How it works

Optimize your development time and resources by connecting to the Send SMS API. Focus on your application and add SMS functionality there. Through the API you are connected to KPN’s Short Message Peer-to-Peer (SMPP) protocol, so there is no need for you to develop and support this protocol yourself. You are also sure your SMS messages are delivered quickly and reliably because of KPN’s SMS engine. KPN has the connections with all carriers so you can send your SMS to any Dutch mobile number.

You can...


Reduce no-show appointments with reminders

You can send a friendly reminder to your customers of their appointments, reducing the number of no-shows dramatically. Use your planning tool to remind your customers in good time by automatically sending an SMS reminder.


Increase conversion with notifications

Products on your website may sometimes run out. You can easily notify your interested customers when the products are available again. Include the URL of the product to simplify the search for them and boost conversion directly.

Alert your employees of incidents and events

You monitor your crucial operating systems continuously. Your employees need to act if unexpected events occur. You can alert your employees proactively by SMS when your systems show irregular performance.
