Email marketing is an incredibly useful tool for any business looking to grow their sales leads and gain new customers. In 2022, each email generated $36 per $1 spent, with the best email marketing strategies and tools, you too can reach this high return on investment.
Your Guide to a Successful Email Campaign:
Finding your user base
Your initial investment in an email marketing database is possibly the most important area to get right. This is where the majority of the spending for email marketing goes, so a good quality database relevant to your target user base is essential.
A reliable database of user information and email hosting site setup is an invaluable tool that prevents your emails and by extension, your website, from being marked as spam. Your site reputation is linked to all connected activity, including email delivery. Therefore, if your database has a high level of subscriber decay (see below), these delivery issues and high bounce rates may lead your website to be marked as spam- impacting your overall online presence.
In addition to providing a quality email database, a common work around for this issue is to set up an alternative domain for your campaign emails. If the email account and website address do not share the same address the reputation impacts of an unsuccessful campaign will not negatively effect your main website domain.
HTML or Plain Text?
This debate is a much-talked-about topic in the email marketing world. What is lost in terms of style and impact when a plain text email is used instead of HTML? How can plain text benefit your bounce rates whereas HTML can be more likely to be marked as spam?
HTML is a coding method used in email marketing to create a multimedia message with images, video, colour, and other branding and style. This is commonly used in Business-to-Consumer (B2C) marketing to make a big impact with a snappy and eye-catching message and demonstration of products by including images. A picture paints a thousand words. With a distinct and clear visual HTML email your business can promote itself without lengthy ad copy that may be read by a limited number of customers.
However, the extra coding used in HTML emails can cause problems on the technical end by preventing your email from properly rendering or even sending emails. Google’s Gmail email client disables many HTML features, and mobiles often have more trouble rendering and spacing HTML elements.
Using a plain text email, you can get a basic message across without facing these difficulties.
Although you do lose the style afforded by HTML, plain text uses ASCII coding with a stripped-down number of options that require you to reconsider and think more carefully about the actual text and message of your email. Without attention-grabbing images, your marketing message itself is made the focus of the email, which is a better way to gain Business-to-Business (B2B) customers who appreciate a straightforward message that clearly presents what your business has to offer.
Long or very Short Text?
The sooner you make your point the better in marketing. Long-text emails with a lot of non-relevant information are unlikely to get read by many recipients. If you need to include a lot of detail to explain a more complex or specific service in your email, make sure to clearly introduce the key message at the start of the email, emphasizing the right information before contextualizing your offer where required.
When writing ad copy, short sentences and paragraphs are key for emphasis and improved reader retention. However, emails less than 50 words can have minimal impact, the ideal length being between 50-200 words- no more than the number of words under this subheading. You need to provide a good amount of relevant information to promote your business or offer and explain clearly the benefits.
Reaching the right balance between concise emails and providing information for your audience can be a process of trial and error, but finding which approach works best for your business is important to begin to see success in your email campaign.
How many Emails Should I Send to Follow-Up?
Timing is vitally important to the success of a marketing email. Sending too many emails in a short amount of time can make your business seem too pushy or get blocked as spam. However, sending just 1 introductory email and not following up soon enough can limit the visibility and sticking power of your message for potential customers.
The average campaign is around 3 emails long, with an introductory email, a reminder, and a final email. Each of these should include the option to unsubscribe from your email list. This not only gives the recipients the option to remove irrelevant emails from their inboxes, but also helps you target future campaigns and follow-ups to users who are more likely to respond positively to your emails.
Each campaign should be planned carefully to be appropriate to the targeted users and the purpose of your campaign. If your email is about a limited-time discount or offer, more emails in faster succession may be beneficial, market research finds that 33% of marketers send an email each week.
However, if you are reaching out in a B2B capacity, providing a non-intrusive campaign of 3 emails spaced throughout a number of weeks may be preferable and forms a more professional relationship with your recipients.
