Connecting Resend to AI: send it, then know for sure that it arrived
Resend can be connected to AI with a key from your own account. The assistant can send a message from your verified domain and afterwards check whether that message was actually delivered. It cannot do much more here, which is the point: there is no contact or list management in it. Sending cannot be undone and happens only on explicit request.
Send it, then know how it ended
Send a message
The assistant writes subject and content and sends the message to one or more recipients. That happens from an address on the domain you verified at Resend; any other sender address does not get through.
Replies reach a human
A message can carry a reply address, and colleagues can be put in copy. The recipient's answer then lands in a mailbox somebody actually watches, rather than at an address that only sends.
Keep kinds of messages apart
A send can carry a label, for instance to separate confirmations from reminders. That helps when you later want to see which kind of message went out when.
Check whether it was delivered
For a message the assistant sent itself, it can ask for the delivery status. It can therefore confirm that something arrived, instead of reporting that it was sent and hoping for the best.
Where a narrow mail connector is enough
Software development
- Situation
- A customer says the activation mail never arrived and the support team cannot verify that without a developer.
- What the agent does
- The assistant traces which message was sent and asks for the delivery status of that message.
- Result
- An unambiguous answer about that one message, without anyone diving into code or a dashboard.
Manufacturing
- Situation
- An order confirmation has to reach a buyer with the internal sales desk in copy, and that is done by hand from a mailbox today.
- What the agent does
- The assistant drafts the message from the order details, puts the sales desk in copy and presents it before it is sent.
- Result
- A confirmation that always looks the same, with the right people in copy.
Professional services
- Situation
- An adviser sends a short follow-up after every meeting, but in busy weeks it slips.
- What the agent does
- The assistant writes the follow-up from the notes and sends it only after approval, with the adviser's reply address on it.
- Result
- The client has something in writing the same day and can simply reply to a human.
E-commerce
- Situation
- A return request needs a message with instructions, and it matters that this message genuinely arrives.
- What the agent does
- The assistant sends the message and shortly afterwards checks whether delivery succeeded.
- Result
- A failed delivery is picked up straight away instead of when the customer calls again.
What you need to get started
-
1
Prepare the domain at Resend
Resend sends only from a domain verified in your account. You arrange that verification once at Resend itself, and without that step no message gets through.
-
2
Connect with your own key
The connector uses a key from your own Resend account. Your administrator can revoke it at any moment, which stops the connector immediately.
-
3
Agree who may have mail sent
Because there is little to do here, the setup conversation is mostly about who may ask for a send. You record that in the roles.
-
4
Putting it to work
From then on it runs through the conversation: somebody asks for a message and the assistant presents it. Every send and every status check stays traceable with its time and outcome.
A connector that genuinely sends post
Being able to send mail on behalf of your domain is a serious right, even when only two things are possible. That is why this connector is kept narrow and why nothing happens silently.
Where the data lives: Nederland of de EU
Only from your own domain
Sending works solely from the domain you verified at Resend. A message on behalf of some other domain does not get through.
No contacts, no lists
There is no way through this connector to request, create or list contact details. No address file can be pulled out of Resend along this route.
Show first, send after
A sent message cannot be withdrawn. The assistant therefore shows the recipient, the subject and the full text, and sends only when explicitly asked to.
Processing on your own server
What the assistant writes stays on our own server in the Netherlands, where open-weight models run. Message content does not travel to a model provider outside that environment and serves as training material nowhere.
What people want to know about Resend
Can I connect Resend to ChatGPT?
That would place a key able to send mail on behalf of your domain with a public service, without roles and without an audit log. IntraGPT holds that key inside your own environment, ties the send to roles you define yourself and keeps a record of every use. The model that writes the text runs on our own server.
Does IntraGPT work with Resend?
Yes. Resend sits in the catalogue as a working integration. The assistant can send a message and check the delivery status of a message it sent, using a key from your own Resend account.
Why does Resend refuse our sender address?
Nearly always because the domain is not verified yet, or because the sender address sits on a different domain than the verified one. Resend checks this on every send. The fix is not in the connector but in your Resend account: verify the domain and then use an address that sits on it.
How do I know a mail arrived?
You simply ask the assistant. For a message it sent itself, it can request the delivery status from Resend. That is different from a read receipt: it concerns whether the message was handed over to the receiving mail server. When there is doubt about a confirmation mail, this is the quickest way to be sure.
Can the assistant send a newsletter through Resend?
This connector is not made for that. It carries no list management and no way to assemble a group of recipients, so a newsletter would come down to loose messages without unsubscribe handling. Campaigns and lists belong in a marketing package, and those can be connected separately.
Is such a narrow connector not limiting?
For a marketing team it would be, for application mail it is not. If you only send confirmations and notifications, sending and checking is all you need. The advantage is that nothing can happen to contact details along this route, which keeps the agreements with the administrator simple. If you need more, you connect a package that offers it alongside.
What does a Resend connector cost?
The connector is part of the project we run together. Because there is little to configure the setup work is limited; the time mostly goes into the domain verification and into agreeing who may have mail sent. Usage at Resend itself runs through your own account there.
How long does setup take?
If the domain is already verified at Resend, the connector works quickly. If that verification still has to happen, it depends on how fast that is arranged on your side. After that one conversation remains about who may have mail sent.
