eM Client Free vs Paid: What the License Costs

The eM Client free vs paid license cost question has a short answer and a long one. The short one: the free licence costs nothing, and the paid licences are sold either as a yearly subscription or as a one-time purchase, with the current numbers on eM Client's own pricing page.

The long one is what this post is for, because the free licence is not limited the way most comparison pages say it is. Those pages lead with the missing features. No snooze. No send later. No thread view.

Those matter less than three structural caps that decide the purchase for nearly everyone: two accounts, one device, and personal use only. This page draws that line first, then explains the part that costs people real money later, which is what a one-time licence actually buys.

The verdict: what you get free and what you have to pay for#

If you run one or two mailboxes on a single computer for personal reasons, the free licence is a complete email client and you should just use it. It is not crippleware. You get mail, calendar, contacts, tasks and encryption in the same interface paying customers use, and eM Client keeps the free licence on the newest major version rather than freezing you on an old one.

You have to pay in three situations, and really only three. You need a third email account. You want eM Client on more than one computer. Or you are using it for work at a company, school, non-profit or government body, which the free licence does not permit.

Everything else is a comfort argument, not a blocker. Snooze, send later, undo send, thread view, mass mail, quick actions, translation, Teams and Slack integration, signature and template libraries: all real, all worth money to some people, none of them the thing that forces the decision.

If none of the three apply, stop reading and install the free licence. If one does, the next question is not whether to pay but how, because eM Client sells the same licence two different ways and the five-year totals are not close.

There is a fourth situation this page comes back to at the end: you did not want a licence tier at all, you wanted the triage and the drafting done for you. Neither eM Client licence is built for that. We build AI Emaily, so read that section knowing whose site you are on.

eM Client free vs paid at a glance#

This is the whole comparison in one place, taken from eM Client's licensing and pricing pages as of August 2026. Deliberately no prices below, because they change and a stale number in a blog post is worse than no number.

The three caps that actually decide it#

Feature tables make the free licence look thin. In daily use it does not feel thin, which is why so many people run it for years. What ends the free run is almost always one of these three.

• Two email accounts. That is two accounts, not two addresses. A work mailbox, a personal Gmail and a side-project domain is three, and the third one will not connect. If your work mailbox is Exchange or Microsoft 365, it still counts as one account regardless of whether the client connects over Exchange Web Services or IMAP.
• One device. This is the cap people hit without expecting to. The free licence activates on a single machine. Add a laptop alongside the desktop and you are buying a Personal licence, which covers up to three devices for one user.
• Personal use only. The free licence excludes institutional use. A company, a school, a non-profit and a government department all need Business licences, and Business is priced per device rather than per person.

Where the free licence genuinely wins#

The free licence has one advantage the paid licences cannot claim: it costs nothing, forever, with no card on file and no renewal date. That is rarer than it sounds in email software, where most of the market has moved to trials that end.

It also gets major versions. eM Client says the free licence is always valid for the newest major version, which means a free user is on a newer build than a one-time paid customer who bought version 10 and never paid for the upgrade. That is genuinely counterintuitive, and it is the single most useful thing on this page.

The core client is the same core client. Multiple protocol support, calendar and contacts sync, message encryption, the same rendering and search. eM Client did not hollow out the free build to make the paid one look better.

And the mobile apps are outside the licence system entirely. eM Client's pricing page states the iOS and Android versions do not need a licence and are free to use, so a free desktop user is not locked out of their phone.

Where the paid licence earns its money#

Past the caps, the paid tiers are mostly about time. Snooze, send later, watch for reply and undo send are all small features that remove a recurring decision from your day, and they compound if you handle a lot of mail.

Thread view is the one worth calling out separately. Reading a long back-and-forth as a conversation instead of as loose messages changes how the inbox feels more than any other single item on the list, and it sits behind the paywall.

Template and signature libraries, quick actions and automatic translation matter to a specific kind of user: someone sending similar messages repeatedly, or working across languages. If that is not you, they are not worth the line item.

