Email, reimagined Looks like Slack

Email that finally feels like chat

Woof looks and feels like Slack channels, threads, reactions, real-time messaging but it's all email behind the scenes. Your team gets the speed of chat. Everyone else sees a normal email.

Communication is broken

Your team uses Slack for speed, but the rest of the world still runs on email. You end up managing both, and losing context in between.
Email is stuck in 1998

Email is stuck in 1998

Folders, flags, and unread counts. The email UI hasn't evolved while the rest of communication moved to real-time chat.

Chat tools are walled gardens

Chat tools are walled gardens

Slack and Teams only work if everyone's on the same platform. External communication still falls back to email anyway.

Context is scattered

Context is scattered

Half your conversations are in Slack, half in email. Important decisions get lost between platforms. One source of truth doesn't exist.

Chat speed, email reach

Woof gives your team the real-time, channel-based experience of Slack — but every message is an email. External people don't need to install anything. Internal people never touch a clunky inbox again.

Everything you'd expect from modern chat

Channels, threads, reactions, presence all the features that make Slack great, built on email so it works with everyone.
Channels over folders

Channels over folders

Organize conversations by topic, project, or team. Each channel maps to a mailing list or shared label behind the scenes.

Threads that make sense

Threads that make sense

Reply in-thread and it becomes an email thread. No more losing context across 47 disconnected forwards.

Works with everyone

Works with everyone

Message anyone with an email address. They see a normal email. You see it in your channel. No sign-up wall for external contacts.

Real-time delivery

Real-time delivery

Messages appear instantly for Woof users. Falls back to standard email delivery for external recipients. Best of both worlds.

Reactions & presence

Reactions & presence

React with emoji, see who's online, get typing indicators. All the chat UX you love, mapped onto email metadata.

Your inbox, your rules

Your inbox, your rules

Bring any email account. Gmail, Outlook, Fastmail, self-hosted. Woof layers on top without replacing anything.

What your recipient sees: a normal email

You send from a Slack-like interface. They receive a perfectly formatted email in Gmail, Outlook, or wherever they read mail.
