What is Email Marketing?

Email marketing is when you send targeted messages and promotional content to new or future customers by email. It is a powerful digital marketing strategy that allows businesses to communicate directly with their audience, build strong relationships with customers, nurture leads, and sell their products and services.

Here’s what email marketing often looks like for different business types:

  • For eCommerce businesses, email marketing lets you sell products, recover abandoned carts, and increase lifetime value.
  • Small business owners can use email marketing to maintain brand awareness and build relationships over time.
  • For SaaS companies, email marketing is an ideal channel for generating leads and converting leads or free trial users into new customers.
  • Bloggers and publishers use email marketing to drive traffic to their websites and affiliate links, which means more revenue.
  • Enterprise clients can scale their email marketing plan to reach thousands or even millions of customers at once.

Before we get too far into the details and strategies, let’s go over some basic email marketing terms you should know.

Email Marketing Glossary

Email Marketing Glossary and Definitions

Like all digital marketing channels, email marketing has its own “language.” Many of the terms sound like what they are. But we still want to give you clear definitions of each idea. That way you’ll understand the more intermediate and advanced email marketing concepts later in this guide.

  • Email: An electronic message that you can send to people over the internet.
  • Campaign: A single marketing email sent to promote a product, event, or brand. Sometimes refers to a series of related emails sent over a specific period of time to achieve a particular goal.
  • Subscriber: A person who signs up or gives permission to receive emails from a particular business or organization.
  • Newsletter: A regular email sent to subscribers sharing news, and updates about a specific topic or business. Sometimes known as a broadcast.
  • Automation: a series of pre-written emails that go out automatically in response to a subscriber’s actions. For example, as when a customer abandons their cart without purchasing, they might get a series of emails reminding them about their items. Also known as email sequence or autoresponder
  • Email List: A collection of email addresses that a business or organization has gathered from people who want to receive their emails.
  • Opt in (verb): To choose to receive marketing emails from a person or business. Also known as subscribing, signing up, or joining an email list. Sometimes spelled opt-in.
  • Optin (noun): An incentive for people to subscribe to your list. Also called a lead magnet.
  • Lead Magnet: A free resource that attracts people to subscribe to your email list. Examples include checklists, printables, gated content for subscribers only, or exclusive reports.
  • Optin Form: a signup form where visitors can join your email list. Optin forms can be of different types: popup forms, inline forms, fullscreen squeeze pages, sliders, floating optin bars, and more
  • Subject Line: A short line of text that appears in the subscriber’s inbox and gives a brief summary or hints about what an email is about.
  • Open Rate: The percentage of people who open and read an email out of the total number of people who received it.
  • Click-through Rate: The percentage of people who click on a link in an email to visit a website or webpage.
  • Conversion: When someone takes a desired action after receiving an email, such as buying something, signing up for a service, or filling out a form.
  • Unsubscribe: To remove yourself from an email list and stop receiving emails from a particular sender.
  • Personalization: Customizing an email with the recipient’s name or other relevant information to make it feel more personal and engaging.
  • Segmentation: Automatically placing subscribers into groups based on their activity, such as signup date, timezone, sale history, and other factors.
  • Landing Page: A web page that people are directed to when they click on a link in an email. It usually contains more information or offers related to the email’s content.
  • Mobile Optimization: Making sure that emails have the design and formatting to display properly on smartphones and tablets.
  • Spam: Unwanted or unsolicited emails that are often sent in bulk. You don’t want your marketing emails to go to spam.
  • Call-to-Action: A clear and direct message or button in an email that encourages the recipient to take a specific action, such as “Buy Now” or “Sign Up.” Often abbreviated CTA.

We’ll go over many of these concepts in greater detail throughout this article. Now that you understand the basic vocabulary, let’s go over some of the advantages and disadvantages of email marketing.

What Are the Advantages of Email Marketing?

There are many benefits of email marketing. Here are our top reasons why email marketing is so effective:

Email Marketing Statistics

We wanted to share just a few other email marketing statistics to show the advantages of email marketing even more.

While the case for email is strong, there are a few downsides. We want to make sure you have a full understanding of email marketing, so we’ll go over these disadvantages next.

What Are the Disadvantages of Email Marketing?

