          "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).

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. A cross-tenant breach with customer contacts taken, weighed like the 14 September incident and decayed for the same-day fix, the write-up and direct notice to customers, -6 (https://status.brevo.com/incidents/01M266V1CZKJQNGZRNEGFD5CQE/write-up)",

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### Loops API + MCP\n\n1. Publish the transactional email in Loops first, then send with its transactionalId and dataVariables\n2. Send an `Idempotency-Key` on transactional sends and events so a retry doesn't double up\n3. On 429, back off exponentially and read x-ratelimit-remaining\n4. Ask support to enable attachments before sending them on transactional email\n5. Use events to trigger workflows instead of sending sequences yourself\n\n## Other comparisons with Brevo API + MCP or Loops API + MCP\n\n- [Amazon SES vs Brevo API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-brevo.md)\n- [Amazon SES vs Loops API + MCP](https://www.anchorterminal.com/compare/amazon-ses-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- [Brevo API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/brevo-vs-smtp2go.md)\n- [Loops API + MCP vs Mailgun API + MCP](https://www.anchorterminal.com/compare/loops-vs-mailgun.md)\n- [Loops API + MCP vs Mailjet API + MCP](https://www.anchorterminal.com/compare/loops-vs-mailjet.md)\n- [Loops API + MCP vs Postmark API + MCP](https://www.anchorterminal.com/compare/loops-vs-postmark.md)\n- [Loops API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/loops-vs-resend.md)\n- [Loops API + MCP vs Twilio SendGrid](https://www.anchorterminal.com/compare/loops-vs-sendgrid.md)\n- [Loops API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/loops-vs-smtp2go.md)\n",
