What is email marketing?

Email marketing is a digital marketing strategy in which brands and businesses send professionally crafted emails to targeted recipients to promote products, services, or content. It should deliver valuable information to a target audience to drive action.

An email marketing campaign can have different goals. The most common intentions set by businesses are to engage with potential or existing customers, nurture leads, increase brand awareness, drive traffic to a website, and ultimately boost sales or conversions.

A step-by-step guide to email marketing

In this email marketing tutorial, you'll learn to create a successful email campaign. Marketing campaigns must be carefully planned, from defining your objectives to production and analysing campaign results.

Step 1: Set Clear Objectives

Having a clear objective for your marketing emails makes it easier to determine the direction of your messaging. Establishing clear objectives also ensures that your email campaigns are aligned with your overall marketing goals, making it easier to define success metrics, whether it’s increasing sales, driving traffic, or nurturing leads.

How to do it:

Define your goals. For instance, do you want to increase website traffic, improve engagement, or boost conversions? The best way to determine this is to set SMART goals.

  • Smart
  • Measurable
  • Attainable
  • Relevant
  • Time-bound

For a better idea, here are some examples of well-defined goals:

  • Grow the email list by 20% in six months.
  • Generate 10% more sales from email marketing by the end of the quarter.
  • Increase open rates by 5% within three months.

Step 2: Build and Segment Your Email List

A targeted, quality email list helps you reach the right audience, and segmentation increases relevance, which improves engagement.

How to do it:

Well-placed sign-up forms can help you grow your email contact list. Use real estate on your website, blog, or social media, offering incentives like discounts, free resources, or exclusive content to encourage users to subscribe.

Segmenting involves organising contacts based on specific criteria. Some common segmentation categories you might consider are:

  • New subscribers vs. existing customers
  • Geography (location-based targeting)
  • Engagement (active vs. inactive users)
  • Purchase history or interests

Step 3: Choose the Right Email Marketing Platforms

A good email delivery service allows you to automate, track, and optimise your campaigns. Choose a platform that offers capabilities that complement your existing workflow. Some features you may need are email and marketing automation, A/B testing, segmentation, personalisation, and analytics. Some email marketing tools offer features that track a customer's past purchases which you can use for segmentation efforts.

Your email marketing platform should also seamlessly integrate with other tools that your team already uses, such as CRM, e-commerce, and social media platforms.

Step 4: Craft Compelling Email Content

The key to crafting high-quality and engaging emails is offering truly relevant content that encourages users or your audience to take action. This helps drive better open rates, click-through rates, and conversions — all of which are success metrics you may look for.

When developing the content for your email marketing campaign, thoughtful consideration must go into the entire structure. Here's a breakdown of how to create an email.

Create a strong subject line

Subject lines serve as the primary hook to get your audience to open an email. Keep it short to a maximum of 50 characters, but the fewer characters, the better.

Write engaging copy

Messages should be personalised with their names, while the tone should ideally be more conversational to make them easier to read. The best content offers benefits that explain what a customer may gain from using your product or service.

Use visual elements

Images, graphics, and videos are valuable content that supports your message. They're also a great way to showcase your product, service, or important features.

Include a clear CTA

The call-to-action is ideally limited to a maximum of four short words. Similar to the subject line, the fewer, the better. Some great examples are "Shop Now," "Learn More," and "Add to Cart."

Step 5: Personalise and Automate Your Campaigns

Personalisation improves engagement, helping audiences feel like you genuinely care about them. There are ways to automate personalisation to save time while ensuring timely and targeted email delivery.

How to do it:

Customise content using the recipient’s name, tailor content to their preferences, or recommend products based on previous interactions.

Automate email flows with your email marketing platform. Some essential messages you may want to send are:

  • Welcome emails: Sent to new subscribers, introducing them to your brand.
  • Abandoned cart emails: Reminding customers about items left in their shopping carts.
  • Re-engagement emails: Sent to inactive subscribers to encourage them to re-engage.
  • Behaviour-triggered emails: Automated messages based on user behaviour, such as browsing a product page or downloading a resource.

Step 6: Optimise for Mobile

Approximately 1.7 billion people access emails through their mobile devices, making it essential to optimise emails for mobile platforms. Not only can this enhance readability, but it can also increase engagement for its accessibility

How to do it:

  • Use a responsive email design that adjusts to different screen sizes.
  • Keep subject lines short for preview text to display properly on mobile.
  • Use single-column layouts to ensure readability and place CTAs prominently near the top.
  • Test your emails on different devices and email clients to ensure they look great across the board.

Step 7: Test and Preview Your Emails

Testing ensures that your email is visually appealing, functional, and effective. Think of it as the digital marketing version of quality checks for emails before it reaches your audience. Some effective ways you can implement this include:

  • A/B testing different email elements
    You can explore different subject lines, CTAs, images, or copy to see which performs better.
  • Test links and CTAs
    Ensure all your links are working properly and direct users to the appropriate pages.
  • Preview emails
    Different emails, like Gmail and Outlook, may display differently. The user's device can also affect the format. Check for desktop, tablet, mobile, and even iOS and Android.

