Brevo MCP in Claude and ChatGPT: email marketing, contacts and campaigns from a conversation

Brevo MCP lets Claude or ChatGPT work with your Brevo email marketing: look at contacts and lists, read campaign results, draft campaigns and templates, and send tests, from a conversation. Brevo hosts an MCP server, and Fezola relays it: you create an API key with the MCP option in Brevo, paste it once in Fezola, and give each assistant a single connector. Facts below come from Fezola's code and from the tools Brevo's server lists as of 14 November 2026: they can change, so check the connectors page.

What you can ask

• "How did my last email campaign perform?"
• "List the contacts added to my newsletter list this month."
• "Draft a new campaign from this template and send me a test."
• "Which templates do I have for transactional emails?"
• "Show my verified senders and domains."

Brevo's server covers contacts, lists and segments, email campaigns, templates, SMS campaigns, senders and domains, and campaign reports. The exact tools belong to Brevo, so Fezola does not freeze them in a list: your assistant searches for the tool that fits your request, then calls it.

How to connect it

1. In Brevo, create an API key with the MCP option, under SMTP & API, API Keys.
2. In the Fezola app, open Sources, add Brevo and paste the key. It is stored encrypted.
3. Connect Fezola to your assistant once, at https://api.fezola.com/mcp: see how to add a custom connector to Claude. ChatGPT custom connectors are available on Business, Enterprise and Edu plans.

Guardrails

• Campaigns change what people receive. Keep your assistant's approval prompts on before it creates, edits or sends anything, and use a test send first.
• A key you can revoke. Revoke the API key in Brevo to cut access at any time.
• Third-party text is data. What Brevo returns, such as a contact field, is data and never instructions.
• Only what you tick. You can hide Brevo from an assistant: see choose which tools Claude or ChatGPT can see.
• Your plan applies. Brevo's own plan and limits apply.

Several accounts

Agencies often keep one Brevo account per client. In Fezola each account is its own source with its own key, and one assistant can work across them, as with several Google Ads accounts.
