Campaign dashboards from our own agency and our clients, every monthly placement test we have run on prewarmed stock, and the routing data behind how we build. Read off the screens, not retyped.

Live campaign results
Campaigns run by our own agency and by clients, on the same infrastructure we sell. Sends, reply rate and pipeline, as the sequencer reports them.
Figures as each campaign’s sequencer dashboard reports them, for campaigns run by our agency and by clients. Reply rate is replies divided by emails sent; pipeline is the opportunity value recorded against those replies, not closed revenue.
These are campaign outcomes, which depend on the list and the offer as much as on the infrastructure. The placement tests below are the part that is ours alone.
8 monthly tests
Inbox placement tests
We build a new batch of prewarmed domains and inboxes every month and seed-test it before any of it reaches a customer. Every inbox is scored on its own, and only those clearing 95% go into the pool. 469,331 messages scored so far, 95.17% into the primary inbox.
Nothing is deployed below 95%. The most recent test, October 2026, scored 94.47% across 135,600 messages. The full log publishes every month, including the ones that went badly.

What routing is worth
The same offer and the same list source, sent from different platforms to different recipient platforms. They ran at different times rather than side by side — each dashboard carries its own dates — so read the gaps as consistent and large rather than as a controlled test.
Monitoring
What we watch after delivery
Placement, spam rate and domain health are tracked per domain once stock is in the pool, so a blacklist hit or a reply-rate drop surfaces as an event rather than as a mystery three weeks later.
Verified
Checked by someone other than us
Our team is certified by the sequencer most of this data comes out of, and every blocklist claim on this site is one you can run yourself against your own domains.
Independent checks are better than our screenshots. The blocklist, authentication and placement tools on this site run the same queries we run, against whatever domain you give them, free and without an account — the sweep behind our SURBL study is the bulk SURBL checker pointed at our own fleet.

Reading about deliverability gives you insight into the state of cold email. Running tests on your own infrastructure tells you the state of your cold email.
