50+ Subject-Line Ideas to 5X Your Conversion Rates

50+ Subject-Line Ideas to 5X Your Conversion Rates

You’ve spent days in collecting all those email addresses and finally, you’ve got hundreds of impatient prospects sticking to their computers, tablets, laptops and cell phones, just to go through the “Golden Message” from you. If that’s what you think, we’re living on Mars.

Perhaps, you’re properly awake by now, wondering what you should send to the people who’ve thrown their addresses at you. But before they go to the real message of your email, you have to come up with a subject line that will make them so uncomfortable and confused that they have no choice but to read it.

Before we move on, let’s take a quick look at this great video from Volusion on email marketing and subject lines.

Creating a Subject Line of Your Promotional Email

That’s hard and the problem is two-fold:

  1. Perhaps your prospects don’t know the importance of your email or perhaps they’re smart enough to know what’s inside and don’t want to open it.
  2. The subject line of your email is either too good to be true or it is so bad that even your best friend won’t read.

Maybe, the root of the problem IS the subject line of your email. Maybe, the people are right to avoid it. But that doesn’t make you uncreative either. It’s simple a problem businesses face these days.

People have social media channels, messaging apps, mobile games, and awesome videos to pay attention to. Plus, they already have their inboxes full of sales promotion emails from several different brands, especially those similar to yours.

Why should they waste their time opening an email that talks about your product? They won’t unless they’re tempted to do so. And that’s the trickiest part of all.

As the title suggests, we’re going to share some of the best Subject Line Ideas that will make prospective customers open your email. Speaking of which, there’s something really important you should know before jumping to those ideas.

Email Open Rate

There are many factors that determine average open rate:

  • Your subscriber didn’t have any motive to buy from you. He became your subscriber because of the free gift you were giving away in exchange for email address.
  • You’ve not segmented your list properly. The subscribers you’re sending an introductory email to have already purchased from you in the past.

Anyways, let’s see what average email open rate actually is and where you stand.

SmartInsights analyzed billions of emails sent via Mailchimp, and they found out that the average email open rate lies between 15% and 25% depending upon the niche or industry. This is a difference of just 10% but it says a lot about different industries and how people see their emails. For instance, the restaurant industry has the highest email open rate of 24%, followed by health and fitness (23.4%).

And if your average open rate is between these two extremes, you’re safe! Even if it’s lower than the lowest, you’ll soon learn the art of making a huge impact. But before that, you need to know why it’s important to monitor open rates.

Your autoresponder dashboard has quite a few numbers, like:

  • Bounce rate
  • Open rates
  • Click-through rates
  • Complaints, and more

These numbers are significant, but the reality is, your email needs to be opened before you can gather any other information. And another truth is, you need to make your email count because your sale from the list is totally dependent on it. Apart from the brand name mentioned in the “From” line, the subject line is the strongest factor that encourages your subscriber to open your email.

Why Subject Line?

Now, going back to where we started, what makes your subject lines so tempting that people stop, click and read the message? Here’s what experts suggest:

  • Your subject line should “Provide succinct summary” within 40 characters – roughly 5 to 10 words.
  • The subject line should “Develop a sense of urgency” so that the reader will open your email then and there.
  • Your email’s subject line should “Match your content” because readers get easily annoyed with contradicting content.
  • The subject line should “Arouse curiosity” in your subscriber and inspire him or her to immediately open it.
  • The subject line of your email must “Convey clear and strong benefits” to the reader. The benefit can be a 50% limited time discount offer or free eBook.

Here is a comparison of two subject lines to let you decide which one’s more appealing.

  1. “Do my wicked email ways work in B2B?”
  2. “Major elements of B2B marketing – Summer 2017 Kit”

The first subject line may seem weird but it’s worth an open, isn’t it? It has almost everything we discussed above.

Subject lines are the point of contact between your subscriber and your message. So, make them count. The problem is you have to generate emails on regular basis.

For each of the messages, you have to create a unique subject line right from scratch. This is the reason why we have come up with 50+ subject line formulas to help you create an impressive subject line throughout the year.
