About us

Launched in 1995, we were the UK's first SMS Gateway, and 29 years on, Kapow is still leading the way. We are committed to providing cost effective, reliable, high speed messaging services, and aim to meet the demands of small and large clients alike.

Our SMS Gateway enables the sending and receipt of text messages between the Internet and mobile phones; using web browsers, email or our simple HTTP interface/API. We like to understand your requirements, and to assist in realising your goals. For this reason each client receives the personal attention of a dedicated Account Manager.

So that you can have complete peace of mind, the Kapow network and services are hosted in ultra secure data facilities; with high-speed Internet connectivity, back-up power supplies, load balanced/clustered servers, system monitoring and 24hour technical staff.

There are no long-term contracts, monthly fees or set-up costs. You simply pay for your messages!

Kapow is operated by Cygnet Internet Services Ltd and represents the strongest corporate SMS messaging solution on the market today, offering an average UK delivery time of under 4 seconds!
