          "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.

Eight 'multiple services' full outages on the status page since July.\n\n**Postmark API + MCP.** 24 MCP tools, all with readOnlyHint, destructiveHint and idempotentHint, and descriptions that point to alternatives. No OpenAPI spec and no published request-rate limit.\n\n## Before you call either\n\n### Brevo API + MCP\n\n1. 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### Postmark API + MCP\n\n1. Install @activecampaign/postmark-mcp, never the unscoped postmark-mcp package\n2. Use the token `POSTMARK_API_TEST` to check a payload without sending\n3. Set `MessageStream` to `outbound` for transactional mail and a broadcast stream for bulk\n4. Set `WEBHOOK_URL_ALLOWLIST` so a misled createWebhook call can't send events to someone else's server\n5. Keep `count + offset` under 10,000 on message and bounce searches\n\n## Other comparisons with Brevo API + MCP or Postmark API + MCP\n\n- [Amazon SES vs Brevo API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-brevo.md)\n- [Amazon SES vs Postmark API + MCP](https://www.anchorterminal.com/compare/amazon-ses-vs-postmark.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 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 Postmark API + MCP](https://www.anchorterminal.com/compare/loops-vs-postmark.md)\n- [Mailgun API + MCP vs Postmark API + MCP](https://www.anchorterminal.com/compare/mailgun-vs-postmark.md)\n- [Mailjet API + MCP vs Postmark API + MCP](https://www.anchorterminal.com/compare/mailjet-vs-postmark.md)\n- [Postmark API + MCP vs Resend API + MCP](https://www.anchorterminal.com/compare/postmark-vs-resend.md)\n- [Postmark API + MCP vs Twilio SendGrid](https://www.anchorterminal.com/compare/postmark-vs-sendgrid.md)\n- [Postmark API + MCP vs SMTP2GO API + MCP](https://www.anchorterminal.com/compare/postmark-vs-smtp2go.md)\n",
