What lights up at each tier.
One plan. Published limits for all six channels.
Most messaging APIs charge per message — a fraction of a cent per email, a few cents per SMS, a conversation rate for WhatsApp. That sounds cheap until you do the maths on a growing product: 50,000 emails a month at $0.001 each is $50 before you've sent a single SMS. Add WhatsApp and the invoice gets unpredictable fast.
Each Senddio plan publishes its email and channel allowances. Email, push, Slack and Telegram stop at the configured limit instead of silently creating an overage. Eligible Starter and Pro workspaces can use metered SMS or WhatsApp beyond the included amount, with usage exposed in rate-limit and billing data.
Predictability is a feature.
Every request is checked against a documented allowance before it is queued. You can see the applicable limits, current usage and reset window rather than discovering an undefined ceiling after a production send fails.
AI credits use the same explicit model: a monthly allocation is attached to the plan, with top-up packs when available. Usage-based charges are limited to the channels and plans that clearly support them.

Pricing & billing — FAQ
Correct. Sign up with an email, verify it, ship code. We ask for a card only when you choose to upgrade to a paid plan.
Pro is meant for production teams running real multi-channel volume with AI features and audit logging — supporting Telnyx, Meta, FCM, Slack and Telegram delivery plus 90-day retention costs real money per account.
Senddio rejects a new request with a clear rate-limit response when its plan allowance is exhausted. Wait for the published reset, upgrade, or use supported metered SMS or WhatsApp overage on an eligible plan.
Yes — Claude MCP + OpenAI tool connectors are included on every plan. Free gives you 20 AI credits/month and full agent-scoped key features. It's designed for indie developers and AI tinkerers to ship real things.
Yes — Enterprise. Reach out via the contact link with your monthly volume, channel mix, and any compliance needs (SOC2, BAA, SSO). We'll come back with a custom quote that includes dedicated IPs.
Any time. We pro-rate the change and you retain your data; only the plan-gated features stop working at the new tier.
Free SMS is capped at 10 messages per month. Senddio covers one managed sender number and U.S. carrier registration fees for Free workspaces, and stops SMS sending at the cap without charging overages. Starter and Pro may use eligible metered SMS or WhatsApp above their included monthly limits.
No. Senddio manages the Telnyx account and covers one sender number and U.S. carrier registration costs for Free workspaces. U.S. businesses still need to provide accurate registration details and wait for carrier approval. Free sending stops at 10 SMS per month, with no SMS overage charge.
