A Beginner's Guide to Building HTML Emails from Scratch

By Fathima - September 04, 2024

Welcome to your first step into the world of HTML email! If you've ever wanted to create beautiful, responsive emails that look great on any device, you're in the right place. This blog will walk you through the basics of building an HTML email from scratch, with coding examples to help you along the way. Don't worry if you're new to this—I'll be right here with you, explaining each step in plain English.

Why HTML Emails?

Before we dive into the code, let's quickly touch on why HTML emails are so important. Unlike plain text emails, HTML emails allow you to include images, links, and styled text. This makes your emails more engaging and visually appealing, which is crucial for marketing campaigns, newsletters, or any professional communication.

Getting Started: The Basics

1. Basic HTML Structure

Every HTML email starts with a basic structure.

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Your Email Title</title>
</head>
<body>
  <!-- Your email content goes here -->
</body>
</html>

Breakdown of the above code

<!DOCTYPE>: Tells the email client that this is an HTML document.
<html> and <body>: These tags wrap around the content of your email.
meta tags: These help ensure your email is mobile-friendly. The <viewport> tag is especially important for responsive design, making sure your email scales correctly on different devices.

2. Adding Content to Your Email

Now, let's add some content. We'll start with a simple header, a paragraph, and a link.

<body>
  <h1 style="text-align:center;">Welcome to Our Newsletter!</h1>
  <p style="font-size:16px; line-height:1.5;">
    We're excited to share our latest updates with you. Check out our 
    <a href="https://example.com" style="color:#1a73e8; text-decoration:none;">latest blog post</a>.
  </p>
</body>

Breakdown of the above code

<h1>: This is your main heading. The style attribute is used to center the text.
<p>: This is a paragraph of text. Notice how we style it to make it easy to read.
<a>: This is a link. The href attribute is where you put the URL you want to link to.

3. Inline CSS: Styling Your Email

Unlike web pages, HTML emails require you to use inline CSS for styling. This means all your styles need to be applied directly to each element.

For example, if you want to add a background color and padding to your email, you'd do it like this:

<body style="background-color:#f4f4f4; padding:20px;">
  <!-- Email content -->
</body>

Why Inline CSS?

Most email clients strip out <style> tags from the <head>, so inline CSS is the safest way to ensure your styles are applied.

Building a Simple Email Layout

Now that you know the basics, let's build a simple email layout with a header, a main content area, and a footer.

<body style="background-color:#f4f4f4; padding:20px;">
  <table width="100%" border="0" cellspacing="0" cellpadding="0">
    <tr>
      <td style="background-color:#ffffff; padding:20px;">
        <!-- Header -->
        <h1 style="color:#333333; text-align:center;">Welcome!</h1>

        <!-- Main Content -->
        <p style="font-size:16px; color:#666666; line-height:1.5;">
          Thank you for subscribing to our newsletter. We're glad to have you on board!
        </p>
        <p style="font-size:16px; color:#666666; line-height:1.5;">
          Stay tuned for the latest news and updates from our team.
        </p>

        <!-- Footer -->
        <p style="font-size:12px; color:#999999; text-align:center;">
          &copy; 2024 Your Company Name. All rights reserved.
        </p>
      </td>
    </tr>
  </table>
</body>

Breakdown of the above code

<table>: We use tables to structure the layout of the email. This is a tried-and-true method for ensuring consistent rendering across different email clients.
<td>: This is a table cell where we put all our content. The style attribute is used to add padding and background color.
Header, Content, Footer: We've separated the content into sections for clarity.

Testing Your HTML Email

Before you send your email to anyone, you'll want to test it. Here are a few ways to do that:

Send it to yourself: The simplest way to see how your email looks is to send it to your own email address.
Use an email testing tool: Services like Litmus or Email on Acid let you preview how your email will look in different email clients.
Check the mobile view: Since a large percentage of emails are opened on mobile devices, make sure your email looks great on small screens too.
