Marketplace listing

We’ve been using your platform for a while and believe our product could be a strong fit for your marketplace. Many of our customers already work with tools in your ecosystem, and we think a listing would make it easier for shared users to discover, connect, and benefit from both products together.

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.

    No Dashboard

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.

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.

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.

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.

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.

Route multiple email addresses to multiple channels. Support goes to #support, sales to #sales. Each channel gets only the emails that belong there.
