Detected by 48 distinct extension users.
Distribution of brands using Loops by industry. Helps you gauge whether this ESP is popular with businesses similar to yours. Brands tagged in two industries are counted in both.

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 130 · promotions 18 (150 emails observed)
Percentages are averaged per brand (each counted once) across 11 brands using Loops with at least 5 placement observations each.
Underlying transactional infrastructure Loops routes through, detected from the sender hostname (PTR record) on each email's Received header. Bigger sample → more accurate.
