SMS API
Go build something amazing.
More than just a simple SMS gateway.
TextMarks text message API allows you to go beyond just sending a text message to a phone. Create groups, manage and segment your lists, manage opt-ins and opt-outs -- all at a higher layer in the API and platform.
Fast, reliable connection.
Unlike SMS email gateways, which add ugly headers, limit your delivery rate, and can take hours to deliver your messages, our SMS API service gives you a reliable, direct conduit to your users' mobile phones, with a fast connection and a very stable platform.
We do the hard stuff for you.
SMS can be challenging when you have to deal with delivering high message volumes, always-on SMS request handlers, management of opt-ins and opt-outs and compliance issues. TextMarks handles all that for you, so you can focus on building your app.
