Kit is the 5th most popular marketing ESP we track.
Detected by 207 distinct extension users.
Distribution of brands using Kit 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 334 of 396 brands tagged (84% coverage). 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.
By volume: inbox 4,106 · promotions 177 · spam 28 (4,311 emails observed)
Percentages are averaged per brand (each counted once) across 144 brands using Kit with at least 5 placement observations each.
Underlying transactional infrastructure Kit routes through, detected from the sender hostname (PTR record) on each email's Received header. Bigger sample → more accurate.
384 as their primary ESP, the rest send transactional or secondary email through it. Primary users are listed first, then secondary.