Business adds an administrative layer rather than features: a License Manager for assigning and remotely deactivating seats, plus centrally set signatures and templates. That is what you are buying at company scale, and it is the reason Business exists as a separate tier rather than a volume discount on Personal.

Subscription or one-time: what lifetime actually covers#

This is the decision that costs money, and it is the one most comparison pages skip. eM Client sells the same Personal and Business licences two ways, and they behave very differently after year one.

A subscription keeps you on the newest major version and keeps VIP Support live. A one-time purchase never expires, but it is tied to the major version you bought. When the next major version lands, that upgrade is a separate purchase unless you added Lifetime Upgrades, which is eM Client's rider for always getting the newest major version on a perpetual licence.

So the phrase people search for, eM Client lifetime licence cost, is really two purchases: the perpetual licence, and the Lifetime Upgrades rider that makes it behave like one. Buy only the first and you own that version forever, which is a real thing to own, just not the thing most buyers assume they bought.

Is eM Client free for commercial use?#

No. eM Client's licensing page limits the free licence to personal use and specifically excludes companies, schools, non-profit organisations, government bodies and other institutions. Those need Business licences.

The Personal licence sits in between, and the boundary catches people out. It covers individuals, freelancers and sole proprietors. So a solo consultant invoicing clients is inside Personal. The moment there is a company around you, you are in Business territory, and Business is counted per device rather than per person.

That per-device counting is the part worth modelling before you buy. Ten staff with a desktop and a laptop each is twenty device licences, not ten. eM Client publishes a discount for NGOs, schools and universities and points larger deployments at its sales team, so check both before you total it up yourself.

Who each licence is genuinely for#

Reduced to the actual decision, with no hedging.

• Free licence: one person, one computer, one or two mailboxes, nothing to do with work. Also the right answer if you want a desktop client with no recurring cost at all, which is a legitimate requirement and getting harder to satisfy.
• Personal, subscription: an individual or freelancer on two or three machines who wants the newest version and the support line, and does not want to think about upgrades again.
• Personal, one-time plus Lifetime Upgrades: the same person who would rather pay once. Add the upgrades rider or you are buying a version, not a product.
• Business: any company, school, non-profit or public body, priced per device. Budget for devices rather than headcount, and ask about the NGO and education discount if it applies.
• None of the above: you are not short a feature, you are short the time to work the inbox at all. That is the next section.

A third option, honestly: when the licence tier is not the problem#

Some people arrive at this comparison having already decided that neither answer is right. They are not blocked by a two-account cap. They are opening a client that works fine and still spending an hour a day sorting and replying.

That is the problem AI Emaily is built for, and we build it, so treat the rest of this section as the vendor describing its own product. AI Emaily is an AI-native client across Gmail, Outlook and IMAP with an agent that triages the inbox, drafts replies and closes follow-up loops. It runs in one of three modes: Manual, Copilot where nothing sends without your approval, and a gated Autopilot, with undo and a full audit log of every action the agent took.

The drafting voice comes from a Personal Context brain and per-client profiles that you set, not from a model reading your sent mail. We do not train on your mail and we run zero retention with model providers.

Now the honest half, because it is the half that matters on a page about licence cost. AI Emaily has no free tier. It is a 7-day free trial on Pro or Autopilot, card required, and nothing charged if you cancel before day seven. If a permanent zero-cost licence is your requirement, eM Client's free tier wins outright and we have nothing to offer you.

We also have no perpetual licence. AI Emaily is a hosted service with the agent running server-side, so there is no version you buy once and keep, and eM Client's one-time purchase is a shape we cannot match. On desktop we ship a real downloadable Mac app, Apple Silicon only, plus a Windows installer, both an Electron shell around the web app rather than a native binary. Android is a PWA, there is no Linux build, and our offline mode covers reading and drafting rather than the complete local archive eM Client keeps.

Where we are the better answer is narrow and specific: several mailboxes, high volume, and a willingness to pay monthly for the sorting and the first draft rather than for a feature list. Where eM Client is the better answer is everywhere the requirement is a good, cheap, locally stored client that you control end to end.
