Richmo is an enterprise-grade Bulk SMS Gateway focused on the Sri Lankan market, offering promotional SMS, transactional SMS, OTP verification codes, and SMS APIs for businesses. Its website positions it as a leading SMS gateway in Sri Lanka, highlighting direct carrier connectivity, real-time delivery reports, campaign management, Sender ID capabilities, and support for Unicode content such as Sinhala/Tamil.
In terms of channels, Richmo currently focuses mainly on SMS, including bulk messaging, OTP/Auth, REST API, and 2-Way Messaging. WhatsApp API and Number Lookup/HLR are marked as Coming Soon, so they should not yet be considered mature, production-ready capabilities. In terms of coverage, the brand and customer cases are clearly oriented toward Sri Lanka. Although the FAQ mentions global sending, the site does not provide a country list, international routing details, or pricing, so cross-border use cases require further confirmation. For performance, the website claims a 99.9% delivery rate, 99.9% Uptime SLA, 5ms average API latency, and throughput of 500+ messages/second for Target Campaigns, along with real-time delivery reports. These figures are suitable for scenarios where OTPs and campaign notifications require timely delivery, but they are still vendor-provided claims.
Richmo’s API design is relatively straightforward: it provides REST endpoints, Bearer Token authentication, and a simpler API Key parameter-based interface. The documentation includes cURL, PHP, and Python examples, and supports balance lookup. Pricing is relatively transparent: the User Account Portal has a one-time fee of Rs.5,000, SMS costs Rs.0.80/message with no monthly fee; Target SMS Campaign costs Rs.1.20/message; and the white-label reseller plan is Rs.75,000/year, with SMS costs available by contacting an account manager.
Its strengths are strong localization, Sinhala/Tamil support, clear pricing, quick API onboarding, and a white-label reseller option. The drawbacks are limited disclosure around international coverage, payment methods, and compliance details, while WhatsApp and HLR have not yet been officially launched. Richmo is better suited to local Sri Lankan businesses, marketing teams, OTP services, campaign messaging, and SMS resellers. If you need a compliance-oriented communications platform for multiple countries, you should conduct additional due diligence on coverage, compliance credentials, and SLA terms.
The website does not provide information on availability from mainland China networks, RMB payment, or local filing/registration, so its China access status is unknown. For China-based teams that only need domestic SMS, Alibaba Cloud SMS and Tencent Cloud SMS should be compared first. For international SMS, alternatives such as Twilio, Infobip, MessageBird, and Vonage are worth evaluating.
