If you’re sending emails but not seeing the revenue lift you expected, chances are your design is holding you back. Great email design is not about making things look “pretty,” it’s about building a structure that gets subscribers to open, engage, and convert.
At ASPEKT, we design and manage emails for six, seven, and eight-figure brands every day. In this guide, I’ll walk you step by step through the essential building blocks of an email template that actually drives sales. Whether you’re designing in Figma or directly inside Klaviyo, these principles will help you build emails that feel polished, persuasive, and profitable.
Before diving into design, let’s clarify one thing. Email is not a landing page. You don’t need 20 sections, animations, or overly fancy graphics. In fact, complexity often hurts performance.
The best-performing emails we send for clients follow a simple structure:
Header with branding
Hero section with headline, image, and call-to-action (CTA)
Featured products with descriptions and buttons
Social proof through reviews or testimonials
Footer with navigation and social links
When you structure your emails this way, every section builds momentum toward a click and a purchase. Let’s go through each part in detail.
Your header is the brand’s first impression. Keep it simple and functional.
Width: Standard email width is 600px
Height: Between 150–200px
Content: Logo aligned to the center or left, depending on your brand style
Colors: Stick with brand colors or neutral tones for maximum readability
Don’t overload the header with menus or multiple links. A clear logo and maybe one CTA (like “Shop Now”) is plenty.
The hero section is the centerpiece of your email. This is where you grab attention and guide readers to your main offer.
Use one strong image (product, lifestyle, or promotional banner).
Overlay a short headline that communicates the main message (think “New Drop Just Landed” or “Your Summer Essentials”).
Add a CTA button directly below the headline. Make sure it’s easy to tap on mobile.
Pro tip: Test adding a drop shadow behind your headline text or button to make it pop. Small design details can dramatically improve click-through rates.
After the hero, include a section that features a few products or categories. The goal here is to make browsing frictionless.
Create consistent image blocks with product photos.
Add short descriptions (1–2 sentences max).
Place CTA buttons (“Shop Now,” “Grab Yours,” “Buy Today”) under each product.
Keep spacing and sizing uniform so the section feels balanced.
This format mirrors a mini product catalog, which makes it easy for subscribers to explore without leaving the email.
People buy from brands they trust. That’s why testimonials belong in your email design.
Use customer names or initials for authenticity.
Add star ratings or badges for visual credibility.
Keep copy concise. One or two sentences is enough.
You can highlight reviews, showcase user-generated content, or even spotlight press mentions. Social proof reminds subscribers that others already trust your brand, which reduces hesitation.
Your footer is the place to wrap things up with utility and trust signals.
Include social media icons for cross-channel engagement.
Add standard disclaimers like unsubscribe links.
Keep the font smaller and simple to avoid distraction.
Think of your footer as the closing credits. It doesn’t sell, but it signals professionalism and compliance.
Once you’ve nailed the basic structure, here are some enhancements to test:
Auto-layouts in Figma or Klaviyo to keep spacing consistent across devices
Background color breaks to visually separate sections
Urgency elements like countdown timers during sales periods
Dynamic blocks in Klaviyo that swap in different content for different segments
These small optimizations compound over time, especially when you run A/B tests to see what resonates with your audience.
When reviewing hundreds of brand accounts, we’ve noticed the same design mistakes repeat over and over:
Over-designed templates that look great but perform poorly
No hierarchy (too many CTAs fighting for attention)
Unreadable fonts that clash with brand style
Too much copy that overwhelms the reader
Your goal is clarity, not complexity. Keep every section intentional and conversion-driven.
A single well-designed template can make or break your email performance. For one client, simply adjusting header placement, CTA positioning, and testimonial formatting lifted campaign revenue from $500 per send to $1,200 per send. That’s more than double the return with no extra traffic or ad spend.
Building emails that convert isn’t about reinventing the wheel. It’s about using a proven structure and layering on brand-specific touches. If you follow this framework — header, hero, product features, testimonials, footer — you’ll have a high-converting template ready to drive more revenue.
