At a glance
What we observed in this category
Mailreach leads the email warmup tools category with a composite score of 45.0, nearly 14 points ahead of second-ranked Saleshandy at 31.2. That gap is meaningful because it reflects both visibility and citation strength: Mailreach holds 37.5% visibility and 62.5% citation rate simultaneously, a combination no other brand in the top 10 achieves. The category average visibility sits at just 8.1%, making Mailreach's 37.5% figure more than four times the norm.
The visibility-to-citation divergence is sharp across several brands. Smartlead and Lemwarm both match Mailreach's 37.5% visibility score, but Smartlead's citation rate is only 12.5% and Lemwarm's is 0.0%, meaning Google AI Mode names them without anchoring source documents to them. Conversely, Saleshandy (12.5% visibility, 75.0% citation) and Mailivery (0.0% visibility, 25.0% citation) are cited heavily relative to how often they are named, suggesting the AI trusts their content as a reference even when not spotlighting the brand directly.
The cited sources list shows Google AI Mode is anchoring heavily on third-party and community content rather than brand-owned pages. Warmforge.ai, YouTube, Skrapp.io, Reddit, Mailwarm.com, and Trulyinbox.com all appear as top cited sources alongside brand domains like mailreach.co and saleshandy.com. Every brand in the top 10 draws its top engine score from Google AI Mode exclusively, confirming this is a single-engine dominated category with no meaningful presence recorded from alternative AI platforms.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →
