Features

Built for how Nigerian fintech
actually works.

Not a checklist of features you'll never use. The things that keep your users safe, informed, and coming back.

OTP & verification email
Login codes, 2FA, phone verification — delivered under 400ms with 96% inbox placement. Every delayed OTP is a customer who churns at the authentication step.
Transaction receipts
The most-opened email your product sends. Make it count — branded, instant, and always in the inbox. Not the spam folder.
Fraud & security alerts
Real-time security notifications that reach customers the moment something suspicious happens. Speed and deliverability are not optional here.
Lifecycle automation
Onboard new users, re-engage dormant accounts, upsell products at the right moment — all triggered by real behaviour across email, SMS, and push.
Naira billing
Every message billed in Naira. No dollar card, no FX volatility eating into your unit economics. Predictable costs your finance team can plan around.
REST API
Integrate transactional messaging in an afternoon. Full documentation, Nigerian-optimised infrastructure, 99% uptime SLA.
Workflows

The messages that

Onboarding flow

From sign-up to first transaction.

The first 72 hours determine whether a new user activates or disappears. A well-timed sequence across email and SMS closes that gap.

Re-engagement flow

Bring dormant users back before they leave.

Users who haven't transacted in 30 days are one well-timed message away from churning permanently — or returning.
