Squarespace is the 47th most popular marketing ESP we track.
Detected by 28 distinct extension users.
Distribution of brands using Squarespace 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 13 of 21 brands tagged (62% 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 50 · spam 7 (65 emails observed)
Percentages are averaged per brand (each counted once) across 2 brands using Squarespace with at least 5 placement observations each.
Underlying transactional infrastructure Squarespace routes through, detected from the sender hostname (PTR record) on each email's Received header. Bigger sample → more accurate.
19 as their primary ESP, the rest send transactional or secondary email through it. Primary users are listed first, then secondary.
