Plan, approve and remember every email your team sends.
One workspace for your whole email programme — plan campaigns, keep every send on-brand, approve the work, and keep a searchable record of everything you've sent. It works around your ESP, not instead of it.
The workspace that sits around your email platform.
Your ESP sends the emails. Mailfois runs the operation around them — what you plan, how you keep it on-brand and approved, and what you learn from every send.
Plan
Campaign calendar, owners, approvals and deadlines.
Create
Your builder & ESP.
Govern
Brand rules, accessibility, consistency and sign-off.
Send
Your ESP.
Learn
Performance, deliverability, reputation and insights.
Mailfois owns Plan · Govern · Learn — the connective tissue no ESP provides. Your platform keeps Create & Send.
One layer above your entire email stack.
Send where you already send. Everything around the send — and the record of it — lives in Mailfois.
One place, not four
A testing suite, a deliverability tool, a verifier and five open tabs — replaced by one workspace, one login.
Private by design
Campaigns are checked in your browser, never uploaded. GDPR-native, UK-first.
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.
The workspace that runs your whole email operation.
Everything a team needs around email — dream it up, plan it, keep it on-brand, approve it, archive it and learn from it — in one place above your ESP. All live today, with no migration and no change to how you send.
