Start on the free plan without a credit card. Yearly billing saves 15% on Starter and Pro, 20% on Scale. Transparent overage: $0.60, $0.50, or $0.40 per thousand emails by plan, billed only for what you send. Zero per-seat charges, ever.
Moving from Resend, Postmark or SendGrid? We will do it for you.
Templates, sending domains, suppression lists and webhook endpoints, moved across and verified against your live traffic before you cut over. Included on every paid plan, at no cost.
Limited to the first 50 customers, because we are a small team and we would rather say so than quietly stop replying.

Honest comparison
Where we excel, and where others focus
Every row in our column is a capability you can check against the API today, not a roadmap. If you need a drag-and-drop newsletter builder for marketing campaigns, traditional visual campaign tools are designed for that. But if you need bulletproof transactional infrastructure, hardware-grade AI agent allowlists, and a hosted MCP server with an architectural ceiling, choose SadaSend.

Questions people actually ask
- Is the free plan really free, or is it a trial?
- It is free and it does not expire. You get 6,000 emails a month, every month, and the counter resets on the same day each month — a side project can sit on it indefinitely. Every guardrail and all ten MCP tools are included; nothing is held back for paid plans. The one limit that is not monthly is the shared onboarding domain, which allows 100 messages per account for the life of the account so that one signup cannot spend a sending reputation everybody shares. Verifying your own domain lifts it.
- Why is the free plan a monthly allowance with a daily cap?
- Because a shared sending reputation is the one asset an email provider cannot buy back once it is spent. 6,000 emails a month is enough to run real side projects and early-stage production workloads, while the 200-a-day burst limit and warmup ramp ensure new senders build flawless deliverability rather than burning their domain.
- What happens when I hit my limit?
- On a paid plan, sending continues and the overage rate applies — $0.60, $0.50 or $0.40 per thousand depending on the plan. On the free plan there is no overage: sending hard-stops at 6,000 emails, nothing is charged, and your logs and domains stay intact.
- Do the agent guardrails cost extra?
- No, and they never will. Scoped keys, per-key rate limits, recipient allowlists, approval mode, dry run and the full MCP server are on every plan including the free one. Selling the ceiling only to people who can already afford it would mean nobody ever finds out why it matters.
- Can I pay yearly?
- Yes. Starter and Pro are 15% cheaper paid yearly, and Scale is 20% cheaper. Resend, Postmark and Mailgun do not offer annual billing at all.
- Will you help me move from another provider?
- Yes, at no cost on any paid plan. We move templates, sending domains, suppression lists and webhook endpoints, and verify them against your live traffic before you cut over. It is limited to the first 50 customers because we are a small team and would rather cap it than quietly stop replying.