Step 8: Send at the Right Time

Timing can significantly impact your success metrics. A good email delivery service should allow you to optimise when sending out your content based on time zones or historical open data.

You can also use the opportunity to experiment with different send times and analyse performance to find the best time for your audience.

Step 9: Monitor Key Metrics and Analyse Performance

Tracking performance helps you understand what’s working and where improvements are needed to boost your metrics in the next campaign. Review your email marketing performance regularly to identify trends and areas for improvement. You can also use insights from A/B testing to optimise future campaigns.

Key metrics to monitor:

Metrics may vary depending on your email campaign's goals; however, knowing what metrics to examine can make all the difference.

  • Open Rate
    The percentage of recipients who opened the email. Indicates how effective your subject line and timing are.
  • Click-Through Rate (CTR)
    The percentage of recipients who clicked on a link in your email. Measures the effectiveness of your content and CTA.
  • Conversion Rate
    The percentage of recipients who completed the desired action, like purchasing or signing up for a webinar.
  • Bounce Rate
    The percentage of emails that couldn’t be delivered. High bounce rates can hurt your sender reputation.
  • Unsubscribe Rate
    The percentage of recipients who opted out of your email list after receiving the email.

Step 10: Refine and Optimise Future Campaigns

Email marketing is an iterative process, and constant refinement ensures ongoing improvement. In addition to using data from previous email campaigns, you can ideate new strategies, such as new formats and subject lines, for further testing.

Learn from subscriber feedback and behaviour to shape future content. This can help re-engage inactive subscribers.

Types of email campaigns

There are many types of email campaigns. Determining what you'd like to use for your email marketing depends on its relevance to your goals. These are some of the most common email campaigns you can create with and without marketing automation tools.

  • Promotional Emails
    Sent to inform customers about discounts, special offers, or new products.
  • Newsletters
    Regularly sent emails containing company news, updates, and curated content to keep subscribers engaged.
  • Transactional Emails
    Automatically triggered emails like order confirmations, shipping updates, or password resets.
  • Drip Campaigns
    A series of automated emails sent over time to nurture leads or guide users through a sales funnel.
  • Re-engagement Emails
    Designed to reconnect with inactive subscribers or customers, often with special offers or personalised messages.

The 5 C's of email writing

The 5 C's of email writing refer to five essential principles that help ensure clear, professional, and effective communication through email. These principles are widely used in business communication to enhance clarity and encourage the recipient to take appropriate action.

1. Clear

Clearly state the purpose of the email at the beginning and reiterate it, if necessary, at the end. The email should be easy to read and understand. Clarity helps prevent misunderstandings and ensures that the main message is conveyed effectively.

Best Practices:

  • Use simple, direct language that avoids jargon or complex terminology.
  • Focus on one main point or objective per email.
  • Use short sentences and paragraphs to make the email more readable.

2. Concise

Emails should be brief and to the point, containing only the necessary information. Recipients are more likely to read and respond to emails that are concise.

Best Practices:

  • Stick to essential information and avoid overwhelming the recipient with too much content.
  • Use bullet points or numbered lists to organise information and make it easier to digest.

3. Courteous

Politeness and professionalism are key in email communication. Being courteous helps build positive relationships and ensures that your message is well-received.

Best Practices:

  • Use a respectful tone and proper greetings such as “Dear [Name]” or “Hi [Name],” depending on the relationship with the recipient.
  • Include polite language such as “please,” “thank you,” and “kind regards.”
  • Avoid using harsh or overly critical language, even if the email addresses a sensitive issue.

4. Correct

Accuracy is crucial in email writing to maintain professionalism and ensure that your message is taken seriously. This applies to both the content of the email and its structure.

Best Practices:

  • Proofread the email for grammatical errors, spelling mistakes, and punctuation issues.
  • Double-check facts, figures, names, dates, and any other details included in the email.
  • Ensure that attachments, links, or any supporting documents are correct and functional.

5. Complete

Ensure that the email provides all the necessary information for the recipient to take the next steps or understand the context. An incomplete email may lead to confusion or the need for follow-up clarification.

Best Practices:

  • Include all relevant details, such as dates, times, locations, or contact information.
  • If a response is required, clearly state the deadline or next steps expected from the recipient.

Conclusion

Email campaigns are a versatile and powerful tool for engaging customers and driving business growth. By leveraging different types of email campaigns, businesses can build stronger relationships with their audience, enhance brand visibility, and increase conversions.

Tailoring each campaign type to meet specific goals ensures a well-rounded email marketing strategy catering to existing and potential customers. Ultimately, a thoughtful approach to email campaigns helps brands maintain meaningful communication and achieve long-term success.
