Cross-channel marketing for growth brands.
Iterable is the 7th most popular marketing ESP we track.
Detected by 274 distinct extension users.
Distribution of brands using Iterable 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 395 of 395 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.
By volume: inbox 5,121 · promotions 2,009 · spam 135 (7,265 emails observed)
Percentages are averaged per brand (each counted once) across 207 brands using Iterable with at least 5 placement observations each.
Underlying transactional infrastructure Iterable routes through, detected from the sender hostname (PTR record) on each email's Received header. Bigger sample → more accurate.
