The key distinction

Transactional and marketing. They don't use the same route.

This is the single biggest thing to understand before you send. Get it wrong and your promos silently get blocked; get it right and both kinds of messages land reliably.

DND corridor

Transactional · receipts, loyalty, alerts

Reaches DND-registered customers.

Order confirmations, shipped alerts, loyalty balance updates, and appointment reminders all count as transactional. They route via the DND-compliant corridor and land on every Nigerian mobile number.

Starts at ₦4.00 per segment.

Generic route

Marketing · promos, discounts

Does not reach DND numbers.

Promos, discount codes, and "come back and shop" campaigns are marketing. They run on the generic route — which means DND-registered customers don't receive them. That's a carrier rule, not ours.

Starts at ₦2.50 per segment.

When to use SMS

Versus WhatsApp or email.

Three practical rules for deciding which channel a given message belongs on. Not defensive — just realistic about what each one is good at.

Reach everyone, not just app users

SMS lands on every mobile number in Nigeria — no app installed, no internet required. Email needs inbox access; WhatsApp needs the app open. For a service charge or a receipt, that's the difference between 70% and 99%.

Short and urgent

A queue is dissolving. A reminder needs to land in five minutes. SMS shows up on the lock screen within seconds. WhatsApp messages get buried in group threads; emails sit unread. Use SMS when the message matters today.

It needs to be opened

Industry open rates for SMS sit well above email. For payment nudges, appointment confirmations, and delivery pickups, that open rate is what pays back the cost per segment.

Nothing about this is new. It's the same reason banks still send OTPs over SMS — when reach and openability are the thing you're buying, this is still the channel.

Opt-in is your moat

The customers who said yes are the ones you keep.

Every marketing send requires recorded consent. Every STOP reply is honored automatically. Our preflight blocks any marketing dispatch that doesn't meet the opt-in threshold — not to slow you down, but to keep your sender ID from being reported and eventually revoked.

  • Capture consent at point of sale or signup — checkbox, signed form, or opt-in keyword.
  • Store the source, timestamp, and URL of consent against each contact.
  • Include a reply-STOP line in every marketing send. We honor STOP replies immediately.

Volume & cost

What retail operations typically spend.

Typical monthly volume

1,000 – 25,000 / month

Rate per segment

Blend of ₦2.50 & ₦4.00

Typical monthly spend

₦5,000 – ₦100,000

Retail is a mix — transactional on the DND corridor (₦4) for receipts and alerts, marketing on the generic route (₦2.50) for promos. The blend depends on how often you run campaigns.
