Plain text or HTML in cold email?

In this article, we’ll look at plain text vs. HTML, the pros and cons of HTML emails, and help you decide which format to use for your email campaign.

Getting past spam filters and improving your email deliverability is a key criterion when assessing the success of any outreach effort. This logic can also be applied to what may seem like an old-fashioned debate – using HTML or plain text in emails?

Many marketers send plain text emails more often, as they are quite effective, easy to create, load quickly and display correctly in any email client and on any device.

HTML email advantages

Hyperlinks

We often have to redirect the user to some page, such as a product page or our website. For this, html layout is great, which allows you to insert a link into some kind of button or image right in the body of the letter

Design

Well-made HTML emails look attractive and allow companies to convey their corporate identity even to the inbox.

Hierarchy

With the help of HTML-layout it is easier to create a clear hierarchy and highlight important places in the message.

Tracking results

HTML allows you to use mechanisms to track opens and engagement rates – this is important information for optimizing your marketing efforts.

Despite the rather attractive advantages, HTML emails also have quite a few disadvantages and “pain”.

It is believed that developing HTML mailing lists is a very thankless task for a designer and developer. We have to “go back in time”, where tabular templates, inline styles and non-semantic markup were used in the layout.

Disadvantages of HTML emails

There are no standards

While everyone uses HTML and CSS, there are still no standards for how an email client should work. This factor often leads to complex and strange code.

Mail clients

Email programs such as Outlook and Gmail render HTML differently, which in turn leads to the fact that the end user receives a crooked and ugly email.

A large number of hacks

In order for everything to work in different mail programs, you need to provide a lot of points that are important for the correct display of the letter in all of them. This most often leads to the frequent use of workarounds and “dirty hacks”.

No JavaScript

There is no web language in email as a class, because email clients cut out such code for security reasons. Thus, letters are deprived of interactivity.

Inline styles

Most email clients are forced to use inline styles and attributes.

Getting emails into spam

HTML emails are doomed to often end up in the SPAM or Promotions folder. Spam filters and algorithms of email providers are to blame.

Images

A large number of email programs turn off displaying images by default, showing users “broken” emails.

The chance of a response

Most often, HTML emails do not inspire confidence in the user and most likely he will consider your email to be soulless. A potential client will not want to send you a response, as he will consider that this mailing was made by a bot to a large number of emails.

HTML vs plain text emails. When to use what?

Email marketers no longer have to sacrifice deliverability for added visual elements. Hybrid emails allow businesses to balance simple HTML content with the familiar appeal of plain text, and provide spam filters enough data about what’s inside one’s inbox so that important messages don’t get lost in cyberspace – all while adding sophisticated visuals such as colorful calls-to-action buttons or interactive media.

A/B testing is your compass for determining the most successful means of customer communication. Despite their eye-catching appeal, plain text emails offer many advantages over HTML templates–particularly when it comes to business-to-business cold outreach and correspondence with senior personnel.

With the right message tailored to your audience, images in an email can be highly effective. Whether you’re running a retail business, providing branded content or even tracking data – HTML-heavy emails could prove invaluable. 

So, you should already understand how many disadvantages and complexities are associated with HTML emails. Therefore, most marketers and salespeople prefer to use plain text letters, which are as simple as possible to create and save our nerves and time.

It is also worth mentioning that there are quite a few “primitive” users and haters of HTML code in emails, and therefore they simply won’t be able to see your email the way you would like it to be.

Hybrid Format: Combining Plain Text and HTML

In cold email outreach, many marketers try a mixture of plain text and HTML elements in their emails. This combination balances the simplicity of plain text with the aesthetics of HTML. However, is this the right mix for cold emails? Let’s look at the pros and cons of adopting a hybrid format.

Pros:

  1. Visual Appeal. HTML elements like images, buttons, and formatting make emails more attractive and readable. They help grab attention.
  2. Interactive Features. HTML provides interactive elements like CTA buttons or embedded links to encourage subscribers to take actions directly from the email.
  3. Brand Consistency. Using HTML ensures that emails maintain the look and feel of company branding, such as logos, colors, and fonts.
  4. Detailed Analytics. HTML offers metrics like link clicks, email opens, and engagement, providing useful data for future campaigns.

Cons:

  1. Deliverability Issues. HTML-heavy emails are more likely to trigger spam filters, making it harder for emails to reach the recipient. Plain text emails, being simpler, often avoid these filters.

  2. Slower Load Times. Emails with images or complex HTML can take longer to load, frustrating recipients.

  3. Limited Compatibility. Some email clients or devices may not render HTML emails correctly, leading to poor layouts that harm your professional image.

  4. Complexity. Creating hybrid emails requires more time and technical skill than simple plain text emails, which may not be feasible for smaller teams.

While the hybrid format strikes a balance between engagement and simplicity, its use depends on your audience, goals, and resources for cold email campaigns.

Questions to Help You Pick the Right Email Format

  • Are you looking to establish a personal, one-on-one tone? Opt for plain text.
  • Is your goal to visually impress and engage a wide audience? Go for HTML.
  • Do you need a message that loads quickly and works well on any device? Stick with plain text.
  • Concerned about spam filters blocking your email? Plain text is a safer bet.
  • Are you hoping to include eye-catching elements like images or buttons? HTML is the way to go.
  • Who is your target audience? For a formal business setting, plain text may feel more appropriate, while HTML works well for younger, tech-savvy readers.
  • Want to monitor detailed engagement metrics, like link clicks and open rates? HTML will give you those insights.
  • Facing technical issues with HTML formatting? Plain text can ensure your message gets delivered properly.

Why Email Warming is Essential for Cold Emails

While the hybrid format of plain text and HTML offers a compelling mix of personalization and visual appeal, it also brings a common challenge: deliverability.

Conclusion

In the debate between plain text and HTML for cold emails, both formats present their own sets of advantages and challenges. Plain text emails offer authenticity, simplicity, and a higher likelihood of bypassing spam filters, making them ideal for straightforward communication. On the other hand, HTML emails provide visual appeal, interactivity, and branding opportunities, though they come with potential deliverability concerns.

Ultimately, the choice between the two hinges on your specific outreach goals, the preferences of your target audience, and the nature of your message. It’s essential to test and adapt based on feedback, ensuring that your emails not only reach the intended inboxes but also resonate with the recipients.
