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.
“We run our own SMTP servers and manage our own IP reputation. No shared black boxes.”
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 email services tell you an email was “delivered” and call it a day. We show you exactly where it landed, why, and how to fix what's broken.
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.
One API endpoint, standard HTTP and JSON. No SDKs to install, no config files to wrangle. You can be sending emails before your coffee gets cold.
Separate your email types. Set up alerts. Protect your sender reputation. You decide how your email infrastructure works, not us.
Plain HTTP and JSON. No SDK required, but we have them if you want them.