No marketing channel is perfect. Email marketing does have a few disadvantages that we want you to be aware of:

  • Email is a consent-based channel. You can’t pay your way in front of people.
  • Keeping your emails out of spam filters and staying compliant with email-related legislation in your area can be complicated.
  • Small technical mistakes can tank email deliverability and hamper your marketing efforts.
  • Email marketing can be very competitive. Because it works so well, everyone wants to do it!
  • Most email service providers (ESPs) aren’t free and pricing often increases as your email list grows.

However, these disadvantages can actually become advantages.

The required optin process can make email more effective. Subscribers are actively choosing to receive marketing emails from your business. That means they’re more likely to engage with your email content. It’s the difference between chasing someone down to talk to them, and someone initiating a conversation with you on their own.

The competitive landscape and cost of email marketing mean you need to be thoughtful about your email marketing strategy. This will actually benefit your customers and, therefore, your business.

How to Do Email Marketing Successfully: A 5-Step Guide

Now that we’ve gone over the basics, we’d like to share a step-by-step guide to email marketing so you know exactly what to do.

To successfully get started with email marketing, you need to do 5 things:

  1. Define Your Goals
  2. Choose an Email Service Provider
  3. Create an Optin Form to Build Your Email List
  4. Set Up Marketing Emails
  5. Track Email Marketing Metrics

Let’s get started!

1. Define Your Goals

Before you spend money on an email marketing tool or type out that first email, you must identify your goals. Email marketing isn’t just something to do because we say so. You need to figure out what you want to achieve.

An easy way to think about this question is: What do you want to sell through email? In other words, how do you plan to earn money with email marketing?

For example, if you’re an online store or service provider, you want to sell products and services to your email marketing list.

For bloggers and content creators, what you’re selling is content. You might charge readers directly for content, as in a membership site, or sell advertising and affiliate links. You can use email marketing to drive traffic back to your blog.

You also need to consider what your audience wants. Ask yourself:

  • What will convince them to join your list? This can help you come up with attractive lead magnet ideas.
  • What will convince them to stay on your list? Knowing this can help you decide what kind of content to send to your email subscribers.
  • What will convince them to buy what you’re selling? These are the offers and promotions you include in your marketing emails.

With these goals in mind, you can now choose tools to use for your email marketing strategy.

2. Choose an Email Service Provider

The first thing you need is an email service provider (ESP). An ESP will provide the tools you need to create, send, and manage email campaigns to your audience.

4. Set Up Marketing Emails

Whichever email service provider you choose should have an email builder you can use to easily create your emails. Let’s go over the basic parts of a successful email marketing campaign, along with some resources to help you write your own.

Subject Line

email subject line anatomy

This text appears in your subscriber’s inbox and should give them a hint or reason to open the email.

Preheader Text

This text sometimes appears next to the subject line in the user’s inbox. This is another opportunity to persuade your reader to open your message.


branded templates

You can put all kinds of content in your emails:

  • Text
  • Headings and subheadings
  • Lists
  • Images
  • Links
  • Buttons

Whatever you send, make sure it’s concise, engaging, and relevant to your audience. Even if you don’t have something specific to sell in a particular email, focus on providing value to your recipients. Do this by addressing their pain points and highlighting the benefits of your products or services.

Here are some of the best eCommerce email examples and welcome email examples to give you some ideas.

Call to Action (CTA)

Call to action button HTML email-min

Every email should have a purpose. What do you want subscribers to do after they read your email? Invite them to take this action!

Some common CTAs include:

  • Make a purchase
  • Download a freebie
  • Read a blog post
  • Follow your brand on social media
  • Forward this email to a friend

Subscription Management

visible unsubscribe button

At the bottom of every email, you should have a link to unsubscribe. That may seem counterintuitive, but email marketing is a consent-based channel. It’s better to let uninterested subscribers leave your list than risk them sending your emails to the spam folder.

One way to reduce your unsubscribe rate is to also include a link where people can manage their own subscriptions. Giving them a way to opt out of certain topics or hear from you less often shows that you care about their experience.

Delivery Options

email delivery options

You can set a specific date and time to send a one-time email or emails in an autoresponder series. Think about the time zone and preferences of your target audience. This can help you maximize engagement.

While there are lots of ways to optimize your marketing emails, we encourage you not to overthink too hard. Email marketing is a long game, and how you show up consistently over time is more important than writing a single perfect email.

This brings us to the last step in our guide: monitoring your progress.

