Its own address
Each agent gets an address of its own, apart from your team's mailboxes. All it can read is mail sent to that address.
Agent Lab Channel SDK · Agent Email
An email inbox
for your AI agent.
Give your AI agent a dedicated email address. It can receive customer and supplier emails, reply in the same thread, and keep a record of each exchange.

> Anything in the support inbox I should look at today?
12 came in. I've answered 9 — six order questions and three address changes — each in its original thread.
3 need you: two refunds and one partnership invitation. I put a summary at the top of each.
> Reply to the partnership one: next Tuesday afternoon works
Done — replied in the same thread and noted the time.
Why an agent needs its own inbox
Agents can send email.
Nobody reads the replies.
A lot of work still runs on email: customers answer order confirmations, suppliers send quotes, partners reply with meeting times.
To let an AI agent handle that today, you either lend it one person's Gmail access or use a sending service that can't receive. The first gives it far too much and breaks when that person leaves; the second sends fine, but the replies land where no one is looking.
Today
- The agent borrows one person's mailbox and sees all of their mail
- A sending service only sends; replies go to some other inbox
- Someone forwards replies to the agent by hand, and threads break
With Agent Email
- Each agent has its own address and sees only mail sent to it
- Your agent hears about new mail as it arrives
- Replies join the original thread, and every exchange is kept
Three things
Let an agent handle email without borrowing anyone's account.
Receive and reply in one thread
Your agent hears about new mail; its reply joins the original thread, so the customer sees an ordinary conversation.
Everything on record
What came in, what went out and when: all of it can be looked up, so a person can take over at any point.
Good first jobs
Start with the mail that follows a pattern.
Mail with steady content and clear rules is the easiest to hand to an agent first.
Support inbox
Sort the mail, answer the common questions, pass the hard ones to a person.
Orders and bookings
Customers reply to a confirmation to change a time or address; the agent checks and answers.
Suppliers and partners
Quotes, delivery dates, reconciliations: the agent gathers the details before it replies.
Internal requests
Expense claims and access requests from colleagues: the agent checks the form and fills the gaps.
For developers and AI agents
Connects like the Channel SDK's other channels.
MCP tools and an HTTP API, as for the LINE channel.
MCP and HTTP API
AI tools such as Claude Code, Codex and Cursor use MCP; your own code calls the HTTP API.
New mail pushed to you
When mail reaches the agent's address, your service is told, with no inbox to keep checking.
You set the limits
Which mail the agent may answer on its own and which a person sees first is agreed when we open it.

FAQ
Before you start
What is Agent Email?
Agent Email is the email channel of Crescendo Agent Lab's Channel SDK. It gives an AI agent an email address of its own: it receives mail and replies in the original thread. You can create an Agent Lab workspace for free.
How do I start?
Create a free Agent Lab workspace. Use the form to discuss email setup, receiving on your domain, or volume pricing.
Can my AI agent receive email and reply in the same thread?
Agent Email gives the agent a dedicated inbox for incoming messages and keeps its replies in the original thread.
How is it different from letting AI read my Gmail?
Reading someone's Gmail needs that person's access, the agent sees all of their mail, and it breaks when they leave. Agent Email gives the agent its own address, and it sees only mail sent there.
Can mail come in on our own domain?
Tell us which domain you'd like to receive on when you apply, and we'll explain what works in our reply.
How much does it cost?
Quoted by use and volume; we'll tell you after you apply.
Can an AI tool apply for me?
Yes. Have it read https://agentlab.cresclab.com/channels.md; it should ask you before it sends your name and email.
When a customer replies,
someone should pick it up, even if it's an agent.
