WHY DEVELOPERS SWITCH

Dedicated Transactional Speed. Zero CRM Bloat.

Brevo (formerly Sendinblue) has transformed into an all-in-one sales CRM and marketing automation platform. For backend engineers who only need high-speed SMTP relay for OTPs, receipts, and alerts, Brevo's daily rate-caps and bloated dashboard add unnecessary friction.

  • No 300/Day Cap • 5,000 free monthly emails unthrottled on day one.
  • Sub-700ms Median Delivery SLA with isolated Anycast MTA nodes.
  • Multi-Currency (USD & INR ₹42/1k) with GST tax credit invoices.
