Meet your new global SMS platform

We have been delivering SMS for our enterprise customers and partners for 15 years. We asked them what it was about our SMS platform and SMS APIs that made them choose Comapi. Here is what they said:



With a current platform uptime of 100% and a 99.95% SLA, businesses can rely on us to deliver their SMS.


“Speed & Capacity”

Our largest customers send millions of messages to us at once. It’s about being able to ingest huge quantities of messages on our platform, as well as send them out close to real time.


“Global Service”

We currently send to over 156 countries every month. Many customers use our “localiser” service to ensure their messages are sent from local numbers, which also means your customers can reply to you on a local tariff.


“Quality of Service”

We have access to all global networks and are not tied to specific providers. We intelligently route messages to the highest quality networks, to ensure your messages are always received.

How does it work?

“Filtering & Tracking”

Unique filtering technology allows you to automatically filter out numbers that are not live, so you only pay for SMS that are delivered. You can either use the “historical” filter (based on data from your sends) or the “live” filter (which checks first that the number can receive an SMS).

Comapi’s tracking service, shortens URL to make them more character friendly. We then track every click based on a unique ID contained within this URL. Use the service to cut the length of your SMS and get real time proof of engagement. You can even post a live event to your system based on a click-through.

“Localiser & Stitching”

With a vast pool of numbers and local inbound shortcodes we ensure your messages are sent from local numbers. This ensures your customers can receive and reply to SMS at local rates. This means no increased charges from receiving or sending from international numbers.

If your message is sent from a pool number, that number is then ‘stitched’ to the customer and will be used for all future SMS communications - keeping the individual user experience consistent.


An SMS has no value unless your customer actually receives it, i.e. it has not simply been delivered to the network . We report real time on every message, by confirming the message receipt status. Submitting an SMS doesn’t necessarily mean your customer receives it. Comapi’s reporting allows you to differentiate between the two.
