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.
Deliver OTPs, receipts, and transactional notifications without queue backpressure or artificial rate-limiting.
Brevo routes marketing blasts and transactional alerts on overlapping clusters. PhotonRelay runs dedicated transactional pipelines with sub-700ms delivery.
Never pay for unused monthly tier packages. If you send 20,000 emails, you pay only $7.50 on PhotonRelay (vs $18.00 on Brevo Starter).
Inspect raw SMTP server transcripts, bounce reasons, and delivery events for 30 days on all accounts with zero retention fees.
Automatic verification of SPF, 2048-bit DKIM keys, and DMARC alignment satisfies Google and Yahoo requirements straight out of the box.
Direct Indian rupee settlement (₹42/1k) with GST tax invoices, saving engineering teams international payment markups.
Talk directly with deliverability engineers rather than navigating generic CRM support tickets.
Zero code refactoring. PhotonRelay is 100% compliant with standard RFC 5321 SMTP on ports 587 and 465.
