the best practices regarding important email subject lines:

Conveying importance is what separates the good subject lines from the bad ones. If you write something like ‘Blog Post’, it won’t make much of a difference to your readers. But if you say, ‘XX tips to help your blog grow by XX% in XX days!,’ now that’s important.

If people notice an important email enough to open and read, they are likely to act on it too. This is why you should focus more on what’s in it for them rather than yourself.

When writing an email subject line, try to use the words ‘you and ‘your.’ For instance, if you are writing about a new product launch, don’t say something like ‘New Product Launch!’. It won’t have any impact on your readers. Instead, try something like ‘Your New Product!’ or ‘Introducing the new XX product!’

Another important aspect is to make sure you convey what’s in it for them. If it’s about a new release, say ‘Download the new version of our app’ instead of saying ‘New Release!’ or ‘New Version!’

Importance of email subject lines

A recent study found that email subject lines are one of the most important parts of every email. The study showed that emails with good subject lines get opened 10-15% more than those without them.

The experiment was conducted on two groups of people; each group had around 8,000 people in it. One group received an email with a good subject line, while the other group received one without a subject line.

The group that was sent emails with good subject lines had an open rate of up to 15%. Emails without subject lines only had about 10% open rates.

Tom Osenton is the CEO of Hubspot, an inbound marketing company. He said that when they conduct their own research, they have noticed that people try to be more creative with their subject lines.

He says that the majority of marketers use short and descriptive words or sentences in an email. Also He mentions that this is a good strategy for email marketing, but not all the time.

For example, if you’re sending an invitation to your friend’s birthday party, you’re going to mention the word “birthday” in the subject line.

But if you were trying to sell a product or service via email, people are more likely to open your email if it has a good headline. According to Mr. Osenton, this is because marketers are focusing on how many emails they can send to their customers, but they don’t think about the quality of what they’re sending.

This also applies if you own a business and send newsletters to your clients. If possible, try to make your subject lines catchy and descriptive so that they will grab people’s attention.

The conclusion of your email should be driven by the tone and purpose of the rest of your message. If you’ve included a call to action, for example, it may not be necessary to include one in this final statement. However, if you need to reiterate what is needed from recipients or thank them for their time and commitment, make sure that these are also expressed clearly in this section.
