What this means for the market
This daily Email Marketing snapshot is useful because it shows which brands language models make easy to recommend. Klaviyo leads with 91 GPI, but the practical question is where assistants explain alternatives, cite sources, or shift users toward a specific provider.
HubSpot has the clearest positive movement (+5 vs 22 May 2026), while Klaviyo is the main negative signal (−1). For marketing and search teams, that means checking the prompts, product claims, and official pages that models can quote when answering comparison or buying-intent questions.
The main automatic signal in this issue is "Sendinblue splits by persona cohorts with a 72-point gap", which helps separate a simple table move from a change in how models frame recommendations. GPI is not market share or revenue forecast; it is an observability layer for AI recommendations. Small moves are directional, while repeated movement across issues should trigger content, citation, and positioning review.

FAQ for Email Marketing
How should executives read this Email Marketing daily report?
Treat GPI movement above 5 points with medium or high confidence as strategic signal. Smaller shifts are directional and should be monitored over consecutive daily issues against baseline 22 May 2026.
Does this report measure market share?
No. GPI reflects AI recommendation visibility and framing quality across model answers, not revenue or shipment share.
How often is this report refreshed?
Daily pipeline runs rebuild this issue from the latest completed measurements, then publish a dated snapshot for comparison.
How should we use new entrants in decisions?
Treat first-time entrants as provisional until they appear in consecutive issues with medium or high evidence.
Which signals matter most in the Email Marketing leaderboard?
For Email Marketing, read rank together with GPI movement, evidence points, and model-level visibility. A brand that is strong in one model but absent in another needs a different response than a brand with broad but flat visibility.
