I Get "You Don't Have Permission to Interact With This Agent" When Emailing My Agent — Can External Users Email It?

The @gumloopagents.com inbox is restricted to Gumloop users who have the minimum read access to the agent. External users (people without Gumloop accounts) cannot email it. To build an email agent that anyone can contact, use a Gmail trigger on your own inbox instead.

Symptoms

• You send an email to your agent's @gumloopagents.com address and receive a reply saying You don't have permission to interact with this agent. Please request access from the agent owner.

• An external contact (customer, client, or anyone outside your Gumloop workspace) emails your agent and receives a reply saying You need a Gumloop account to interact with this agent. Please sign up at https://gumloop.com.

• You want to build a customer-facing email support agent (e.g., billing@yourcompany.com) but the @gumloopagents.com inbox blocks non-workspace senders.

Cause

The agent email inbox (@gumloopagents.com) works exactly like chatting with the agent inside Gumloop. Every incoming email goes through the same permission check: the sender's email address must match a Gumloop account, and that account must have read access to the agent. This is by design — it's an internal/workspace channel, not a public-facing one.

How to Fix It

Option 1: Grant the sender access (if they're a Gumloop user)

If the sender already has a Gumloop account, make sure their email matches the one on their Gumloop account, and share the agent with them.

1. Open your agent in Gumloop.

2. Click Share in the top-right corner.

3. Add the sender's email and grant them at least Viewer access.

4. Ask them to email the agent from the same email address that's on their Gumloop account.

Option 2: Use a Gmail trigger for external/customer-facing email (recommended)

If you want anyone — including people without Gumloop accounts — to email your agent, skip the @gumloopagents.com inbox entirely. Instead, connect your own email inbox and use a Gmail trigger.

1. Connect your email account (e.g., billing@yourcompany.com) via the Gmail integration in Settings → Apps.

2. Open your agent and go to Triggers.

3. Add a Gmail “new email” trigger pointed at that inbox.

4. Anyone can now email that address. Each new email fires the agent, and the agent can reply through the same Gmail thread using the Gmail tool.

This pattern works because the Gmail trigger reads the inbox using your Gmail credentials — there's no per-sender Gumloop account or permission check involved.
