One compliant sender, however your team wants to text.
Ship the API where you need automation, hand the shared inbox to the team, and let non-technical staff text from email — all on the same number, the same compliance, one bill.
A shared inbox
A no-code shared inbox for the team — assign, note, and reply. Same number, same compliance.
Your email
Send a text by emailing a number; replies come back to the inbox. Zero-code, for non-developers.
The API
REST + webhooks + SDKs. Programmatic sends and alerts, with 10DLC handled by the platform.
The boring guarantees you actually need.
Metered exactly once
Pass an Idempotency-Key and a retried request never double-charges or double-sends. Billing reconciles against the carrier receipt, never an estimate.
Delivery webhooks
Subscribe to status events — queued, sent, delivered, failed — and get the carrier receipt back, so your system always knows what actually happened.
Compliance in the send path
The same gate runs on API sends: consent, opt-outs, quiet hours, and content checks. Non-compliant sends are refused with a structured error, not silently dropped.
Credits never expire
Buy credit, use it whenever. No monthly reset, no annual contract, no expiry on what you've already paid for.

Free to start, no credit card. Grab a key, and we'll have 10DLC handled behind it.
