Email marketing for agencies and brands.
Campaign Monitor is the 23rd most popular marketing ESP we track.
Detected by 91 distinct extension users.
Distribution of brands using Campaign Monitor 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 40 of 67 brands tagged (60% 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 359 · promotions 10 · spam 4 (373 emails observed)
Percentages are averaged per brand (each counted once) across 17 brands using Campaign Monitor with at least 5 placement observations each.
64 as their primary ESP, the rest send transactional or secondary email through it. Primary users are listed first, then secondary.
