Team plan includes 10k emails + 1k SMS. Past that, each email is $0.40/k and each SMS is $0.0075. Billed monthly via Stripe; you can set a hard cap in the dashboard to bounce sends past a budget.
Every org gets sok_test_* API keys. Test sends never hit the provider, never count against quota, and never charge you. Run your CI against them.
Yes. Our API is intentionally close to those shapes; most callers swap by changing one base URL + the auth header. Enterprise plan includes migration help with templates + audience import.
Yes, on Enterprise. Register your entity + DLT-approved templates from /overview/dlt, then send to +91 numbers by passing dlt_template_id on the send. Carrier-side India rejects anything not matching a registered template.
AWS SES allocates IPs scoped to your org. Your domain assignments route through those IPs instead of the shared platform pool — improves deliverability isolation and protects against neighbor spam. Pools take 24–48h to provision and 2–4 weeks to fully warm up.
Account stays read-only for 30 days. Use the export endpoint or the dashboard's Settings → Export to download everything. After 30 days, all data is hard-deleted from primary storage; audit log archives (if enabled) keep regulator-required entries for the contracted retention period.
Free forever plan. No credit card. No “sales call” ambush. Just an API key.
