Thanks,

Connects to the email you already have
Zackem is not an email service. We never receive, store or read your messages. Your mail stays where it always was — with your email provider — and a copy is kept on your own computer so it opens instantly.
Microsoft, Google, Yahoo, Apple or your company's mail server.
Mail, passwords and settings stored on your computer, encrypted by Windows or the Mac Keychain.
Not in the path. Your mail never touches them.
Sign-in tokens and app passwords are locked in your computer's own protected storage — Windows Credential Manager or the Mac Keychain — never sent to us.
Replies, drafts and suggestions wait for you. Zackem only sends when you press Send.
AI is off until you choose it — and you can run it entirely on your own computer.
Deleting an account erases its local copy from your computer completely.
See all accounts together or one at a time, each with its own color. Duplicates sent to several of your addresses show once.
Real people in Focused, newsletters and notifications in Other. Move a sender once and Zackem remembers.
Every mailing list in one screen, with how often each one writes. Unsubscribe, block, or clear out the old mail in a click.
Search every account at once, even offline, because your mail is stored on your computer.
One morning view: today's calendar, the emails waiting for your reply, and reminders that are due.
Built from the ground up for every language, including full right-to-left support for Hebrew, Yiddish and Arabic.
Zackem can mark what needs a reply, summarize long threads, find dates and draft responses. You decide whether AI is used at all — and where it runs.
PrivacyNothing about your mail leaves your computer.
CostFree. This is how Zackem starts.
PrivacyA free AI model runs on your own computer. Nothing leaves it.
Good to knowWorks best on a recent computer with 16 GB of memory; Macs with Apple chips run it especially well.
PrivacyConnect your own Claude, ChatGPT or Gemini. Only the emails you ask about are sent to that service.
CostYou pay your AI provider directly. We add nothing.
The core app covers email. Modules add more, and you can switch them on at any time.
Your Microsoft, Google and iCloud calendars inside Zackem. Dates in your emails appear as tentative until you confirm them.
Zackem measures the time you spend reading and writing each email. Assign it to a client or case with one button and export it.
File emails and time straight into the systems you use, starting with Clio and growing from there.
Needs-reply alerts, reminders, summaries and drafts — using local AI or your own account.

No. Zackem has no email servers. Your mail stays with your email provider, and a copy is kept on your own computer. We never see it.
Microsoft 365, Exchange, Outlook.com, Gmail, Yahoo, iCloud, AOL, Zoho and nearly any account that supports standard IMAP, including mail on your own domain. Setup steps for each are in the Help pages.
At launch, Gmail connects with a Google app password: turn on 2-Step Verification in your Google account, create an app password, and paste it into Zackem once. See the step-by-step guide.
Yes. Zackem runs on Windows 10 and 11 and on macOS, on both Apple-chip and Intel Macs. One license works on either. Full system requirements.
Nothing is lost. Zackem keeps working as the free version with up to 2 accounts, and you can buy a license or a module at any time to unlock the rest.
Never. AI is off until you turn it on, and you choose whether it runs on your computer or through your own AI account.
It comes from the Yiddish tzuzamen — "all together." Every inbox, all together, in one place.
We're opening a small beta. Testers get a free license in exchange for honest feedback — especially if you use several email providers or work in Hebrew or Yiddish.
