Transmit
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

Who hunted Transmit?
Transmit was hunted by John Rodkey. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

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.
