ChatGPT + Brevo: What the Integration Can (and Can't) Do in 2026
There’s no official Brevo app in ChatGPT’s directory yet — but Brevo (ex-Sendinblue) runs its own hosted MCP server at mcp.brevo.com, and you can plug it into ChatGPT as a custom connector. The server, shipped as part of Brevo’s AI Lab push, exposes 27 modules: contacts, email/SMS/WhatsApp campaigns, CRM deals and tasks, templates, and analytics. Brevo’s own docs list Claude Desktop, Cursor, and VS Code as clients, but any MCP-capable client works — ChatGPT included. What you get is a session-bound assistant: it queries and acts on your Brevo account when you ask, and between chats nothing watches your contact events or campaign results.
Here’s what the ChatGPT Brevo integration actually does, how to wire it up, and what to use when you want marketing work that runs without you.
What ChatGPT can actually do with Brevo
- Pull campaign performance in plain English. “How did last week’s email campaigns do?” — opens, clicks, and unsubscribes answered from your real account data instead of a dashboard export.
- Manage contacts conversationally. Add a contact, update attributes, check which lists someone is on — the MCP server’s contact modules handle create, update, and lookup.
- Work across Brevo’s whole surface. Because Brevo bundles marketing and CRM, the same connector reaches deals, tasks, and companies — “which deals touched contacts from the spring campaign?” is one question, not two tools.
- Draft campaign and template copy with live context. Ask ChatGPT to draft a re-engagement email informed by the actual performance of your last three sends, then create it as a template in Brevo.
- Run inside agent sessions. With ChatGPT Work (launched July 9, 2026), you can @-mention connected apps and let an agent work across Brevo and the rest of your stack in a long, metered run — a quarterly list-health audit, say. Still a run you start.
How to set it up
- In Brevo, go to Account → SMTP & API → API Keys and generate an MCP token. Treat it like a password.
- In ChatGPT, open Settings → Connectors → Advanced and enable Developer Mode (custom connectors need a paid plan).
- Create a new connector named Brevo, point it at
https://mcp.brevo.com, and supply your token as the Bearer authorization header. - Start a chat, add Brevo as a source, and ask something concrete: “list my three most-clicked campaigns this quarter.”
The limits that actually matter
- It doesn’t run on triggers. There’s no “when a campaign finishes, do X” or “when a contact hits a lead score, alert sales.” ChatGPT touches Brevo when you prompt it — it never fires on a Brevo event. (Brevo’s native automations still run; ChatGPT just isn’t part of them.)
- No official app means more setup and less polish. You’re in custom-connector territory: developer mode, a token you manage yourself, and no vendor-tuned prompts. Fine for a technical marketer, a hurdle for everyone else.
- Session-bound, even in agent mode. ChatGPT Work runs are long and autonomous but manually started and metered against your plan’s allowance — an errand, not a standing watch on your list.
- Cross-stack follow-through stops at the chat. The connector won’t take what it found and email your team, update a spreadsheet, or file tasks on a schedule.
If you want Brevo work that runs on its own: Carly
The moment you want something to happen off a marketing event — a Monday-morning digest of last week’s Brevo sends, a hot contact synced to your CRM the second they cross a score threshold, a flag when a transactional template’s bounce rate climbs — you’ve crossed past what a chat connector is for.
That’s where Carly fits. Carly is an AI executive assistant that acts on triggers across your whole stack, set up by conversation instead of code:
- Fires on events and schedules, 24/7, in the cloud. Campaign wraps, threshold crossed, Monday 8am — Carly acts without a chat open.
- No-code setup. Tell Carly “every Monday, pull last week’s Brevo numbers and email the team a digest” in plain English; it interviews you and builds the workflow.
- Connects marketing to the rest of your work — Brevo data flowing into email, CRM, tasks, and spreadsheets in one flow.
- Actually sends — drafts and sends email across Gmail and Outlook, updates your CRM, manages tasks.
- Connects to anything — 200+ native integrations, plus any other tool via your own API key.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. See integrations — and Carly natively integrates with Brevo.

Frequently Asked Questions
Does ChatGPT work with Brevo?
Yes, via Brevo’s official hosted MCP server at mcp.brevo.com — there’s no Brevo app in ChatGPT’s directory yet, so you add it as a custom connector in developer mode. Generate an MCP token under Account → SMTP & API → API Keys, connect, and you can query and manage contacts, campaigns, and CRM data in plain English.
Can ChatGPT send Brevo campaigns?
The MCP server exposes campaign modules across email, SMS, and WhatsApp, so ChatGPT can create and work with campaigns you then review — but treat sending as something you confirm in Brevo, not something to fire blind from a chat. ChatGPT also can’t schedule recurring sends or react to results on its own.
Can ChatGPT react to a Brevo event automatically?
No. ChatGPT queries Brevo inside a session you start — it doesn’t watch for campaign completions, list growth, or lead-score changes. For “when X happens in Brevo, do Y across my stack,” you need a trigger-based assistant like Carly.
How do I connect ChatGPT to Brevo?
Generate an MCP token in Brevo (Account → SMTP & API → API Keys), then in ChatGPT open Settings → Connectors → Advanced, enable Developer Mode, and add https://mcp.brevo.com as a custom connector with your token as the Bearer header. Then ask about your campaigns or contacts directly in chat.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
