What is Email Marketing?

Digital marketing involves many strategies and tools. One of those is email marketing which primarily refers to emailing customers and prospects about your business, its offerings, new promotions, deals, and other value-driven content.

While email marketing may seem a promotional tactic on the surface, it goes deeper than that. It is indeed a communicable tool that builds relationships, fosters growth, warms up leads, and gently turns them into paying customers. Yes, email marketing can make your conversion rate EXPLODE! FOR REAL!!!

Email users have grown to 4+ billion over the years. Plus, email is a more direct and personalized communication channel. You get one-on-one access to your prospects and customers. Yeah, it is virtual, but still direct.

With email marketing you can do a lot: advertise your business, promote existing and new services/ products, inform users about seasonal sales, discounts and offers, engage your customers, make users remember and recall your brand, reinforce customer loyalty and drive sales.

Contrary to a common opinion, email marketing works BIG TIME!

How Does Email Marketing Work?

Email marketing is rooted in lead collection. You collect leads, usually through a lead magnet or a signup form. Once you have some leads, you segment them using filters such as behavior, interests, and needs. Moving on, you create emails to send them specific content at targeted points along their customer lifecycle.

Here’s a step-by-step email marketing process:

• Lead capture: It all starts with grabbing leads. Landing pages, pop-ups and forms are useful to capture leads.
• Segmentation: This involves grouping audiences according to their preferences, demographics and behavior.
• Email automation: It encompasses automating emails keeping the different emotional triggers into account.
• Tracking performance: This involves monitoring the email open rates, conversions and CTR, and conducting A/B tests.
• Email optimization: Optimizing emails is crucial to maximize your efforts. This encompasses testing content formats, send times and subject lines.

Powerful emails sent at peak times to targeted audiences generate unimaginably good results. That explains why emails are 40 times stronger than Twitter or Facebook in converting leads into sales.

Let’s dive into the different types of marketing emails.

What Are the Different Types of Marketing Emails?

61% of all types of consumers prefer it when brands contact them via email as compared to other media. But is every consumer at the exact same stage in their buying journey? No. So a one-size-fits-all strategy will barely work.

This is what led marketers to create different kinds of marketing emails that resonate with different types of audiences. When audiences see something they connect to in their decision-making process, they are highly likely to take action.

Below are the 7 main types of marketing emails along with the different stages they should be used at.

1. Welcome Emails: Just like you warmly greet a visitor, welcome emails have a hospitable tone. They introduce the brand, guide the user, set expectations and initiate a bond.
2. Newsletter emails: Turning prospects into paying customers is a journey. You need to nurture your leads. That happens best when you provide them with updates, tips, blogs, insights and other information through newsletter emails.
3. Transactional emails: Transactional emails inform users about their order status, order confirmation, shipping updates and other concerns including password resets.
4. Promotional emails: Businesses and brands have different promotions from time to time. Promotional emails are time-sensitive emails that share product launches, events, seasonal offers, discounts and other promotions with users.
5. Re-engagement emails: Engaging and re-engaging subscribers is crucial to keep them hooked to your brand. Re-engagement emails help win back all the dormant subscribers and manage the list churn.
6. Feedback or survey emails: Knowing your customers, getting their feedback and collecting insights regarding your brand, different concepts and trends is crucial. This is where survey or feedback emails serve their purpose.
7. Behavioral emails: These are triggered by different user actions such as signup completions, product views and cart abandonment.

Every type of marketing email has a specific role in strengthening relationships with customers. Mastering how and when to use diverse formats dramatically boosts the engagement rates. Not just that, it also reinforces brand loyalty and gradually drives higher conversions. 

The key to get this right? Craft a compelling message and match it to the right point in the customer’s lifecycle. That’s how you make sure your audiences are seen, heard, motivated and valued.

What are the Best Email Marketing Strategies?

Ann Handley, author of Everybody Writers and one of the pioneers of content marketing says,

‘Email is the only place where people — not algorithms — are in control.’

You can best control how your email influences your audiences by devising a powerful strategy mix. Take a look at some of the top email marketing strategies that make the entire process a walk in the park.

