We Just Sent Our 100,000th Message

Last month, Sendexa crossed 100,000 messages delivered. Here is what the journey to get here actually looked like.

In April 2026, Sendexa delivered its 100,000th message.

I want to write about what that number actually means — not in a press-release way, but honestly. Because the road to 100k was not a straight line, and I think the real story is more useful than a celebration post.

Where We Started

When we started Sendexa, the goal was simple: give African businesses a reliable, developer-friendly way to communicate with their customers. SMS, OTP, WhatsApp — the channels that actually reach people in Ghana and across the continent.

The first few hundred messages we sent were tests. Our own tests. We were debugging delivery, chasing down carrier issues, making sure the platform worked before we let anyone else near it.

Then came the first real customers — businesses willing to trust us with something as critical as their OTP flows and transaction alerts. That trust is not something you take lightly when you are building communications infrastructure. A failed OTP means a user locked out of their account. A delayed transaction alert means a confused customer calling support. The stakes were clear from day one.

What 100,000 Messages Actually Looks Like

100,000 messages is not just a number. It is:

• Thousands of OTPs delivered so users could verify their accounts and get back to what they were doing
• Transaction alerts reaching customers in seconds so they knew their money was safe
• Businesses communicating with their customers across MTN, Telecel, and AirtelTigo networks
• Every single one of those interactions depending on our infrastructure not failing

We did not get here perfectly. There were carrier issues we had to fight through, edge cases in delivery that took days to track down, and moments where we had to make hard calls about what to prioritise. That is the unglamorous reality of building infrastructure.

What We Learned

The biggest thing we learned on the way to 100k is that reliability is not a feature — it is the product. Businesses do not talk about your API documentation or your dashboard design when things are working. They only talk about those things when something breaks.

So we obsessed over delivery rates. We obsessed over latency. We built monitoring before we built marketing. Every improvement we made to the platform came from watching real message delivery data and asking: where is the failure? Where is the delay? Fix that first.

"The businesses that trusted us early — when we were small and unproven — are the reason we are here. We do not forget that."

Where We Go From Here

100,000 is a waypoint, not a destination. We are still early. The opportunity in front of us — helping African businesses communicate reliably with their customers — is enormous, and we have barely started.

What I can promise is that everything we are building next is grounded in the same principle that got us to 100k: make it work, make it reliable, and make it accessible to developers and businesses across the continent.

The next milestone is already in sight. Thank you for being part of this.
