Sendchamp

Sendchamp is a Nigerian-founded multi-channel customer messaging platform providing a unified API for SMS, WhatsApp Business, voice OTP, and email — built specifically for Nigerian and African market conditions, with NGN pricing, Nigerian carrier-optimized SMS delivery, DND bypass for transactional messages, and WhatsApp Business API access in a single developer-friendly platform. Sendchamp is one of the few platforms that natively combines all the messaging channels Nigerian businesses actually use — SMS for broad reach, WhatsApp for engagement, voice OTP for reliability — in one product built by a team that understands Nigerian telecommunications deeply. The SMS API delivers messages to all four Nigerian mobile networks (MTN, Airtel, Glo, 9mobile) with competitive NGN pricing, making it economically attractive for Nigerian businesses that previously found dollar-denominated global SMS platforms expensive at scale. Transactional messages use DND-bypass routes compliant with NCC regulations, ensuring OTPs, bank notifications, and health alerts reach all recipients. Promotional messages respect DND opt-outs. The same API key handles both routing scenarios, with the message type parameter determining which route is used. WhatsApp Business API through Sendchamp gives Nigerian businesses access to the Meta WhatsApp Business Platform with Sendchamp managing the business verification and API onboarding process. This is Sendchamp's most differentiated feature for the Nigerian market: WhatsApp has extraordinary penetration in Nigeria with almost universal usage among smartphone users, making WhatsApp the highest-engagement channel for customer communication. Sendchamp's WhatsApp API supports template messages (one-way notifications sent outside of conversation windows), session messages (customer service replies within 24-hour conversation windows), and interactive messages with buttons and list menus that drive user actions within WhatsApp. Voice OTP provides phone call verification as an alternative or fallback to SMS OTP. Sendchamp's voice OTP calls the recipient's number and reads the code using text-to-speech — a critical fallback for reaching Nigerian users on DND, users in areas with poor SMS delivery, or users who prefer call verification. Sendchamp's automatic OTP retry logic can fall back from SMS to voice after a configurable timeout, ensuring maximum verification success rates for Nigerian apps handling user authentication. Email delivery through Sendchamp provides transactional email delivery for Nigerian applications — account verification emails, password resets, order confirmations, and receipt delivery. Sendchamp manages email sending infrastructure including SPF/DKIM setup, IP reputation management, and bounce handling, so Nigerian developers focus on email content rather than email deliverability engineering. The Sendchamp dashboard provides a unified view of all channel analytics — SMS delivery rates, WhatsApp message read rates, email open rates, voice call success rates — giving Nigerian marketing and product teams a consolidated view of customer communication performance across all channels. Sendchamp pricing uses a freemium model with a free tier providing limited monthly messages to allow Nigerian startups to build and test without upfront costs. Paid plans are priced in NGN with pricing tiers based on monthly message volume, scaling affordably from startup to enterprise. The combination of Nigerian-native understanding, multi-channel API in one platform, and NGN pricing makes Sendchamp one of the top choices for Nigerian businesses building customer communication infrastructure.
