When potential buyers ask AI engines like ChatGPT and Google AI about email marketing platforms, Klaviyo emerges as the standout leader. Notably, Klaviyo boasts a 37.5% visibility rate, far ahead of other top brands like Brevo and MailerLite. This high visibility suggests Klaviyo is frequently recommended and discussed among AI-generated responses.
The rankings are primarily shaped by sources like YouTube and aggregator sites such as Email Tool Tester and Zapier. These platforms provide extensive reviews and comparisons that AI references, making them influential in how brands are ranked. As these are review sites, they synthesize information from a range of user experiences and expert analyses.
For buyers evaluating their options, this ranking highlights the value AI engines place on recent reviews and third-party validation. Considering how much importance AI assigns to topical authority and extensive reviews in subcategories, buyers should prioritize platforms that are consistently praised by independent reviewers and have strong ongoing performance in these areas.
At a glance
What we observed in this category
Klaviyo leads the email marketing platforms category with a composite score of 33.8, jumping from rank 9 to rank 1 after its visibility rose from 0.0% to 37.5% in a single period. Brevo and MailerLite share that same 37.5% visibility mark yet score lower due to weaker citation rates. The gap between Klaviyo and the category average visibility of 11.2% is substantial, meaning most brands in the 20-brand set are largely absent from AI-generated responses.
Visibility and citation diverge sharply for several brands. MailerLite sits at rank 3 with 37.5% visibility but a 0.0% citation rate, meaning AI mentions it without linking to its domain. Constant Contact shows the inverse pattern, scoring only 12.5% visibility while holding a 25.0% citation rate, identical to Klaviyo's citation figure. GetResponse appears in citations at 12.5% despite zero visibility, suggesting AI sources reference it without surfacing the brand by name in responses.
Every brand in the top 10 registers Google AI Mode as its top engine, indicating this audit is entirely Google AI Mode-driven with no observable differentiation across other engines. The top cited external sources include youtube.com, emailtooltester.com, zapier.com, and reddit.com, pointing to review and tutorial content as the primary material AI anchors on when constructing email marketing responses. Brand-owned domains do not appear in the cited sources list.

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 →