5. Track Email Marketing Metrics

tracking email marketing statistics

After sending your email, track and analyze key email metrics such as:

  • Open rate: how many subscribers opened the email
  • Click-through rates: how many subscribers clicked links in the email
  • Conversion rate: how many subscribers made a purchase, filled out a form, or did some other conversion you want to track
  • Unsubscribe rates: how many subscribers unsubscribed from an email
  • Deliverability rate: how many subscribers received your email in their main inbox

Use this data to refine your future email campaigns and optimize your strategies.

We also recommend that you regularly clean your email list. Removing invalid or inactive email addresses improves deliverability. Keeping your list clean also ensures that you’re targeting an engaged audience.

Now that you know how to do email marketing, let’s take a look at some common challenges you might face and how to overcome them.

5 Biggest Email Marketing Challenges (And How to Solve Them)

Effective email marketing is relatively simple, but that doesn’t mean it’s easy. There are a lot of different factors involved and, unfortunately, writing good emails isn’t always enough.

We have a full list of email marketing best practices you can read for more detail. Here are some of the most common challenges our customers have encountered, along with proven solutions.

1. How to Build an Email List

brian tracey signup form example

The first challenge is needing people to send emails to in the first place. Fortunately, this is perhaps the easiest problem to solve!

Even if you have no subscribers, you can build an email list from scratch with email signup forms on your website.

Solution: To get more signups, make sure that visitors clearly understand the benefits of joining your list.

For more ideas, check out our top list-building tools and ways to build your email list for free.

2. How to Ensure Email Deliverability

email deliverability issues

Once you have enough people to send email to, the most common next challenge is making sure the emails you’re sending actually land in their inbox. Average deliverability rates hover around 81%, which means up to 20% of your emails may never even make it to your subscriber’s email client!

Solution: Follow email deliverability best practices to make sure your emails make it into the right inbox.

  • Avoid spammy words that can trigger spam filters. These might include words like “click,” “free,” “trial,” “cost,” “cheap,” “prize,” or unusual capitalization and punctuation.
  • Clean your email list regularly to remove inactive subscribers.
  • Segment your emails appropriately so that subscribers get content they actually care about.
  • Provide ways for users to manage their own subscriptions instead of unsubscribing or reporting as spam.

3. How to Improve Email Open Rates

email open rates

The average open rate for emails is around 21%. If yours are below that, you may be wondering, “Why aren’t people opening my emails?” There are many reasons that aren’t under your control, but plenty of ways that you can improve your email open rates.

Solution: Write and send high-quality emails. Everything from the email subject line to the email template design should be a valuable, pleasant experience for subscribers. If you can convince them to open one email, they’ll be more likely to open future emails.

  • Make your subject line exciting and informative enough for people to click on. Try to balance being clear with having a bit of mystery.
  • Keep your subject line length short and easy to understand.
  • Use preview text to provide extra insight into what’s in your email content.
  • Improve your email copy by thinking back to your goal-setting. What information, skills, or products do your customers need to solve their problems? Deliver content that helps address those issues.
  • Optimize your email design, especially for mobile devices. Use visuals wisely and make sure they show up well on different screen sizes. You can also make mobile optins that show up well on smaller device sizes.

4. How to Boost Email Conversion Rates

email conversion rates by email types

Let’s say you’re getting a healthy number of signups. Subscribers are receiving and opening your emails. But no one is clicking or buying.

You aren’t alone. The average email conversion rate in a study by Klaviyo ranged from just 0.1% to over 3%.

Solution: Improve your conversion rates by tuning into what your audience needs and wants.

  • List segmentation means dividing your list into different groups. You can then send each group more targeted messaging that should improve your conversion rates. Learn about different ways to segment your email list and see what works best for your business.
  • Personalized email content goes beyond saying, “Hey, FIRST NAME!” You could send product recommendations based on past purchases. Other personalization techniques include sending location-specific offers or content based on demographics. When subscribers receive personalized emails, customer loyalty is likely to increase.
  • A/B testing your email newsletters can help you find the most effective subject lines, content, email templates, and CTAs. Many email service providers have split testing functionality built in.

5. How to Scale Your Email Marketing Efforts

drip automation

What if your email marketing strategy is working pretty well, but takes more time than you have?

Creating personalized content for a few segments is one thing. But as you add more subscribers, offers, and promotions, your email marketing will get more complex. Fortunately, we have strategies and resources to help you scale.

Solution: Work smarter, not harder. Build on what already works in your own email marketing or strategies that others have proven.

And of course, you can use any of OptinMonster’s signup form templates to scale your email marketing quickly.
