Email marketing can land you rewarding conversions, but first, you’ve got to fish for them.

We are all guilty of brushing over marketing tips, picking out keywords and working with what we’ve got.

But that is where you go wrong, you need to understand the concept behind the advice to ensure you carry out the approach in the correct way.

This guidance is most prominent in email marketing. The average person will receive around 90 emails per day, with most ending up in the ‘junk’ or ‘trash’ folder.

We have been taught that first impressions matter, we can judge how nice a person is by their facial expressions, how someone dresses or how someone presents himself or herself verbally – it’s the same with emails.

If you want your email to be seen and opened for that matter, then you need to shine through the others. For you to succeed in email marketing, your subject line needs to almost instantly persuade the user to take a look at what you have to say.

So, if you’re planning on setting up an email marketing campaign, then read this blog to teach yourself what the most successful email subject lines are. Remember, don’t brush through, take everything you can in and this will help you understand further.

Different types of email subject lines

The following tips are so important because they prompt the most engagement. When you’re sending out an email to new customers or existing clients then you will need to consider these pointers:


Before you click send, think to yourself, is this content relevant to your customer’s issues or current situation?

There’s no point offering your services when they’re already using them or provide the same. Consider, has this consumer subscribed to your email list for a particular reason? Are you suggesting something useful or are you going in cold? If you want your email to reach your customer, then you will need to keep it relevant to your audience.

You then need to ensure that your subject line relates to the content. Although clickbait is an effective way to get someone to open your emails, it’s frowned upon and could consequentially put you in the block list. If your subject line has no or little relevance to the contents, then you may as well expect a bounce.

Personalised approach:

Today there is mass competition to get emails opened and to close a sale, so much so that we forget one key element – emotion. It’s natural for us as people to connect more effectively face to face because we can interpret communication much easier. On emails, we are limited; people often tend to ‘guess’ how an email is coming across.

This reason is exactly why you need to relate to the customer and offer a solution to their potential problems or reassure them of what you’re suggesting. Also, you are more likely for someone to read your emails if you have shown your efforts to research them.

This could mean anything from looking at what the client has recently shared on social media or is looking for – then you can mention this in your email to show that you have taken your time to get to know them individually.


Nobody enjoys being pressured into a sale, that’s why you need to avoid using capitals in your subject lines. There are many clever ways to create a sense of urgency in your email, without coming across as too demanding. Your email attempts will most likely be ignored if it comes across predictable – so try using more persuasive language.

There’s a thin layer of ice when it comes to using urgency for your email marketing, however, step carefully, and you’ll start seeing results. By convincing people that they need to read your emails, you can ultimately expect your client to open your campaign. Remind yourself, be persuasive, not pushy!

Discount and Offers:

Everyone loves to receive an offer of some kind, whether it’s 10% off or buy one get one free, it makes us much more willing to take a look at what we can get for ourselves. If your email offers promotional content, then state what the customer can expect to receive in your email subject line. You want to make sure that they see this before anything else.

It’s quite exhausting cleaning out our inboxes from boring and ‘sales’ emails, but when we receive an offer or discount, then we’re nosey. It’s human nature that we are drawn to offers which is why if you’re looking for your email campaign to prevail, you can expect this approach to be one of the most successful.

Other points that matter a lot:

The length:

Think about it, it’s quite easy for a desktop user to see the length of your subject line, but most of the population use mobile devices.

Subject lines of emails are optimised so that the user can see the whole subject line instantly – instead, they’ll see the first few words. It’s important to keep your subject line short and catchy.

Send at peak times:

Sending your email at 10 pm or 5 am isn’t going to work for you, you need to research and think when your customer will be free and much more likely to see your email.

1 pm and 8 am are quite often the best times to send emails to your customers, one because they’re most likely on lunch and the other, you’ll hit their inbox first before any other emails.

Now for some examples:

If you came here for some examples to use, then lucky for you, we’re generous enough to help you with that. Take a look at these email subject lines and see the difference in approach.

  • ‘MASSIVE 50% OFF’
  • ‘HURRY limited time offer.’
  • ‘Hey, ‘Joe Bloggs’ can I have one minute?’
  • ‘Please see this.’
  •  ‘Important tips inside.’
  • ‘8 tips to get more sales.’
  • ‘Is it me you’re looking for? It may just be because…’
  • ‘It’s not 50 shades of grey, but it’s worth a read.’