Segment Your Audience- Always!

Segment your target audience and then segment it some more. This strategy never fails to work. 

Generic emails honestly cripple your engagement because they don’t make your subscribers feel valued. Effective segmentation can make the email open rate rise by a massive 50% even.

The right way to do it:

• Split your audience first by demographics, primarily their location and age.
• Next, add in the layer of behavioral segmentation. Dissect them using their purchase history.
• Also observe their engagement level, and further segment them.

Strategic audience segmentation helps you create different audience categories ensuring you fulfill their email needs successfully.

Add That Personal Touch

Personalization is the way to go in today’s era. People love it when you customize emails adding that special ‘oomph’ effect to touch a chord with them.

And did you know personalized emails have the power to boost transaction rates by 6 times? Yep, you read that right!

The right way to do it:

• Greet the readers by their names. Instead of Hi, opt for, ‘Hi Rachel’ or ‘Hey Garry.’
• Don’t just stick to greeting your subscribers with the mundane hi. Experiment with different greetings such as ‘Rise and shine sunshine’ or ‘Morning love!’
• Recommend different offerings to subscribers after assessing their past purchases.
• Ensure to send trigger emails such as ‘forgot something’ if someone abandons their cart.

Yes, we know crafting a persuasive email copy is not always a piece of cake. Well, that’s why the world has email copywriters. Get in touch with a seasoned email marketing agency, and they’ll take care of your email copywriting needs.

Optimize Email Subject Lines

The better your email subject lines are, the higher the open rate gets. Personalized subject lines can tend to deliver a 26% better email open rate as compared to the generic, boring ones.

Avoid the dull, dreary, routine subject lines. Instead optimize them.

• Keep them punchy and short. According to Mailchimp, subject lines with 30 to 50 characters (make about 4 to 7 words) have the best open rates.
• Ignite curiosity by using emotionally-connecting and power words such as ‘secret’, ‘free’, ‘like never before’ etc.
• Adding emojis in the subject lines works like a charm. But keep them relevant to the subject.

One more thing: do A/B test different subject lines. This hack can improve the Google Analytics click-through rates by a huge 37%. Pretty awesome, right?

Practice A/B Testing on EVERYTHING

A/B testing is honestly such a savior. When you A/B test different aspects and components of email marketing, you analyze things in detail. Plus, you get a good contrast between what works and what doesn’t.

Knowing what favors you, and what might not be the best fit helps you optimize your email marketing strategy. The results? Higher email open rates, more website traffic, better CTR, and maximized sales.

Just make sure to A/B test the following when conducting email marketing:

• Send times: Test whether early morning, noon, afternoon, evenings, night or late night works for your audience.
• CTA buttons: Find out if the color of the CTA button makes a difference, or whether your audience appreciates ‘get yours’ over ‘buy now’, or the other way around.
• Subject lines: See if your subscribers like the benefit-driven lines, or ones that trigger urgency. Also check if your readers like seeing emojis in the email subject lines.

Well, there are a whole lot of other things you can and must A/B test when doing email marketing. We recommend you consult the entire process with an expert email marketing agency for best results.

What Should You Do Next for Email Marketing?

Now that you know all the basis of email marketing, here’s what you should get started with.

• Discuss email marketing in depth with your marketing team. If you don’t have a separate marketing department yet, analyze your email marketing needs yourself.
• Identify and set your email marketing goals, and align them with your business. An advanced email marketing agency can prove quite helpful in that regard.
• Create a lead magnet. This could be a discount, checklist or a freebie so you can start gathering emails of prospects.
• Pick a suitable email marketing tool for your needs. Again, email marketing consultants can best point you towards an appropriate tool.
• Start with a welcome automation flow so you can welcome and engage your new subscribers.
• Build a detailed email calendar on a monthly basis. Make sure it is packed with valuable content.
• Monitor your email marketing campaigns and optimize them and your email marketing strategy continuously.

It’s 2025 and emails still have their charm. The sooner you get started with email marketing, the better for you.
