What is Bulk SMS?

Bulk SMS refers to sending a large number of SMS messages at once to a group of recipients, typically using an online platform. It's commonly used for marketing campaigns, transactional alerts (like OTPs and order updates), event notifications, and customer engagement. In Kenya, bulk SMS is especially effective due to the high mobile phone penetration across both urban and rural areas.

How Bulk SMS Works in Kenya

Bulk SMS platforms in Kenya allow you to upload or manage contact lists, compose your message, schedule or send instantly, and track delivery reports in real time. Most platforms use short codes (e.g., 22022) or alphanumeric sender IDs (e.g., STATUM). Delivery success depends on whether you’re sending promotional or transactional SMS.

Types of Bulk SMS

Promotional SMS – For advertising or marketing. May be restricted during certain hours and won't reach DND (Do Not Disturb) numbers.

Transactional SMS – For OTPs, account alerts, and system updates. Delivered 24/7 and usually requires pre-approved templates.

OTP/2FA SMS – High-priority messages for authentication, sent through fast, high-delivery-rate gateways.

SMS API – Integrate SMS into your apps or systems. Ideal for developers and automated workflows.
