SparkMail

0.5.0

SparkMail is a free mail client for macOS: smart inbox, snooze, autopilot rules, calendar, meeting notes and PGP — with an AI assistant on your own model. No subscription, no ads, no cloud.

A personal mail client with a smart inbox, snooze, autopilot rules and an AI assistant on your own model. No subscription, no ads, no cloud in between.

Who is waiting for your answer, which meetings are left today, what comes back from snooze — before you dive into the inbox.

Features

Your own model

Summaries, smart drafts, translation, phishing checks and an agent that searches your mail — through Ollama, LM Studio, llama.cpp or any OpenAI-compatible server you run.

Autopilot

Rules in plain words

Write “archive GitHub notifications about closed issues” and the AI builds the rule. Every action lands in a log you can read.

Focus

Snooze, pin, set aside

Send a message back to later, keep the important ones pinned, set things aside without losing sight of them. Undo with Z.

Privacy

Trackers stripped

Remote images blocked, tracking pixels cut out, no telemetry. The app talks only to your mail servers and your AI.

Calendar

Meetings and notes

macOS Calendar next to your mail, invitations answered in one click, meetings recorded and transcribed on this Mac with whisper.cpp.

Security

PGP built in

OpenPGP encryption and signatures, keys found by WKD, decrypted mail never written to disk. Passwords stay in the macOS keychain.

Installation

1
Download and drag
Open the DMG and drag SparkMail to Applications.
2
Confirm the first launch
SparkMail is signed by IBCSC but not notarized by Apple. On first launch open System Settings → Privacy & Security and click “Open Anyway”.

Any IMAP/SMTP account: Gmail and iCloud with an app password, Outlook, Fastmail or your own domain. AI is optional — point it to Ollama in Settings → AI.

Questions and answers

Is it really free?

Yes. SparkMail is made by IBCSC, a Belgian non-profit for citizen cybersecurity. There is no subscription, no ads and no premium tier.

Where does my mail go?

Straight between your Mac and your mail server. Nothing passes through IBCSC or any third-party cloud; mail is cached in a local database on your Mac.

Do I need an AI model?

No. Everything works without AI. With a local model (Ollama, LM Studio, llama.cpp) you get summaries, drafts, translation and the mail agent — still without leaving your network.

Why does macOS warn me on first launch?

The app is signed with the IBCSC certificate but not notarized by Apple. Confirm once in System Settings → Privacy & Security → Open Anyway.

Which languages does it speak?

English, French, Dutch, German, Spanish and Russian. It follows macOS by default; change it in Settings → General.

Intel Macs, Windows, iPhone?

For now SparkMail runs on Macs with Apple Silicon (M1 and later), macOS 13 or newer.
