We found more conversion tactics here than on 46% of the 1,450 multi-step SaaS funnels we have measured.
4 pages walked · measured by Roentgen 1.27.0
Every figure on this page was read off the live site by Roentgen 1.27.0 on 2026-09-07, a script that reads page structure, computed CSS and matched text. No AI judgment, nothing estimated, and a capture’s numbers stay as read.
Detection coverage, not a verdict. A low count means we did not detect those patterns, not that the funnel is weak.
mailsenseai.com shows 5 of the 11 tactics that apply to a SaaS funnel, and we did not see the other 6.

Absence is a measurement, not a recommendation: we do not know why a tactic is missing, whether it belongs here, or whether adding it would change anything. Where a walk stopped early, a tactic living deeper would also read as not detected.

structural bands identified on this funnel, cropped from its own capture
the atomic pieces — price anchors, ratings, guarantees — with their verbatim on-page text
1 could not be measured, not counted either way
76% of measurable text passes WCAG AA. 4+ runs fail. 30% of text was unmeasurable (over images/gradients). not counted either way.
worst: “3rd open” at 3.66:1 (12px, #5b6bff on #edeeff). needs 4.5:1
Raise text/background contrast to ≥4.5:1 (≥3:1 for large text), especially on CTAs and body copy.
What this measuresSmallest sampled text is 11px, below the 13px floor this check uses.
Keep body copy ≥15-16px; reserve sub-13px for fine print only.
What this measures164 of 204 interactive targets are under 44×44px on mobile.
smallest: “Open menu” at 36×36px
Give tappable controls a ≥44×44px hit area. the touch minimum.
What this measures10 paragraphs run past ~95 characters per line.
Cap measure at ~60-75ch for comfortable reading.
What this measures1 heading skips a level (e.g. <h2> followed by <h4>). Screen-reader users navigate by this outline.
Step heading levels one at a time; use CSS for size, not a deeper level.
What this measuresNo same-page “skip to content” link was found. Keyboard users tab through the whole nav on every page.
Add a first-in-DOM <a href="#main"> that is visible on focus.
What this measures4 images are shipped at more than 2x the width shown.
“badge-light.svg” is 396px wide, displayed at 141px
Serve responsive sizes (srcset/sizes) matching the rendered width.
What this measuresMobile viewport · Language declared · Image alt text · Render-blocking resources
At least 1.4 MB across 123 measurable resources, but 93 cross-origin resources did not expose a size. The true weight cannot be determined from the page.

MailSenseAI vs Mailtrack
A match means this funnel's measurable surfaces fit the playbook's pattern — the quoted language is what fired the detection. A lever is one playbook mechanism observed on-page. We never claim what a brand's ads or emails do; a crawl can't see them. All funnel designs →
Two different things sit side by side here. The claim and its quoted evidence are measured on this funnel, the same way every other fact on this page is. The playbook itself is written guidance — our strategy library, not a measurement of this site — and it lives behind the links above. Nothing on this page recommends what this brand should do.
We measured 4 colour roles on this funnel.
