Salesforce Marketing Cloud gives email teams everything they need to send campaigns at scale. Journeys, automation, personalisation, and delivery are all enterprise-grade. Yet when it comes to making decisions about what to change, improve, or repeat, many Salesforce Marketing Cloud (SFMC) teams unknowingly rely on assumptions rather than evidence.
Not because they are careless.
Not because they lack experience.
But because behavioural insight is missing from standard SFMC reporting.
The Invisible Gap Between Data and Decisions
Most email campaign decisions start after a send:
“Should we keep this layout?”
“Do we need to move the CTA?”
“Did that design change help?”
“Why did performance drop?”
SFMC provides opens, clicks, and CTR. These metrics describe outcomes—but they don’t explain user behaviour inside the email.
When behaviour isn’t visible, assumptions fill the gap.
Where Assumptions Begin in SFMC Campaigns
Assumptions usually sound reasonable:
“The primary CTA must have worked”
“Users probably clicked the hero button”
“The layout feels clearer now”
“This section must be getting attention”
These statements feel data-driven because they follow metrics. But in reality, they’re interpretations without proof.
Salesforce Marketing Cloud reports confirm that something happened—not what actually happened.
Assumption 1: Clicks Mean the Right CTA Worked
One of the most common assumptions in SFMC is:
“If clicks happened, the main CTA worked.”
In reality:
Secondary links may be getting more clicks
Images may outperform buttons
Logos or footer links may inflate engagement
Because SFMC aggregates all clicks, teams can’t see which CTA actually mattered. Decisions are made on totals instead of intent.
Assumption 2: Design Changes Improved Engagement
After a redesign, CTR goes up slightly. The conclusion is often:
“The new design worked.”
But without behavioural insight, teams can’t confirm:
Which element benefited
Whether attention shifted positively
If improvements were accidental or repeatable
Design success becomes assumed rather than proven.
Assumption 3: Users Scroll and See Everything
Another quiet assumption is that users engage with the full email.
In practice:
Many users click early and exit
Lower sections may never be seen
Some content blocks may be completely ignored
SFMC reporting doesn’t show attention flow or drop-off, so teams assume visibility that may not exist.
Assumption 4: A/B Test Winners Explain Themselves
Salesforce Marketing Cloud supports A/B testing, but results often stop at:
Version B won
CTR was higher
Teams then assume:
The CTA was better
The layout was clearer
The copy resonated more
Without knowing how behaviour changed, these assumptions can’t be validated—and learning doesn’t scale.
Why Assumptions Persist in Mature Teams
Even experienced SFMC teams fall into assumption-based decisions because:
Reporting lacks behavioural depth
Stakeholders demand quick answers
Best practices feel “good enough”
There’s no visual evidence to challenge beliefs
Over time, assumptions harden into habits.
The Cost of Assumption-Led Email Optimisation
Assumption-based decisions lead to:
Repeated redesigns without clear gains
CTA changes that don’t move the needle
Testing fatigue
Slower performance improvement
Difficulty explaining results internally
Teams work harder—but not smarter.
Why Salesforce Marketing Cloud Reports Encourage Assumptions
SFMC reporting is excellent at summarising performance. But summaries encourage interpretation.
SFMC does not show:
Which links users preferred
Where clicks clustered
Which sections were ignored
How attention shifted across versions
Without this visibility, every decision requires interpretation—and interpretation invites assumption.
How CRMx Replaces Assumptions With Evidence
This is where CRMx Email Heatmaps fundamentally change how decisions are made in Salesforce Marketing Cloud.
CRMx doesn’t replace SFMC metrics. It explains them.
Behavioural Accuracy by Design
CRMx tracks clicks only on linked elements:
Linked buttons
Linked images
Linked text
Clicks on non-linked areas are not recorded.
This ensures:
Only intentional actions are analysed
No misleading engagement signals
Clean, decision-safe data
Seeing What Users Actually Choose
With CRMx, teams can clearly see:
Which CTA received the most clicks
Which links competed for attention
Which elements were ignored
Decisions are no longer based on what teams think users did—but on what users actually did.
Ending Guesswork in A/B Testing
CRMx allows teams to understand:
Which elements gained or lost attention between versions
Whether engagement redistributed meaningfully
Why one version outperformed another
This turns A/B testing into a learning engine, not a guessing exercise.
Aligning Teams Around Evidence
When behaviour becomes visible:
Designers understand what works
Marketers optimise with confidence
Stakeholders stop challenging assumptions
Decisions become faster and more consistent
Evidence replaces opinion.
Building a Repeatable Optimisation Process
With behavioural insight, teams can:
Identify winning patterns
Eliminate underperforming elements
Scale what works across campaigns
Create repeatable best practices grounded in data
Assumptions are replaced by proof.
Final Thoughts: Assumptions Are a Symptom, Not a Failure
Email campaign decisions in Salesforce Marketing Cloud are often assumption-based—not because teams lack skill, but because behaviour isn’t visible.
Salesforce Marketing Cloud shows outcomes.
CRMx shows behaviour.
When teams can see what users actually do inside emails, assumptions disappear—and confident, evidence-led decisions take their place.

If you want to understand which CTAs work, where attention goes, and why performance changes, it’s time to move beyond assumption-based optimisation.
