Email is slowing your team down
Your team works in Slack. But email sits in a separate tab, and things fall through the cracks.
Tab juggling
You flip between Gmail and Slack dozens of times a day. Every switch breaks your focus and slows your team down.
Emails get buried
Nobody knows if that support email was handled. It sits in one person's inbox while the rest of the team is blind.
Slow replies
Customers wait while your team figures out who should respond. By the time someone replies, the moment has passed.
Zero visibility
You can't see email status without asking. No dashboard, no assignments, no way to know what's open or overdue.
Every email, right where your team works
Emails arrive in Slack as rich messages. Your team discusses and replies in threads. The customer sees a normal email reply.
Everything in one place
Emails land in the Slack channel your team already watches. No tab switching, no context loss.
Every email tracked
Assigned, resolved, or pending. Every email's status is visible to the whole team in real time.
Reply in seconds
Type in the Slack thread. MailFellow sends it as a real email from your address. The customer never knows the difference.
Full visibility
Dashboard shows every email's status across all channels. Know what's open, who's handling it, and how fast you're replying.
Built for teams that run on Slack
Purpose-built for teams that run their business from Slack.
Emails appear in channels
Every incoming email is posted to the Slack channel you choose. Subject, sender, preview text, and attachments are all visible at a glance. Route different addresses to different channels for clean separation.
Reply from threads
Type your response in the Slack thread and MailFellow sends it as a real email. The recipient sees a normal message from your address. No forwarding headers, no bot signatures.
Interactive buttons
Each email comes with action buttons: resolve, assign to a teammate, block the sender, or mark as spam. One click and you are done. No need to type commands or open another app.
Slash commands
Use slash commands to manage your inbox right from Slack. Check status, list open emails, configure routing rules, and access settings without leaving the conversation.
Channel routing
Route multiple email addresses to multiple channels. Support goes to #support, sales to #sales. Each channel gets only the emails that belong there.
Clean formatting
Emails are displayed as clean Slack message blocks. No noisy link previews, no unfurl clutter. Just the sender, subject, body preview, and action buttons. Formatted for readability.
How it works
Connect your email, pick a channel, and start receiving. Takes about two minutes.

Read and reply
