Why Are They Important?
The version of an email that recipients receive, whether HTML or plain text, depends on various factors such as their email client settings, device capabilities and personal preferences.
In general, modern email clients and devices support HTML emails and are capable of rendering them properly. As a result, the majority of recipients are likely to receive and view the HTML version of your email. HTML emails allow for more visually appealing designs, including images, formatting and interactive elements, which can enhance the overall user experience.
There are scenarios where recipients may receive the plain text version instead and these are explained in more detail further down. However, a key reason for savvy marketers to generate a plain text version alongside the HTML email is to avoid spam filters. Why is this crucial? When it comes to email deliverability, avoiding spam filters is essential to ensure your messages reach the intended recipients' inboxes. Sending multipart emails can significantly contribute to achieving this goal.
Avoiding Spam Filters
Spam filters often scrutinise emails for various characteristics that might indicate spam or malicious content. One such characteristic is the excessive use of HTML elements in an email. By sending only an HTML version, your email might trigger spam filters and end up in the recipients' spam or junk folders.
On the other hand, including a plain text version alongside the HTML version helps to establish legitimacy and transparency. Multipart emails demonstrate that your message is not solely focused on visual aesthetics but also provides valuable content in a plain, straightforward format.
In addition, plain text versions of emails have a simpler structure, making it easier for spam filters to analyse and verify the content. By offering both HTML and plain text versions, you increase the chances of your email bypassing spam filters and reaching the primary inbox of your recipients.
