IzoMailer
A clean, fast email app for Linux and Android. Unread mail stands out, new
mail arrives within seconds, and nothing passes through anyone else's
servers: your email goes only between your device and your mail provider.

This repository holds IzoMailer's downloads (Releases)
and its issue tracker. The source code is not public.
Download
Ubuntu, Debian, Linux Mint, Pop!_OS…: the APT repository (recommended)
Ubuntu 22.04 or newer, Debian 12 or newer, and distributions based on them.
Updates arrive with your normal system updates.
sudo curl -fsSLo /etc/apt/keyrings/koli-bg.gpg https://apt.koli-bg.com/KEY.gpg
echo "deb [signed-by=/etc/apt/keyrings/koli-bg.gpg] https://apt.koli-bg.com stable main" \
| sudo tee /etc/apt/sources.list.d/koli-bg.list
sudo apt update && sudo apt install izomailer
Fedora, openSUSE…: the .rpm
Download izomailer-<version>-1.x86_64.rpm from the
latest release, then:
sudo dnf install ./izomailer-*.x86_64.rpm # Fedora
sudo zypper install ./izomailer-*.x86_64.rpm # openSUSE
Any other distribution: the AppImage
Download IzoMailer-<version>-x86_64.AppImage from the
latest release, make
it executable and run it:
chmod +x IzoMailer-*-x86_64.AppImage
./IzoMailer-*-x86_64.AppImage
The AppImage doesn't update itself: download the new one from Releases.
All Linux builds need a 64-bit PC (x86_64) and glibc 2.35 or newer (any
distribution from 2022 on).
Android
Coming to Google Play.
Gmail
On Linux, add a Gmail account with Sign in with Google. Google shows
"Google hasn't verified this app" once: IzoMailer is a small independent
app that hasn't been through Google's (paid, yearly) verification. Choose
Advanced → Go to IzoMailer to continue. Google allows unverified apps a
limited number of users; if sign-in is refused, use an
app password instead (pick Gmail
in the sign-in dialog).
Tasks (optional)
IzoMailer can turn any email into a task, with a link back to the email, and
show your tasks by status next to your mail. It stays out of the way until you
connect it.
Tasks live at tasks.koli-bg.com, a small service
by the same person who makes IzoMailer, and it's free to use: sign in there,
create an API token, and paste it into IzoMailer under ⋯ → Tasks settings….
Workspaces can be shared with a few people (a free workspace holds up to 10
open tasks and 3 members).
