We built Postject because we were tired of sending emails and hoping they'd arrive.
Now you can see exactly where each email lands, why it got there, and fix what's broken.
msg_01H8K7W9X2VQPF3M6N...curl -X POST https://api.postject.com/v1/send \ -H "Authorization: Bearer pk_live_***" \ -H "Content-Type: application/json" \ -d '{ "from": "hello@yourapp.com", "to": "user@startup.com", "subject": "Welcome", "html": "<h1>You're in.</h1>" }'
Just regular HTTP and JSON.
No proprietary SDKs. No vendor lock-in. Works with whatever you're already using.
Most services tell you an email was "delivered" and call it a day. We show you if it hit the inbox, got filtered to promotions, or landed in spam.
Password resets and receipts use different infrastructure than your newsletters. If your marketing campaign gets flagged, your login emails still work.
We run our own SMTP servers and manage our own IP reputation. We're not reselling someone else's infrastructure or hiding behind a black box.
Every bounce, complaint, and delivery gets tracked. You'll know if an email failed because of a bad address, spam filter, or authentication issue.
Takes about 30 seconds. Your API key is waiting when you land.
Fire off a curl request right away. No configuration needed.
Copy a few DNS records and we'll handle DKIM, SPF, and DMARC.
