Email to SMS
Send SMS from the email accounts you already use. No new tooling.
Two-way messaging
Replies land back in your systems, not in a shared inbox nobody owns.
Inbound routing
Inbound messages are routed to your endpoint as they arrive.
The control surface
One dashboard for the whole conversation
Send and receive SMS, manage two-way conversations and contacts, and track delivery in real time. No technical expertise required.
Send and receive
Submit over the HTTP API or SMPP. Replies arrive at your endpoint instead of a shared inbox.
Two-way conversations
Track a conversation end to end, including the opt-in and opt-out that keeps it compliant.
Delivery receipts
Every submission returns a receipt, so you reconcile against the truth rather than a summary.
Scheduled delivery
Plan and queue messages for automatic delivery, then follow scheduled sends in real time.
Contacts
Keep the group lists that inbound processing and auto-responders act on.
Reporting and analytics
See what was sent, what was delivered and what came back.
