 How to Choose Between Plain Text Email and HTML Email?


In the dynamic landscape of digital communication, the choice between plain text and HTML emails has become a pivotal decision for businesses striving to connect authentically with their audience. Most email marketers prefer sending plain text emails because of quick loading times, simplicity in creating them, efficiency, and identical appearance across a range of email clients and devices. We will discuss the benefits and drawbacks of sending HTML emails in this blog. Also, we can look at when to use HTML and plain text for your cold outreach emails.

Finding the Right Tone

Plain text emails, reminiscent of personal correspondence, often resonate with sincerity and authenticity. They foster a direct connection, ideal for one-on-one communication and scenarios where a personal touch is paramount. On the flip side, HTML emails offer a canvas for creativity, allowing you to visually showcase your brand, integrate multimedia elements, and craft visually appealing messages tailored for marketing campaigns and brand promotion.

Navigating Deliverability Challenges

Ensuring your emails land in the coveted inbox rather than the dreaded spam folder is a perpetual challenge. Plain text emails, with their simplicity and straightforward nature, tend to navigate spam filters more smoothly, contributing to higher deliverability rates. Conversely, HTML emails, while visually compelling, require strategic design to avoid triggering spam filters and ensure widespread reach.

Which Is Better for Cold Email Outreach: Plain Text or HTML?

The effectiveness of plain text versus HTML formatting for cold email outreach depends on various factors, including your target audience, the nature of your message, and your overall email marketing strategy. Here are some considerations for both plain text and HTML formatting:

Plain Text

  • Personal Touch
    Plain text emails can feel more personal and direct. They mimic the style of one-to-one communication and can create a sense of authenticity.
  • Deliverability
    Plain text emails are less likely to trigger spam filters, as they often resemble typical personal or business correspondence. This can result in better deliverability rates.
  • Mobile Compatibility
    Plain text emails are generally more mobile-friendly, as they are less likely to have formatting issues on different devices.
  • Speed and Simplicity
    Creating plain text emails is often quicker and requires less effort than designing HTML emails. They can be more straightforward and to the point.


  • Visual Appeal

    HTML emails allow for more creative and visually appealing designs. You can include images, logos, and formatted text to make your emails stand out.

  • Branding

    HTML emails provide an opportunity to reinforce your brand through the consistent use of colors, fonts, and logos. This can help with brand recognition.

  • Links and CTAs

  • Tracking and Analytics

  • Audience Preference

    consider your target audience’s preferences. Some people may prefer the simplicity of plain text, while others may respond better to visually appealing HTML emails.

  • Objective of the Email

    The purpose of your email campaign may influence your formatting choice. If you’re conveying a personal message or seeking a one-on-one conversation, plain text might be more appropriate. For promotional or marketing emails, HTML formatting could be more effective.

    A/B testing can help determine which format works best for your specific audience and goals. Test variations of plain text and HTML emails to see which yields better results.

    There is no one-size-fits-all answer. The most effective approach may involve testing and adapting based on your specific circumstances. Additionally, be mindful of privacy regulations and ensure your emails comply with relevant laws, such as the General Data Protection Regulation (GDPR) or the CAN-SPAM Act.

Some recipients may disable the loading of external content for security reasons.HTML emails offer a range of design and functionality advantages, but they come with challenges such as rendering issues, potential spam filtering, and accessibility concerns. Careful testing and consideration of your audience’s preferences and technical constraints are essential to creating effective HTML email campaigns.

When Should I Use Emails in HTML vs. Plain Text

Whether to use HTML versus plain text emails relies on a number of things, such as your target audience, the type of communication you’re sending, and your own objectives. You can use the following guidelines to choose which format to use :

Use HTML Emails When

  • Visual Appeal is Important

    If your message benefits from visual elements such as images, logos, and formatted text, or if you want to create a more visually engaging and branded experience, HTML emails are a good choice.

  • Branding and Marketing

    For promotional emails, newsletters, or marketing campaigns, HTML allows for creative and branded designs that can capture the recipient’s attention and reinforce your brand identity.

  • Interactive Elements Are Needed

    If your email includes interactive elements like clickable buttons, hyperlinks, or calls-to-action (CTAs), HTML is necessary for incorporating these features.

  • Tracking and Analytics Are Essential

    If you rely on detailed tracking and analytics to measure the success of your email campaigns, HTML emails provide more robust capabilities for monitoring open rates, click-through rates, and other metrics.

  • Multimedia Integration

    If you want to include multimedia elements such as images, videos, or audio to enhance your message, HTML is the preferred format.

Use Plain Text Emails When

  • Personalization and Authenticity

    For one-on-one communication or when a more personal and authentic touch is crucial, plain text emails can be effective. They resemble personal emails and may feel more genuine.

  • Higher Deliverability

    Plain text emails are less likely to trigger spam filters and may have higher deliverability rates. This is particularly important if reaching the recipient’s inbox is a top priority.

  • Mobile-Friendly Communication
    Plain text emails tend to be more mobile-friendly, as they are less likely to have formatting issues on different devices. If your audience primarily accesses emails on mobile devices, plain text can be a good choice.
  • Simplicity and Speed

    When you need to send a quick and straightforward message without the need for elaborate formatting, HTML’s complexity can be unnecessary. Plain text is faster to create and can be more direct.

  • Compliance and Accessibility

    Plain text emails are generally more accessible and comply better with accessibility standards. If you have concerns about reaching a diverse audience, plain text may be a safer option.

    In many cases, a combination of both HTML and plain text emails may be suitable. Some email marketing platforms allow you to send multipart emails, where the recipient’s email client displays either the HTML or plain text version based on their preferences or capabilities. This approach ensures a better user experience for a wider range of recipients.


In the ever-evolving landscape of email communication, the choice between plain text vs HTML formatting has proven to be a nuanced decision, shaping the effectiveness of outreach strategies for businesses and marketers alike. As we conclude our exploration into this pivotal topic, armed with insights from our journey through the realms of personalization, deliverability, and engagement, it becomes evident that the key lies in striking a harmonious balance between the simplicity of plain text and the sophistication of HTML.

Embracing Authenticity

Plain text emails, with their unadorned simplicity, resonate as authentic and direct. They mimic the natural flow of personal correspondence, fostering a sense of trust and connection between the sender and the recipient. In an era where genuine engagement is paramount, the humble plain text email emerges as a powerful tool for building relationships and establishing meaningful connections.

Unleashing Visual Impact

On the other end of the spectrum, HTML emails open the door to a world of visual storytelling and brand representation. With the ability to integrate multimedia elements, employ striking visuals, and showcase brand aesthetics, HTML emails excel in capturing attention and conveying messages with a creative flair. They serve as the canvas upon which brands can paint a vivid picture of their identity.
