Learn how to send a simple text-only email in Klaviyo. Text-only emails can contain limited formatting and images, but are generally much simpler in style and structure than HTML emails (e.g., those built in Klaviyo’s drag-and-drop editor).

This article refers to emails that consist mainly or entirely of text. Learn how to customize the plain-text version of an HTML email to improve the deliverability and accessibility of emails you build in the drag-and-drop editor.

About text-only emails

Text-only emails are a great option if you want your message to have a very personal feel. These emails can look similar to a message you send from your personal inbox, and generally contain less branded content and design elements than a standard HTML email.

A text-only email can be a good option for:

  • A message in a welcome series
    You can include a text-only email as a message in your welcome flow with a personal note about how your company got started or what sets you apart from other brands.
  • Apology emails
    When your company has made a mistake and needs to notify your customers about it, consider sending a text-only email.
  • Text-heavy messages
    If you’re sending a long email that is mostly or entirely text, a text-only email will be easier for screen readers, smart watches, and other assistive technology to read.

Text-only emails are often most impactful when signed by a member of your team (e.g., your founder/CEO). While they aren’t right for every use case, text-only emails often see higher click rates than fully designed HTML emails.

Note that you can add personalization (e.g., a first name variable), include images, change font styles and colors, add bullet points or numbered lists, and use other limited styling options.

  1. Optional: to include an image, place your cursor where you want it, then click Add image in the toolbar.
  2. Enter the Image URL and descriptive Alt text. Adjust the width and height if needed, then click Apply.
  3. Click Preview email to check your message and personalization before saving.
  4. Click Save to save your email content and return to the content overview. Saving does not send the campaign or turn on the flow.

The size limit for all text-only emails is 1.05 MB. Send a preview to your inbox to check the email before sending it to recipients. If the preview fails, check the error message: template errors or preview-send limits can also prevent it from sending.
