          "2026-09-14. A Cloudflare API key with full account permissions, stored in Brevo's source code, let an attacker inject a ClickFix script for 5 hours 29 minutes, showing fake verification pages that pushed visitors to run malware. The post-mortem names brevo.com, sendinblue.com, the login, account, my and onboarding subdomains of brevo.com, sibforms.com and three embedded scripts (the Brevo forms script, the Conversations widget and the SDK loader) as affected. Brevo says app.brevo.com, the API and customer data weren't touched, and it published the fix (scoped, short-lived tokens and alerting).

          "2026-09-10. An attacker created a Brevo account, turned on SAML SSO and invited real users into it, and a scoping flaw then gave the attacker every organisation those users could reach. Brevo's write-up counts 138 accounts accessed, 6 used to send phishing, 43 with contacts exported and 93 with no meaningful activity. Brevo closed the route and ended every user session by 08:30 UTC, two hours after spotting it, disabled the links in the phishing emails, said it was deploying a fix that limits SSO to the organisation that owns the configuration, and is contacting each affected customer.

Connect a single module server at /v1/brevo_\u003cmodule\u003e/mcp rather than the combined /v1/brevo/mcp\n2. Send with POST /v3/smtp/email and the `api-key` header, not Bearer\n3. Use webhooks for delivery events. GET /v3/smtp/emails allows 2 requests a second\n4. Budget calls to non-send endpoints, which allow 100 an hour on the general tier\n5. Wait for account approval before counting on the free plan's 300 a day\n\n### SMTP2GO API + MCP\n\n1. Give the MCP a key limited to /email/send and the view endpoints it needs, since execute-request can call anything the key allows\n2. Send the key in the `X-Smtp2go-Api-Key` header or as Bearer, not in the JSON body, so it stays out of request logs\n3. Verify a sender domain first. Free accounts without one are held to 25 emails an hour\n4. On 429, pause until calls return 200 again. Repeated errors time out your IP for at least a minute\n5. Check smtp2gostatus.com before blaming your payload for mail stuck as 'processed'\n\n## Other comparisons with Brevo API + MCP or SMTP2GO API + MCP\n\n- [Amazon SES vs Brevo API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-brevo.md)\n- [Amazon SES vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-smtp2go.md)\n- [Brevo API + MCP vs Loops API + MCP](https://www.anchorterminal.com/compare/brevo-vs-loops.md)\n- [Brevo API + MCP vs Mailgun API + MCP](https://www.anchorterminal.com/compare/brevo-vs-mailgun.md)\n- [Brevo API + MCP vs Mailjet API + MCP](https://www.anchorterminal.com/compare/brevo-vs-mailjet.md)\n- [Brevo API + MCP vs Postmark API + MCP](https://www.anchorterminal.com/compare/brevo-vs-postmark.md)\n- [Brevo API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/brevo-vs-resend.md)\n- [Brevo API + MCP vs Twilio SendGrid](https://www.anchorterminal.com/compare/brevo-vs-sendgrid.md)\n- [Loops API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/loops-vs-smtp2go.md)\n- [Mailgun API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/mailgun-vs-smtp2go.md)\n- [Mailjet API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/mailjet-vs-smtp2go.md)\n- [Postmark API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/postmark-vs-smtp2go.md)\n- [Resend API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/resend-vs-smtp2go.md)\n- [Twilio SendGrid vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/sendgrid-vs-smtp2go.md)\n",
