Technix Infotech audited and completely redesigned a MasterSoft event campaign email that scored 45/100 on quality metrics, transforming it into a professional, conversion-optimized template ready for deployment.
The Challenge
MasterSoft's event invitation email had rendering issues across email clients, broken personalization tokens, inconsistent branding, and no clear CTA hierarchy.
The email was scheduled to send to their entire database. Sending a broken email to thousands of contacts would damage brand credibility.
Quality score on the original email. Rendering issues, broken tokens, and unclear CTAs made it unfit for deployment.
Why This Was Not a Standard Project
Email HTML rendering varies dramatically across clients (Gmail, Outlook, Apple Mail). What looks fine in one breaks in another.
The redesign needed to maintain the original messaging while fixing every technical issue and improving conversion design.
Technix conducted a systematic audit across 15 email clients using Litmus testing, identified 23 rendering issues, fixed all of them, and redesigned the CTA hierarchy to follow a single clear conversion path.
What We Did
Audit
Day 1-2Tested across 15 email clients. Identified 23 rendering issues, 3 broken tokens, and 5 CRO problems.
Redesign
Day 3-5Rebuilt the template with responsive tables, fixed personalization, sourced brand assets, and redesigned CTA flow.
QA and Delivery
Day 6-7Retested across all clients. Validated personalization. Delivered production-ready template.

The Technical Deep Dive
The 23 rendering issues spanned Outlook desktop (which uses Word's HTML engine), Gmail (which strips most CSS), and Apple Mail (which handles media queries differently).
Each fix had to work across all 15 clients simultaneously. Fixing an Outlook issue often broke Gmail rendering, requiring creative CSS solutions.
The redesigned email rendered perfectly across all 15 tested email clients, passed every personalization test, and provided a clear single-path CTA hierarchy that guides readers toward registration.
The Results
| Metric | Before | After |
|---|---|---|
| Quality Score | 45/100 | Production-ready |
| Rendering Issues | 23 across clients | 0 |
| Broken Tokens | 3 personalization failures | 0 |
| CTA Clarity | Multiple confusing links | Single clear conversion path |
