# Case Study: How Redesigning Our Email Templates Increased Open Rates by 30%

***

### The Problem: Great Content, Low Opens 😩

Our emails looked good, our offers were solid, and our lists were warm…\
But the numbers told a different story: **low open rates**, sluggish engagement, and slipping conversions.

Sound familiar?

We knew we had to rethink not just what we were sending — but **how we were designing** it.

The result? A strategic overhaul of our email templates that led to a **30% increase in open rates**, stronger click-throughs, and a measurable lift in revenue.

Here’s exactly what we did — and how you can apply it to your own email campaigns.

***

### 📉 Before the Redesign: What Wasn’t Working?

***

#### ❌ Overly Graphic Headers

* Looked nice but screamed “promotion”
* Triggered image blocking in Gmail and Outlook
* Took too long to load on mobile

***

#### ❌ Weak Preview Text

* Defaulted to random alt text or fallback copy
* Didn’t support or complement the subject line

***

#### ❌ Cluttered Layouts

* Multiple CTAs in one email
* No visual flow
* Low click intent due to too many options

***

#### ❌ Inconsistent Branding

* Varying button styles
* Different tones across campaigns
* Fonts and colors were off-brand

***

### 🎯 The Redesign Strategy: What We Changed

***

#### 🧠 1. Focused on Subject Line & Preview Optimization

We used A/B testing and **SenderWiz’s rotation feature** to test:

* Personalized subject lines
* Urgency vs. curiosity phrasing
* Emojis (when appropriate)
* Preview text variations

**Result:**\
✅ 18% increase in opens just from better subject/preview combinations.

***

#### 🎨 2. Simplified the Template Design

We moved to:

* Single-column layouts
* Clear visual hierarchy (headline → image → CTA)
* Responsive design that stacked cleanly on mobile

💡 Load time improved dramatically, reducing bounce rates.

***

#### 🔁 3. Introduced Content Rotation

Using **SenderWiz’s smart rotation**, we started rotating:

* Subject lines
* Hero images
* CTA copy
* “Recommended for you” product sections

**Result:**\
✅ Reduced email fatigue\
✅ Made every version feel more personal — at scale

***

#### 🎯 4. CTA Overhaul

We:

* Made CTA buttons consistent in shape and color
* Moved primary CTA above the fold
* Added a secondary CTA below the fold (but made it less prominent)

**Result:**\
✅ Click-through rate increased by 22%.

***

#### 🎯 5. Brand Alignment

We created a mini brand guide for email:

* Fonts
* Button styles
* Color palette
* Logo usage rules

**Result:**\
✅ Emails felt instantly recognizable — and more trustworthy.

***

#### 📱 6. Mobile-First Formatting

We used SenderWiz’s mobile preview mode to:

* Optimize text size
* Make sure buttons were easily tappable
* Ensure spacing felt natural for small screens

**Result:**\
✅ 70% of our opens now came from mobile — and mobile conversions doubled.
