Average placement for brands using SparkPost

Where this ESP's emails land in Gmail. Each brand counted once (average of per-brand percentages) so a single high-volume sender can't dominate. Spam placement is mostly driven by the sender (list quality, content, complaint rate). This number reflects both the ESP's infrastructure AND the kind of senders who choose it — not just deliverability quality.

By volume: inbox 4,049 · promotions 478 · spam 83 (4,610 emails observed)
