Should your email newsletter be one big image?
A polished artwork file is only the starting point. Build an email whose message still makes sense when its images do not load.

For most brand newsletters, use an HTML email with live text, separate images and descriptive text links rather than one long image. Keep the headline, essential information and next step readable without downloading the artwork. Slicing a PNG into smaller pieces does not make its words live text.
Start with the images-off reading experience
A designer can export an entire newsletter as a beautiful image. The recipient, however, sees whatever their email application chooses to load. If the offer, event date and action all live inside that artwork, the message depends on one display condition.
Campaign Monitor explains that client settings and firewalls can block remote images. It recommends combining text with images and providing a web-version link. Senders cannot override the recipient’s image-display setting.
Our first review is straightforward: disable images and read the message again. Can someone identify the subject, understand the useful information and follow the intended next step? If not, rebuild the content structure before fine-tuning the artwork. This checks comprehension; it does not establish deliverability or promise a commercial result.
Give text and imagery different jobs
Live text means words entered in the email editor’s text blocks or included as text in its HTML. It is different from lettering flattened into a photograph or promotional graphic. Mailchimp’s accessibility guidance recommends keeping critical information in text and using images to complement it.
For a hypothetical event invitation, make the event name, date, location, short explanation and registration link live text. Use the visual to establish the mood or show what attendees can expect. Readers should be able to understand the invitation before the image appears.
- Text carries the decision: the headline, summary, date, relevant conditions and next step.
- Images add evidence or character: a product detail, photograph or illustration.
- Links describe the destination: “View the event programme” tells the reader more than “Click here”.
W3C’s images-of-text tutorial explains the flexibility of real text for resizing and reading preferences. It is web guidance, not an assurance that a browser’s CSS effects will work in an email client. Use the principle while checking the email implementation separately.
Keep the brand through repeatable modules
Live text can still belong to a distinctive design. Colour, spacing, heading scale, image selection and the rhythm between sections give a newsletter its character. Our note on brand consistency looks at how these decisions hold together across different media.
For a short newsletter, we suggest an opening message, a set of useful story or offer modules, and a clear closing action. Each module should remain understandable when its image changes. Adding a story should not require the editor to export the entire newsletter again.
Review the design on an actual phone. If the text is too small, revise the content or layout rather than only increasing the image resolution. Give each relevant story its own destination instead of relying on one large linked picture to handle every reader intention.
That modular structure is an LMC production recommendation, not a universal template or an experimentally proven optimum. Choose the number of sections according to the information the reader needs.
Use alt text for the image, not the whole newsletter
Mailchimp’s alt-text guide recommends short, contextual alternatives that explain the image’s contribution. It also notes that some email clients may not display alt text for linked images. A long alternative attached to one giant graphic is therefore a poor substitute for a structured message.
Move the essential information into the body first. Then consider what additional meaning each image contributes and write an appropriate alternative. A filename or the word “image” is not a useful description. Check the saved alt text and its behaviour in the actual test email.
The aim is not to make someone hear the same paragraph twice. Read the message and its image alternatives together, and check whether the sequence adds information or merely repeats it.
Specify a working email in the agency brief
Decide what is being bought: a visual concept, a template assembled in your sending platform, or HTML to be imported into it. Those are different delivery scopes. A design screenshot cannot confirm that the final email is ready to send.
When preparing the creative brief, name the sending tool, the person who will update the copy and the person who will approve the campaign. We suggest requesting:
- The editable design source and separate visual assets.
- The agreed platform template or HTML deliverable.
- Subject line, preview text, body copy and destination list.
- Image alternatives, checked URLs and an identifiable test version.
- A named approver and a record of the final checks.
This is a suggested handover, not a format required by every provider. When discussing content and design services, agree on assembly and testing as well as appearance.
Approve the test email, not just the artwork
Open test messages in the desktop and mobile applications relevant to your audience. Check images on and off, reading order, link destinations and comfortable text size. Include dark mode where relevant. One preview is not proof of identical rendering everywhere.
Mailchimp generates a plain-text version of HTML campaigns and allows it to be edited. Review that output too: the message and destination addresses should still make sense.
Follow the body links and the web-version link. Compare the sent test with the approved copy and design, then record which version was checked. Tell us about your newsletter with the platform, audience and an example issue, so we can scope the design, build and review work together.
Frequently asked questions
Does slicing the artwork into several images solve the problem?
Not by itself. Words inside those slices remain image-based. Rebuild the essential message, dates and call to action in the email’s live text fields.
What is the right text-to-image ratio?
We do not prescribe a single percentage. First make sure the message and next step remain understandable with images disabled, then choose visuals for the information or character they add.
