Send from the systems you already use
Your team should not be copying a list out of one system and pasting it into another. Send straight from the software you already run.
A dead integration cannot keep sending
JSON in, JSON out, over HTTPS. API keys you can issue and revoke per system, so a decommissioned integration stops working the day it is switched off rather than the day someone remembers it.
Know what the API will do before you call it
A full, public OpenAPI specification and a live documentation browser, kept up to date as the API changes.
You never have to poll us again
Delivery receipts and inbound replies are posted to your endpoint as they happen. You do not poll us.
Or skip the integration entirely
Email to SMS sends a message by sending an email. It is the fastest way to get an existing system sending, and it needs no development work at all.
Commonly asked
Is there a rate limit?
There is no published per-account send limit. If you are planning a very large or bursty send, tell us in advance and we will size the routing with you so it lands smoothly.
Can we test without spending credits?
Yes. A free trial account comes with 100 messages, which is enough to build and verify an integration.
