Built on the Instantly API

Advanced analytics for
Instantly power users.

Deliverability health, statistically-sound A/B tests, pipeline attribution, and the trends Instantly’s own dashboard can’t show — for teams running cold email at scale.

TOFU/ˈtoʊ.fuː/noun

Top Of the FUnnel — the sends, domains, and replies before anyone’s a customer. Also: a soy block with surprisingly sharp analytics.

The reply rate Instantly buries. The spam placement warmup hides. The pipeline no one attributes. TOFU surfaces all of it.

What you get

Every metric that actually moves outbound.

Six analytics surfaces, built on the data Instantly exposes but doesn’t make usable.

Domain & mailbox health

Roll thousands of mailboxes up to sending domains with explainable 0–100 health scores, bounce alerts, and drill-down.

Placement vs. warmup

Catch the “false green” — where Instantly’s warmup score says healthy but seed tests say spam.

Real A/B significance

Two-proportion tests with p-values and sample-size gates. No more false winners from raw reply counts.

Campaign performance

Funnel, pipeline attribution, and a campaign leaderboard — which campaigns actually create opportunities.

Interest trends

Watch interested → booked → closed move over time. Instantly only shows today’s totals; we keep the history.

Agency rollup

Every client workspace in one view — deliverability, pipeline, and at-risk domains across the book.

The false green

Warmup says healthy. Seed tests say spam.

Instantly’s warmup score can read 90% while your real inbox placement is 40%. TOFU reconciles warmup against seed-test placement and tells you where you actually land — before a campaign tanks.
