  • What specific steps can be implemented to improve email open rates?
  • What are the strategies we should implement that will stop subscribers from ignoring our emails? 

To be honest, there is no magical stick that when applied will boost open rates immediately, but when we are dealing particularly with low open rates, two factors highly need to be considered   —the “subject line” and the second one is “customer’s relation with the brand.”

There are so many strategies you can apply in your subject line which we will discuss later in this article. For instance, you can have these quick notes in your mind. 

Your subject line should be;

  • Short, Personalized, and Relevant to your audience.

Fortunately, Klaviyo has various tools to help you in crafting an effective subject line that’ll not only improve open rate but can also lead to better conversions. 

So kindly stick around till the end, as I’ll be sharing really helpful and practical tips on how you can use Klaviyo at its full potential to craft an optimized subject line. 

The Importance of Subject Lines.

Why Do Subject Lines Matter? 

It’s the subject line that your subscribers will notice first as soon as they open their inbox. 
Based on the influence that subject line creates on their brain, they’ll either open the email or ignore  it . 
Inshort, the subject line holds the power to influence the decision of readers. That’s why it matters most in email marketing. 
Furthermore, It’s a great way to tell your subscribers- what’s inside the email in a more concise way, considering the fact that average reading time is decreasing. 

You might’ve noticed, that nowadays we’re just skimming through the sentences rather than reading completely, so it’s advisable to have a strong, clear, and concise, and relevant subject embedded with certain psychological tricks to increase open rates. 

The impact of subject lines on open rates and overall email performance.

Let’s keep it simple: If your subject line is not optimized then there is only one possibility that can occur: a decline in open rates.

Therefore what’s essential here is identifying the factors that are causing this phenomenon. 

Figure out, what the factors causing low open rates. Is your subject very broad or sounding like a scam? Are your subscribers able to relate to it or not? Is your subject line so sales that people, after reading it, choose to stay away? 

Similarly, there are various such factors playing their role in backend, causing a negative impact on open rates and overall email campaign.

Without figuring out what the actual faults are, you will not be able to design or optimize the subject line most effectively. 

Optimising the subject line is not just about rephrasing its word and making it exciting but is more about knowing where the main crack is and then cementing it accordingly. Only after this can you hope for better results. 

Do’s and Don’ts in the Subject Line

While crafting a subject line marketers often willingly or unwillingly end up doing lots of things that they’re not supposed to do.

Which either creates a negative impression on subscribers or gets hit by the spam filter.

There’s no doubt that email marketing has more ROI compared to its alternatives.

However, to avail such high ROI one must follow fair practices, and ethical and legal approaches while designing subjects line for their campaigns.

lets have a look on what you can do and what you shouldn’t with respect to the subject line.

1. Know your Audience/Subscribers

Here, understanding your audience means the people who are already present in your email list. We have to analyse these profiles in particular and not outside of the email list.

However, you can relate this profile with those who have not joined your email list yet but have lots of similarities in common; such as all are into modelling, fashion designing or are fitness enthusiast or pet lovers or biker and so on.

2. Personalisation Tactics

Personalisation is not just limited to adding first and last name in the subject line, it’s beyond that. 

The more personalised and relevant a subject line sounds to a reader the more chances are that he’ll interact with it. 

How can you make the subject line personalised? 

Simply by utilising the data which you’ve collected while doing research about your customers. 

Especially, when it comes to E-Commerce email marketing incorporating the name of your customers in the subject line is not alone enough to entice someone to open your email. 

Even I do also receive tons of emails from E-Commerce brands, stating my name in the subject line, offering enticing deals and discounts, still it’s not enough to convince me to open the email. 

Because I already know what’s there in the email and what’s the main motive behind sending that email to me. Obviously, they are trying to sell me something. 

And, this is what being a common man I hate. I don’t like someone trying to sell me something when there is no intention of buying it at that moment. 

Yes, timing is a crucial factor that must be considered while presenting any offer in front of your customer. 

  • What you are selling should be —— relevant
  • How you are advertising it should be —— compelling
  • Timing of sending emails should be Ideal i.e. customer should feel – “Oh, what a coincidence.”

When we say personalization there is no space left for randomization. 

You have to figure out the right time to send the email so that customers won’t leave it without opening it. 

How to identify the right time for sending emails? 

The right timing is when they’re looking for something to buy. Klaviyo can easily provide this information as it tracks visitor’s every movement in your store, especially, search and view history, wishlist, abandonment details, and much more. With this data, you can easily predict the most ideal time to send the next email. 

3. Utilising emotional & Psychological words

You can use some powerful words to make your subject line more attention grabbing.

For this you can also use AI tools to craft strong hook based on personal traits of your audience.

AI tools like, ChatGPT, Google Bard can help you with this.

For transforming your subject line into a strong hook you can apply the following tone. 

  • Curiosity & urgency
  • Emojis & questions
  • Numbers, facts & data
  • Fomo
  • Benefits & USP’s
  • Testimonial
  • Social Proof, Customer stories
  • Problem, Pains & challenges
  • Latest deals
  • Specificity
  • And, please make sure to optimize the preview test as it gives the second tease to open the email.

4. Performing A/B Testing

In a world of email marketing, running an A/B test is a secret tool to optimise an email campaign in a more effective way.

By performing A/B test you can obtain a perfect working formula for your subject line. Which can bring a significant engagement and conversions.

A/B testing involves sending two versions of emails to test their performance, to see which performs better in terms of open rates, CTR, conversions, and so on.

As here we are particularly focusing on the open rates we can test different forms of subject line.
