Every email tool, in one place.
The checks, previews and fixes you run before every send — gathered into a single toolbox, for a fraction of Litmus. Nothing leaves your browser unless you save it.
Live preview across Gmail, Outlook & Apple Mail.
One place, not four
Stop paying for Litmus, a deliverability tool, a verifier and five open tabs. One toolbox, one login.
Private by design
Campaigns and lists are checked in your browser. Nothing is uploaded unless you choose to — EU-hosted, GDPR-native.
A fraction of the price
The quality of the tools you already pay for, without the enterprise-only price tag. We undercut the incumbents on purpose.
One tool live today. The rest, landing soon.
