Fintech products live or die on timely email. OTPs, receipts, and security alerts must arrive in seconds. Marketing promos must never share the same reputation lane.
Transactional email needs its own pipeline, searchable logs, and retry logic your backend can trust. Engineers need API keys, webhooks, and clear bounce codes. Support needs to trace a single message when a customer complains.
Nigerian users expect instant OTP delivery during transfers and signups. Slow or missing mail drives support tickets and abandoned transactions. Treat transactional uptime like payment uptime.
Template every alert type: password reset, debit notice, KYC update. Legal and compliance teams can review copy once instead of chasing one-off sends.
Run load tests before launch week. A spike in signups should not delay OTP delivery for existing users.
Ship product mail through transactional emails. Integrate with the developer API and wire webhooks for delivery events your systems can act on.
