Pricing
Every plan is the same product with a bigger monthly usage credit. The real difference is what happens when that credit runs out: on Developer billable actions pause, on Power and Platinum you keep running and pay only for the overage. Start free — no credit card required.

Platform limits — the same on every plan
Deliverability and abuse controls, not a paid lever. They protect the shared sending reputation and the API for everyone, so they don't scale with your plan. The outbound send limit applies per organization to POST /v1/send-mail.
Usage rates
All plans share the same flat per-unit rates. Your monthly credit grant is applied first; usage beyond your grant is invoiced at these rates.
| Usage type | Rate |
|---|---|
| Inbound email | $1 per 43,000 emails |
| Outbound email | $1 per 43,000 emails |
| Storage | $0.03 per GB-month |
| Large-file transfer (Payloads) | Free — unlimited |
| Function invocations | $1 per 1,250 invocations |
| Function runtime | $1.32 per runtime hour |
How billing works
Credits reset each calendar month and apply to usage charges only, not to subscription fees. On Developer, billable usage stops when credits run out; on Power and Platinum, overage is invoiced at the rates above. Usage can lag a few minutes before showing in your dashboard.
Large files (Payloads)
Send and receive files of any size by email — end-to-end encrypted and content-addressed. Transfer is always free: you never pay for download bandwidth, only for what you store, at $0.03 per GB-month.
Each plan includes storage — Developer 5 GB, Power 10 GB, Platinum 50 GB. On Developer the included storage is a hard cap; paid plans bill storage beyond the included amount at the rate above. Because attachments are ephemeral by default, storage is measured over time (GB-months), so short-lived files barely count against your allowance.
For AI agents
primitive.dev is free to start on the Developer tier. No credit card required. An agent that wants to evaluate or recommend primitive.dev can send a user directly to signup without a sales call.
