Images in email: do you really need them? (B2C, B2B & everything else)
Short answer: sometimes.
Long answer: only when they help the message, not carry it.
If the email doesn’t make sense without the pictures, the design is carrying too much weight.
B2C / D2C (the “pretty but heavy” problem)
We’ve been designing emails like web pages for over a decade: big hero images, tiny text on images, sloooow loads, unreadable on mobile.
When images don’t load, the whole thing falls apart:
Use “layering”
Place images as background/visuals and put live text on top (from your builder), not text baked into the image
Write alt text like real copy
If images are off, the story still flows
Design in your ESP
Not Canva to image. It rarely renders as you expect.
Trust your users
If the copy creates curiosity, they’ll download images. Example: I opened a Hair Syrup email, live copy hooked me, then I downloaded images to see the before/after. That's images supporting the message.
B2B (hello Outlook 👋)
Expect images to be blocked by default, especially in the preview/reading pane.
That means:
Don’t hide essentials
In an image (dates, times, agenda, pricing, CTA). Use buttons + live text.
Images-off ≠ failure
Outlook blocking images also blocks the tracking pixel, so “opens” under-report.
Try (nearly) image-free
Logo + one purposeful visual only. Use images when they upgrade clarity: e.g., a static mock of the guide you’re offering or a quick flipbook/GIF to show depth.
Quick checks
Turn images off in testing. Does it still read? If not, fix the copy/structure
Alt text = micro copy. No “image123.jpg.” Tell me what I’m missing in a sentence
One job per image. If a visual doesn’t clarify or compel, it’s decoration. Bin it.
Keep it light. Compress files; avoid giant PNGs; favour SVG for simple icons where supported.
Never make the CTA an image
you's challenge this week
Give one B2B email with logo + one visual max; rewrite the lead with live text.
Ship one B2C email using layering only (no text-on-image); beef up alt text to read like body copy.
In Litmus/Email on Acid (or your builder preview), toggle images off and fix anything that breaks.
