Where all 99,351 tracked emails landed in Gmail
Average placement across brands that use each ESP. A brand can count toward multiple ESPs (e.g. Mailchimp for marketing + SendGrid for transactional both get credit for the brand's placement profile). Each brand needs at least 5 placement observations and ≥2 observations of the ESP being credited, so noise attributions don't skew the numbers. ESPs need at least 3 qualifying brands AND 200+ total tracked emails to appear.
Important context: spam placement is mostly driven by the sender (list quality, content, complaint rate, authentication setup), not the ESP. These numbers reflect both the ESP's infrastructure AND the kind of senders who choose it. A high spam % can mean weak IP reputation, lax abuse enforcement, or simply a customer base sending more aggressive content.
