Hi, I’m Alex, founder of The Frontend Company. In this post, I’d like to walk you through a common scenario we’ve seen with SaaS platforms: strong email performance that falls flat due to poor post-click UX. And more importantly — what you can do about it.
The Issue: When Email Performance Doesn’t Match Conversions
One of our recent clients — let’s call them Invoici — is a B2B SaaS platform specializing in invoicing automation. Their marketing team had launched an email campaign with impressive performance metrics:
- 38% open rate
- 11% click-through rate (CTR)
But there was a problem: the email-to-signup conversion rate was below 2%.
We often see this disconnect. Marketers assume low conversions mean weak messaging or unqualified traffic. In reality, it’s often a UX problem post-click.
And Invoici’s case was a textbook example.
UX Friction Points We Identified
When we audited the landing experience, we found:
- Page load speed was above 4.5 seconds (on mobile). Google research shows that bounce rates increase by 32% when load time goes from 1 to 3 seconds.
- CTA was not visible above the fold. Eye-tracking studies (Nielsen Norman Group) show that users spend 57% of their time above the fold — yet the signup form was halfway down the page.
- Inconsistent visual design. The email had a modern, clean tone — the landing page felt outdated and text-heavy.
- No clear value reinforcement. Users clicked with intent, but the landing page failed to continue the narrative that started in the email.
The Solution: A UX-First Redesign
We implemented a frontend overhaul that focused on continuity, clarity, and conversion:
1. Performance optimization
- Migrated from WordPress to Next.js
- Reduced load time from 4.5s to 1.6s
- Minimized third-party scripts
2. Visual and content alignment
- Matched typography, colors, and visual assets with the email campaign
- Created visual hierarchy around the main call-to-action
- Used product screenshots to support messaging
3. Conversion-focused structure
- One CTA above the fold
- Embedded trust signals (customer logos, testimonials)
- Form fields reduced to essential minimum
4. Mobile-first adjustments
- Made touch elements larger and more accessible
- Reorganized spacing for smaller screens
- Deferred non-critical content
The Result
Over the following 4 weeks, the impact was measurable:
Metric | Before | After |
|---|---|---|
Email-to-signup conversion | 1.9% | 5.6% |
Bounce rate | 62% | 29% |
Avg. time on page | 23 seconds | 1 minute 18 seconds |
Page load (mobile) | 4.5s | 1.6s |
A conversion lift of nearly 3x from the same traffic source — no additional ad spend or email tweaks needed.
Conclusion
- Email marketing doesn’t end at the click. The post-click UX is part of the funnel, and arguably the most decisive part.
- Landing pages should feel like a continuation of the email. Not just in messaging, but also in tone, visuals, and emotional intent.
- Friction kills intent. A user who clicks is ready to act — your interface either enables them or discourages them.
If your email marketing is delivering traffic but not results, it may not be your campaign that needs fixing — it may be your front-end.
At The Frontend Company, we help SaaS platforms optimize this entire journey, from first click to successful signup. If you're seeing similar patterns, I’d be happy to take a look.
