Built by someone who's lived the email grind.
Mailfois is the workspace modern email teams run their whole programme in — around whatever platform they already send from. It didn't come out of a strategy deck. It came out of years of doing the job, and getting tired of everything that happens around the actual email.
The email was never the hard part.
In most teams, building the email is the quick bit. The slow, messy bit is everything around it — working out what's going out and when, chasing sign-off across email threads and Slack, keeping every send on-brand, and then hunting for "that campaign we sent last spring" long after the preview link has expired.
That work lives in spreadsheets, inboxes and people's heads. Nothing joins it up, and when someone leaves, a chunk of it walks out the door with them. Mailfois pulls it into one calm place — and, crucially, gives your team a memory of everything it's ever done.
Hi, I'm Liam.
I've worked in marketing for over 10 years, and in email marketing specifically for the last 7 — planning and building campaigns across platforms like Marketo, Bloomreach and Silverpop (back when it was still called Silverpop, before it became Acoustic). I genuinely love the craft of a good email.
What I didn't love was the admin around it: the approval ping-pong, the endless "is this on brand?", the history that vanished the moment a link expired, and the five separate tools open in five separate tabs. I kept wishing for one place to run the whole operation calmly. It didn't exist — so I built it.
Mailfois is the tool I always wanted. Opinionated where it helps, out of the way where it doesn't, and shaped around how email teams actually work rather than how a big platform wishes they did.
How a campaign flows through it.
It follows the real shape of the work — from a half-formed idea to a signed-off send you can find again years later. Your platform still does the sending; Mailfois runs everything around it.
1 · Ideas
Start the spark
Brainstorm together on idea boards, then promote the winners straight into the plan.
2 · Plan
Get it on the calendar
Schedule the send, assign a builder, and set build, sign-off and send dates that stay in order.
3 · Sign-off
Approve with a trail
Review, comment, tick the build checklist and approve — every decision recorded, on-brand and accountable.
4 · Remember
Keep it forever
Every signed-off email is saved as a live preview and made searchable — your team's institutional memory.
All of it sits above your ESP — no migration, no change to how you send.
Made for UK and US teams, private by design.
Mailfois is built with both UK and US teams in mind, and it takes your data seriously. The free tools run entirely in your browser — your campaigns are checked on your own machine and never uploaded. It's GDPR- and PECR-native for UK senders, with full US (CAN-SPAM) support built in.
It leans UK-first today simply because that's what I know best — and I'm deliberately learning more about how US teams work as the product matures, so it keeps getting sharper on both sides of the Atlantic.
Your campaigns, your history and your brand rules stay yours. No ads, no reselling data, no lock-in — you can export and walk away whenever you like.
