I’ve been on the other side of this as a CTO/CIO — including automotive, where you blitz hard in some months and go quiet in others. What I hated about email APIs: Your first “test” often needs a domain and is already a real send Credits that die at midnight while you’re still paying No clean way to build webhooks/integration before you’re live So I built Transmit : Free sandbox with separate keys that never send (simulated email, real webhooks) No domain required to start When you’re ready: live keys $20/mo → 30k credits, unused rolls over Live today (also on Product Hunt). Roasting welcome — especially on the sandbox DX and whether rollover matters to you. What would make you switch from Resend/Postmark/SendGrid?   submitted by   /u/puchesjr [link]   [comments]
