Free sandbox email API. Credits that roll over.

Most email APIs make you verify a domain before you can really test. Your first “test” is already a send. Transmit starts in a free sandbox: separate keys, simulated email, real webhooks. Sandbox keys never send — like Stripe. No domain to start. When you’re ready: subscribe, verify domain, create a live key. Same API. Real delivery. $20/mo adds 30,000 emails. Unused credits roll over. No tiers. No midnight reset. Build first. Send when you’re ready. transmit.dev
Sandbox keys never send. Live keys never pretend.
Free sandbox (no domain to start) → monthly retainer → real inboxes. $20 / 30k / unused balance rolls over while you’re subscribed.
Happy to answer anything on the sandbox, keys, or the rollover math.
