The world of digital marketing is constantly changing. Every time you feel like you’ve got the hang of SEO, Google tweaks its algorithm. Social media platforms come and go (does anybody remember Snapchat or Vine?). However, among this perpetual transformation, one thing remains constant: email marketing.

Don’t assume that because email marketing is as old as the internet itself, it has become obsolete. Email has a 300% ROI, meaning that for every dollar invested you get approximately $30. That’s huge! Moreover, people that convert through email spend 138% more than those that don’t receive targeted email messages.

Email marketing writing service campaigns are still effective – there’s no doubt about it. The question is: how do you get these impressive results?

Here’s what you need to know about how to write subject lines that will spark interest and boost your open rates:

Keep the Subject Line Short and Concise

As a rule of thumb, try to keep the subject line below 30 characters. Anything longer than that becomes unreadable, tests the reader’s patience, and seems a bit forced and desperate. We know it can be tempting to add multiple keywords or attempt to make the subject line as compelling as possible. But, when it comes to email marketing – short, sweet, and to the point is your best strategy.

Keep in mind that prospects should be able to read the subject line without having to open the email. Otherwise, you’ve lost them.

Make Sure Prospects Can Read Your Emails on Their Smartphones

Reports show that 55% of emails are opened from mobile devices. Read that again: more than half of emails are viewed on a mobile platform. Adapting your strategy to include smartphones and tablets is, thus, paramount.

One excellent way of making your emails mobile-friendly is by following the 2-2-2 rule:

  • The first two seconds are crucial: it’s how much it takes the average reader to decide whether they will open your email or not. And, you’ve guessed it, it all has to do with the subject line.
  • The first two words of your subject line are the most visible and memorable. Use those two words to give essential information about the content of the email and what’s in for your audience.
  • The third 2 of the rule refers to urgency. Ask yourself: Can prospects tell from the subject line that it’s in their best interest to open and read the email today and not save it for later?

Insert a Question in Your Subject Line

Here’s a common and effective method of triggering your prospects’ curiosity: ask them a question. Of course, if you want to generate results using this trick, you need to be aware of your audience’s needs and problems and ask questions that they are eagerly waiting for an answer to.

For example, if you are a travel agency, and know that most of your prospects tend to let winter holidays planning for the last minute, you could send them a friendly reminder asking them: “Have you booked your Christmas flight yet?” Not only that they are more likely to open an email that asks a question that interests them directly but they will also perceive you as a brand that is customer-oriented and not just sales-driven.

Insert Emojis in Your Promotional Emails

This tip may be a bit controversial as many business owners prefer keeping their marketing messages quite serious and professional. And, most see emojis as childish and a bit silly. Of course, using emojis might not be in line with your brand, and that’s okay. But, if your tone is friendly and relaxed, then you should consider including some fun emoticons to your subject line.

Emojis will make your email pop-up in your prospects’ inbox and help them relate to your content. Not to mention, it is a great way of conveying a lot of information without using too many words.

If there’s something you should take away from this article, it is that writing a good subject line is all about knowing how to appeal to your specific audience. Use the above tips to ensure your email marketing campaign is bringing in the most ROI for your business.
