Digital Strategy Email Marketing

Introduction

 

Are you wondering, what is email marketing? Well, the simplest answer is that it’s still one of the most cost-effective and conversion-focused channels available. According to the Data & Marketing Association, email marketing delivers an average ROI of £42 for every £1 spent, higher than any other digital channel!

 

However, you must have a strong base of email subscribers to utilise the real power of email marketing, to help turn that interest into action. Throughout this blog, we will explore how to take your email subscriber list and convert those subscribers into paying customers using strategic content, smart segmentation, and handy automation.

Understand the Value of Your Email Subscriber List

 

It’s handy to have a large subscriber list, but size doesn’t always mean success. The part that really matters is the engagement. An email list that is interested and active will outperform a large, inactive one. 

 

This is where audience segmentation comes into play, by dividing your email subscriber list based on various factors. These factors include behaviours, purchase history, personal details, or preferences, and you can send more relevant and targeted messages to improve your chances of making a sale. Marketers who use segmented campaigns can see up to a 760% increase in revenue, according to Campaign Monitor.

 

Create a High-Converting Welcome Email Series

 

First impressions count, and a welcome email is your first real opportunity to make a lasting impression. Your welcome email is often the first real touchpoint with a new subscriber, and it carries weight. In fact, open rates for welcome emails are around 4 times higher than other marketing emails, and they generate up to 10 times more clicks (Mailmodo).

From discount offers to helpful content or a freebie, an automated welcome email series can help you build trust from the very start. Try to offer real value with a clear call to action that nudges new email subscribers towards their first conversion.

 

Nurture Email Leads with Relevant Content

 

Once you’ve reached out with a valuable series of welcoming emails, it is time to nurture your email leads. This means going beyond the sales push, trying to think about what your subscribers need to know, what they will find valuable, how to make your emails relevant to them and not just what you want to sell. There are various ways to help do this, such as using content marketing techniques:

 

  • Share how-to guides or tutorials
  • Include case studies that show real results
  • Highlight testimonials to build social proof
  • Customer testimonials or reviews to build trust
  • Behind-the-scenes insights into your brand, team or process
  • User-generated content such as photos, reviews or social mentions
  • Interactive content, like quizzes or polls, to boost engagement
  • Curated resources or roundups that save your audience time
  • Educational blog content summarised with links to read more
  • Product demos or explainer videos that reduce purchase hesitation
  • FAQs or myth-busting content that handles objections before they arise

 

Consistency also matters; readers will forget you if you send too few emails, and too many will cause fatigue, leading to unsubscribing. Try and find the balance with a timed schedule that keeps your email subscribers engaged without overwhelming them.

 

Schedule Impactful Newsletters

 

Scheduling is a key actor in turning email subscribers into customers, as it allows you to strike at the optimum time. When sending newsletters, it is your chance to keep the conversation going and stay relevant. Newsletters that are effective, well-written and creative should aim to educate, inform and sell. You may want to include product spotlights, seasonal tips, thought leadership pieces, industry news, offers and insights. Set a schedule that is automated and right for your audience to keep your brand visible and informed, helping to convert email subscribers over time.

 

Optimise Your Email Marketing Metrics

 

Timing and personalisation are a huge part of email marketing, as personalised emails deliver six times higher transaction rates, yet 70% of brands still don’t use them (Experian). Sending emails based on personalised factors can help deliver the right message at the right time, such as sending emails based on behavioural triggers like abandoned baskets or page views. Using audience segmentation to group users by interest or lifecycle stage can improve the relevance or including dynamic content that is tailored to each subscriber. Try to consider these things when creating your email content, as they will help improve email marketing performance.

Create Clear, Compelling Calls to Action

 

Call to actions are sometimes quite forgotten, yet they really help guide readers in the right direction and are a big part of email design. A well-crafted email with no call to action will struggle to deliver results. Whether it’s “Shop Now!”, “Download the Guide”, or “Claim Your Code”, your CTA should be easy to spot and even easier to click.  As seen in the email to the left, Moonpig added a timer to create urgency while staying informative, and provided a clear “Shop Birthday Cards” option at the bottom, making it simple for the audience to navigate.

 

Action-led language is vital in a strong email strategy, as it helps to encourage immediate engagement, and, where appropriate, create urgency with phrases such as “Ends Tonight!” or “Limited Stock”. It helps to keep your message short, direct, simple yet relevant to the content you’ve provided, as every email should focus on one clear objective, and your CTA is what should relate to that, whilst guiding your subscribers to take that next step.

Tools and Automation for Smarter Email Marketing

 

Emails don’t always have to be done manually, which is where email automation comes in; platforms such as Mailchimp, Klaviyo and HubSpot allow you to set up behaviour-based automations for segmented audiences that run while you focus on other things. By utilising these websites, you are able to:

 

  • Send emails based on lifecycle stages (welcome, post-purchase, re-engagement)
  • Segment your audience for optimum impact
  • Personalise product recommendations
  • Re-target inactive subscribers
  • Schedule emails so they send at the optimum time

 

Automating your emails not only boosts consistency and saves time, but it also drives real results – with one in three people who click on an automated message going on to make a purchase, it’s a no-brainer.

 

Final Thoughts

 

Your email subscribers signed up for a reason – they’re interested. With the right mix of segmentation, smart content, and automation, you can convert email subscribers into loyal, long-term customers.
