The whole workspace — priced for teams, not enterprises.
The free tools are free forever. When you're ready for the workspace — ideas, planning, sign-off and approvals, brand governance, library, search and deliverability — it's a fraction of what the incumbents charge, and it does far more than test emails.
Litmus tests your emails. Mailfois runs the operation around them — planning, governance, approvals, deliverability and reporting. Litmus no longer publishes prices, and its entry Core plan is listed at $500/month for five users. The same five get Mailfois Team's entire workflow for a fraction of that. Litmus renders your emails in 100+ clients and Mailfois doesn't, so here's an honest comparison.

The system that sits above your email platform.
Mailfois doesn't replace your ESP. Your ESP sends the emails; Mailfois manages everything around them — plan, govern, approve and learn. That distinction is the whole product.
Plan
Calendar, owners, approvals, deadlines.
Create
Your builder & ESP.
Govern
Brand rules, accessibility, sign-off.
Send
Your ESP.
Learn
Performance, deliverability, reputation.
Good to know.
Who is Mailfois for?
Email marketers, CRM and lifecycle teams who send through an ESP like Klaviyo, Braze, Bloomreach or HubSpot and want better planning, governance, approvals and reporting around their sends — without signing another enterprise contract.
Do you replace my ESP (Klaviyo, Braze, Bloomreach…)?
No — Mailfois sits above your ESP. You keep sending where you send; Mailfois runs the planning, governance and learning around it, so every campaign is on-brand, approved and improving.
What's actually live today?
A lot. Alongside the full free tool suite and pre-send checker, the whole team workspace is live: Idea boards, the Campaign Planner, Sign-off & approvals, Brand Center & Brand Guard, the Email Library, Showcase (emails and results as a shareable video or MP4), Documents, workspace-wide Search, Insights, and the in-app Tools (Handy links, Build checklist, Deliverability Auditor, Sender Reputation Monitor), plus Copy Bank for translation, two-stage client sign-off and Agency mode. New features roll out to your plan as they ship.
Why is it so much cheaper than Litmus or Email on Acid?
Those are testing tools that recently got more expensive and more disruptive. Mailfois is a new category — planning, governance and reputation as one workspace — built lean and priced to grow a community, not to squeeze enterprises. You get more, for less.
Is there a free trial?
Yes. Pro, Team and Agency all start with 14 days free on a workspace's first subscription, so you can try everything with your own campaigns. Cancel any time in the 14 days and you won't be charged. The Free plan stays free for as long as you like.
How does per-seat Team pricing work?
You pay per active member of your workspace, from three seats up. Invite a teammate and they're on the same plan. It's the honest model for tools a team uses together.
How does the Agency plan work?
Your agency workspace pays for your own team, at least three seats. Each client gets its own workspace with its own plan, brand kit and library, and every client workspace gets the paid features through your plan. Ten client workspaces are included. Each one after that adds a small monthly fee, and your bill updates on its own when you add or remove a client. People on the client side who only approve or comment never need a seat. There's a 14-day free trial, and nothing is charged until it ends.
Is my data private?
Yes. The tools analyze your campaigns in your browser — nothing uploaded. The server-side tools (Auditor, Monitor) only ever touch public DNS and your own reports, never your lists or content.
A bigger team, or a few questions?
Questions, or need Enterprise (SSO, multiple brands, ESP integrations)? Leave your email and we'll be in touch. No spam.

The free tools are here to stay — free, private and ad-free. If they've saved you time and you'd like to chip in, you're very welcome to. There's no set amount: give whatever feels right.
Support Mailfois →No pressure and no set price — $10 is just a suggestion. On the checkout page, use the quantity stepper to set any amount you like: each unit is $1, so 10 = $10, 25 = $25, and so on.
