Why Marketers Must Optimize Emails for HTML AND Plain Text

 Most email service providers (ESPs) today allow marketers to easily draft visually striking HTML emails using simple WYSIWYG ("What You See Is What You Get") editing tools, making it all too-easy to dismiss traditional, plain text emails as un-important. But if you think plain text emails are a thing of the past, you might want to think again. Plain text still has its place in the email world, so before you completely discredit its importance to your future email marketing sends, keep reading. We'll discuss the importance of drafting emails that render well in both plain text and HTML, as well as our top tips for designing both HTML and plain text versions of your emails.

Why You Shouldn't Ignore Plain Text

Sure, it's tempting to create fancy HTML emails, especially considering you don't need to be a developer these days to do it. But according to email service provider MailChimp, there are five great reasons why you still need to consider plain text.

1) Some Browsers, Email Clients & Mobile Devices Can't Handle HTML

As the infographic reminded us, because of factors like bandwidth and functionality, not all email clients, browsers, and mobile devices that support email are sophisticated enough to display formatting like HTML properly. When marketers fail to optimize their email for both versions, what happens is a broken design and an undecipherable, ineffective email. 

2) Some People Prefer It

Plain and simple. Some people would rather avoid all the bells and whistles and just read the message. While many email clients allow you to make HTML email the default setting, some also enable users to only view emails in plain text. Not solving for this type of email subscriber puts marketers at risk of alienating a portion of their subscriber base.

3) Some Email Types Lend Themselves to Plain Text

Creating HTML emails -- even using simple tools like WYSIWYG editors -- understandably takes more time than creating plain text emails. Because of the extra time and effort it takes a marketer to draft a good-looking HTML email, there are some times when it just isn't worth it. For example, if you send simple, daily email alerts with content such as news feeds or quick links, or if you send email very frequently, plain text is a more efficient way to go.

4) SPAM Filters Like to See Plain Text

When a SPAM filter sees an HTML email without a plain text counterpart, it's more likely to suspect the email to be SPAM, since it's an indication of a "lazy spammer." In other words, failing to include a plain text version of your email is a red flag to SPAM filters.

5) It's Safer for Transactional Messages

When HTML emails include click trackers, it's not uncommon for email clients to warn recipients against "potential privacy threats" or a potential "phishing attempt." Therefore, when sending transactional emails, stick to plain text emails, or you could put yourself at risk of a damaged reputation.

Luckily, most popular email service providers -- including HubSpot's email tool -- enable marketers to edit and customize both the HTML and plain text versions of their emails, making it unnecessary to completely give up the visually appealing benefits of HTML emails for the sake of plain text.

And even if your email service provider doesn't require you to create a plain text version when designing an HTML email, it's a best practice to create a plain text version regardless, for all of the reasons we just mentioned above. When you optimize both HTML and plain text versions of your email, you ensure that anyone can read it, regardless of their default settings, email client, browser, or mobile device's capabilities. That being said, there are still a few things you should keep in mind when creating each version of your emails.

Tips for Designing HTML Versions of Email 

1) Assign Clear Alt Text to Images

As we saw with the Groupon example above, even if your recipients' email client does support some HTML formatting, it may not always take kindly to images in email. Try to avoid image-heavy emails, and when you do include images, be sure to tag the image with alt text that clearly denotes what the image is. It's not uncommon for the alt text to show up in place of the image, and when this is the case, it's helpful to give recipients an idea of what the image was supposed to portray.

2) Make Sure Email is Comprehensive Without Images

To piggy-back off our last tip, avoid using images to display important information. As a general rule of thumb, think about how your email would look if the images didn't display. Would your recipients be able to obtain the same information as they would have if the images did display? If not, re-think your email. If you include a call-to-action (CTA) image button as we did in the HubSpot example earlier in this post, include a text-based CTA in the post as well. Failing to do so will mean you'll take a hit in the traffic and/or leads you were hoping to generate from the image CTAs in your email if they fail to render.

3) Avoid CSS in Emails

CSS, or Cascading Style Sheets, is a type of coding language that is more complicated than HTML. Because not all email clients/browsers accept the same codes, and because email doesn't tend to be as sophisticated as a web browser, including CSS in email tends to be a recipe for rendering disaster. For more information about how different email clients support CSS, see this overview from CampaignMonitor.

4) Use Plain Text-Style Bullets

In addition to images, another element that tends to break in HTML email renderings are HTML-style bullets.

You know, those nice-looking
rounded or square bullets
that look like this?
So rather than running the risk of invisible or wonky bullets, use a plain text alternative such as asterisks (*) or dashes (—) that are more likely to show up no matter what.

5) Don't Copy & Paste Text From Other Word Processors

Oh, the formatting horror! Raise your hand if you've ever suffered the frustration of copying and pasting text from a Word document into your ESP. I know mine is raised. Doing so carries over formatting from within the word processor, and funks up the text within your ESP. Your safest bet is to start from scratch and craft copy directly within your ESP.

6) Be Wary of Dark Background Colors

While blocks of color can add a pretty design element to your email, be careful. Say you decided to create your entire email -- or just a section -- with a dark gray background. To make the text readable, you selected white as your font color. Now what happens when your recipient's email client doesn't render that background color? Invisible text! Lesson: the visibility of your email's copy should never depend on the background color of your email.

7) Always Include a Link to the Web Version

Many ESPs will enable you to create a web-based version of your email. Include this link in your email send. That way, if the images or anything else isn't rendering properly for your recipients, they can easily click over to the web-based version and see exactly what you intended.
