Detected by 4 distinct extension users.
Distribution of brands using OneSignal by industry. Helps you gauge whether this ESP is popular with businesses similar to yours. Brands tagged in two industries are counted in both.
Based on 3 of 3 brands tagged. Industries assigned automatically using AI; not every brand is tagged yet.
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.
Not enough placement data yet for OneSignal (need at least one brand with 5+ observations).
Underlying transactional infrastructure OneSignal routes through, detected from the sender hostname (PTR record) on each email's Received header. Bigger sample → more accurate.
2 as their primary ESP, the rest send transactional or secondary email through it. Primary users are listed first, then secondary.