Email data is a priority source of information on the success of your marketing strategy as a whole and the ways in which your approach and messaging are successful. Unlike social media marketing or SEO, there are minimal external impacts, updates, or changes that occur over time, so comparing your metrics over time is a much simpler job.
You can use this data to hone your email marketing strategy and discover the email marketing best practices that work for your business. The best email marketing ideas can come from the failures of previous campaigns or from comparing similar campaigns run in parallel as an A/B test.
Tweaking the length, regularity, timing, or even coding style of different campaigns with a similar message and sending these to similar audience groups provides a lot of useful data when you study and compare email marketing metrics that are important to your goals.
Email Marketing Metrics to track
For a successful lead-acquisition direct email marketing campaign, the most important metrics to track are the Open Rate, Click-Through Rate (CTR) and Conversion Rate.
This is the most straightforward way to measure the success of your campaign, but not necessarily the best indication of a successful lead-acquisition email. In 2023, the average open rate for email marketing was only 38.3%, but using our smart email marketing strategies you can get your campaign above the average. You should aim for this open rate as a benchmark for a successful campaign, but a higher rate can be achieved with an eye-catching, interesting subject line and preview text.
Using numbers, like customer satisfaction rates, savings possible through your deal, or a relevant statistic in the text they see directly in their inbox or notifications is a great way to attract initial interest. Choosing a unique subject for the email can help you stand out in your recipient’s inbox and make a first impression that encourages potential customers to interact further with your marketing.
For a mobile-friendly email campaign, the preview text is an easy way to add extra context to your subject line on the first interaction with the email. Unlike on desktop, mobile inboxes don’t automatically display the entire email alongside the subject line. A quality preview text provides more characters to get your point across, seen to improve open rates by 7%. However, this feature is only available in HTML email formats so the decision is going to be different for each business and campaign.
A high CTR is a sign that your Call to Action (CTA) is successful in bringing traffic to your site. Each time a user is interested in what you have to offer and clicks a link to your site to learn more, you gain traffic and potentially a new customer.
The email copy should reflect your business’s unique selling points, offers, or products in a straightforward way. Avoiding overly flowery language or promoting your business too much before getting to the main point can decrease the CTR of your email campaign, especially for B2B campaigns read by recipients with limited time to read through your email.

Despite being a reflection of your website’s content success and user retention quality of your landing page rather than the email itself, the conversion rate is just as important as any other metric- perhaps even more.
A low conversion rate indicates that the quality of your offer or the tone of your email doesn’t accurately reflect the service you present on your website. Although it may be tempting to exaggerate your success rates or overinflate the quality of the content of your services when looking to gain leads, this is not a successful long-term strategy.
Your emails will only gain conversions by accurately and honestly marketing what you offer, your business’s approach, and your purpose. If a user comes to your site looking or hoping for something different from what they can actually get, you will not gain a long-term customer from your lead generation campaign.
Conversion rate optimisation is key to developing a long-term and successful customer acquisition strategy from any form of marketing. Email marketing is a method that has a higher return on investment as the direct method is targeted at the most relevant audience and guiding them successfully towards the conversion point with only a few interactions.
Some other key metrics to track include:
- Bounce Rate- This is the ratio of successful deliveries to a target’s inbox to failures due to being marked as spam, or a vacant or invalid email. A rate of over 40% suggests an issue with the relevance and ROI of your email database and you need to audit your email subscriber list.
- Subscriber decay- Over time a database of emails loses its usefulness, with 22.5% of emails becoming vacant or invalid each year on average. A high-quality database that updates and is audited regularly by your email database provider or hosting service is key to avoiding spending money sending emails that will automatically bounce.
- Number of Opens per User- if a campaign has a low open rate, you can still find value from the customers you do reach. If a single recipient opens or shares your email multiple times, they may be seriously considering your offer and comparing it with others, a sign they are further along in the sales funnel. Sending a follow-up email with a personalised message or offer could be the next step to gaining a valuable customer.
