Hey it’s Edoardo from ElediaMails,
Most brands spend hours crafting their campaigns… choosing the perfect images, writing the best copy, and making sure the offer is irresistible.
But then fail to adapt to small, avoidable design mistakes that end up silently killing performance.
I see these all the time in audits, and they’re usually the reason why otherwise great emails underperform.
Let’s fix that.
📱 Mistake #1 – Not Mobile-Friendly
Over 70% of e-commerce emails are opened on mobile.
If your design isn’t responsive, you’re literally making it harder for the majority of your audience to read and click.
Bad mobile experiences = fewer clicks, more unsubscribes.
To fix this simply always make sure to also edit your email in the mobile view on Klaviyo to check if it looks like it’s suppsed to
🖼️ Mistake #2 – No Alt Text
If your images don’t load, your email could be a blank page.
And that happens way more often than most people think.
Adding alt text ensures your message still comes through, even if images are blocked and it’s also a great accessibility practice.
Quick fix:
Add short, descriptive alt text to every image
Keep it under 125 characters so it’s clear and quick to read
🌙 Mistake #3 – Not Optimized for Dark Mode
Dark mode is everywhere: From iPhones to Gmail to Outlook.
If your design doesn’t account for it, your email might look broken or unreadable for a large portion of your audience.
Quick fix:
Test designs in dark mode before sending
Avoid transparent PNGs with black text (they’ll disappear)
Use brand colors that contrast well in both light and dark themes
🎯 Final Word
Small fixes = big revenue impact.
These tweaks don’t take long, but they ensure your emails actually look as good as you intended - for every subscriber.
Great design isn’t just about pretty layouts… it’s about making sure nothing gets in the way of your audience engaging and converting.
