Why People Are Looking for eM Client Alternatives
The Pricing Shift in eM Client v9
eM Client's "lifetime" license has always had a catch worth knowing about: the perpetual option (around $59.95) covers your current major version only. When eM Client ships the next major release — v9 to v10, for example — using it requires a new purchase, or you can switch to the annual subscription (~$29.95/year) instead. Neither path is dishonest, but "lifetime" doesn't mean what a lot of buyers assume it means. On top of that, the new AI features added in 2026 are reserved for subscribers, or sold as a paid add-on if you're on the one-time license — so the version of eM Client with AI built in is, in practice, the subscription version.
The Mac Version Still Lags Behind Windows
eM Client has historically built for Windows first, with the Mac app catching up to feature parity over time rather than launching even. That gap has narrowed over the years, but for users specifically comparing the two platforms side by side, the Windows version is still generally considered the more complete experience.
AI Arrived in 2026 — But Only as ChatGPT, and Only If You Pay More
eM Client Pro added generative AI in April 2026: drafting replies, summarizing long threads, rewriting tone, and translation — all powered by ChatGPT specifically. There's no choice of model, no local option, and no bring-your-own-key flexibility — it's ChatGPT or nothing, and it's only available on the subscription license or as an add-on purchase for the one-time license. If you specifically want AI you can choose the provider for — including a free local model — eM Client's 2026 AI update doesn't get you there.
The Best eM Client Alternatives in 2026
Saymail — BYOLLM AI, One-Time €29.99, Truly Cross-Platform
Saymail scores every email by importance instead of just helping you draft replies — a different category of AI than eM Client's generative tools, closer to automatic triage than a writing assistant. You choose what powers it: a free local model, your own API key from OpenAI, Anthropic, or Google, or pay-as-you-go Saymail Cloud credits. It's €29.99 once, covers Windows, macOS, and Linux equally (no "Mac version lags behind" problem, because there's one codebase across all three), and includes all future updates — no separate purchase required when the next major version ships. The trade-off, stated plainly: no calendar, no contacts manager, no tasks. If those are why you chose eM Client in the first place, keep reading — Saymail isn't a replacement for that part of the workflow.
Thunderbird — Free, Open-Source, No AI
Thunderbird remains genuinely free, cross-platform (Windows, Mac, Linux), and includes a built-in calendar — the feature eM Client switchers often miss most. There's no AI built into the core app, and Mozilla's own stated plan is to keep it that way, with any future native AI arriving as a paid add-on rather than in the free base. A reasonable landing spot if AI isn't actually the priority and you just want calendar-plus-inbox for nothing.
Mailbird — Windows-First, Lifetime License Option
Mailbird's lifetime "Pay Once" license has historically been Windows-only, but the company launched a Mac app via the App Store in September 2025, so one license now genuinely covers both platforms. Worth checking the fine print before you buy, though: the lifetime license covers your current version, and getting all future major and minor updates requires a separate "Lifetime Updates" add-on rather than being included by default — similar in spirit to eM Client's version-locked perpetual license, just structured slightly differently.
Spark — Subscription, Cross-Platform, Team-Focused
Spark's free tier is solid, and the paid plans (from $4.99/month) add AI compose, rephrase, and translate tools along with shared inboxes for teams. It's a strong pick if collaboration matters more than owning the software outright — but it's subscription-only, with no one-time purchase option at any tier.
eM Client vs. Saymail — Feature Comparison
| Client | Price / model | AI features | Calendar | Contacts | Privacy / local storage | Platforms |
|---|---|---|---|---|---|---|
| eM Client | Free (limited) / ~$59.95 once (current version) or ~$29.95/yr | ChatGPT drafting/summaries — subscription or paid add-on only | Yes, built-in | Yes, built-in | Local storage; AI requests go to ChatGPT when used | Win, Mac |
| Saymail | €29.99 once, all updates included | AI importance scoring + classification, BYOLLM (your provider or free local) | ✗ No | ✗ No | Local SQLite cache; BYOLLM keeps data with your chosen provider; CASA Tier 2 assessed | Win, Mac, Linux |
Said plainly: Saymail has no calendar or contacts manager — for users who need those, eM Client (or Thunderbird, for free) is the better choice. This isn't a footnote; it's a real limitation, and we'd rather you know it now than after you've bought a license.
Who Should Pick Saymail Over eM Client?
If you want AI importance scoring with your own API key → Saymail
You're not locked into ChatGPT, you're not paying extra to unlock AI on top of a license you already bought, and you can run it on a free local model if you'd rather not pay for AI usage at all.
If calendar + tasks in one app is non-negotiable → Stay with eM Client or try Thunderbird
Neither Saymail nor any client in this list replaces a dedicated calendar app combined with email — if you need that combination specifically, eM Client does it natively, and Thunderbird does it for free.
How to Move from eM Client to Saymail
Exporting your accounts
You don't need to export anything from eM Client itself — your email lives on your provider's servers (Gmail, Outlook, or IMAP), not inside eM Client's local database in a format you'd need to migrate. The only thing worth checking beforehand is whether you have any local-only folders or rules configured in eM Client that aren't reflected on the server.
Adding them to Saymail
Connect the same Gmail, Outlook, or IMAP accounts directly in Saymail using your existing credentials. Mail syncs automatically from the server, so nothing needs to be manually transferred. Calendar entries and contacts stored inside eM Client don't carry over, since Saymail has no equivalent modules — keep eM Client (or switch to a dedicated calendar app) for those if you need them.
