Your AI Agent sends the messages.
Email and SMS infrastructure, run by your agent. Describe a workflow, approve it once, and it builds the automation and sends on its own — every step logged, every channel on one bill.
Agent workflows
The jobs that used to take a sprint.
Start with an event or just ask. Approve once — it runs on every channel.
Win back customers who've gone quiet — email them, then text whoever doesn't open.
Email now, text the unopened tomorrow.
Segment · 12,408 contacts
only if the email went unopened
Live. Email now, the text tomorrow for whoever didn't open.
Channels
Email, SMS, and automations.
One wallet, one audience, one set of primitives — more channels soon.

- Push
- Slack
- Live chat

Transactional and marketing, one domain.
Receipts and resets next to campaigns — same contacts, same suppression, one bill.
Transactional
Receipts, resets, alerts. Idempotent, tracked per message.
Marketing
Campaigns priced per send. The unsubscribe footer is automatic.
Templates
Design visually or in code — the same document either way.
SMS
Your agent sends the text.
Two-way SMS on the same contacts and the same balance as email.
176 countries
Toll-free, 10DLC, and Sender IDs, registered in our wizard.
Consent enforced
STOP, quiet hours, and per-handle consent are checked at send.
One balance
A text spends the same sending balance as an email.
Platform
Everything in the box.
The channels, the platform around them, and the agents that drive it.

Infrastructure
One system underneath.
Delivery, consent, retries, and logs are handled below the API — the same way for email and SMS.
DKIM keys rotate without downtime, domain records are re-checked every minute, and bounces and complaints suppress the address before you can send to it again.
Unsubscribe, STOP, quiet hours, and per-channel consent are checked at send time by the platform, not by your code.
Webhooks are signed and retried seven times over nineteen hours. Every automation run keeps a step-by-step log you can pause or replay.
