API
One call
From, to, subject, HTML or text. Node, Python, REST or SMTP. Same payload either way.
Email API for your product.
Send transactional mail with one call — from, to, subject, HTML or text. Then watch it land: delivered, opened, clicked, bounced.

From your domain
Verify DKIM, SPF and DMARC first. Then the message looks like you, not a stranger.
Log
Then watch it
Delivered, opened, clicked, bounced — tied to that send, not a monthly export.
A timeline per email
Not a monthly CSV. Each send has its own log, so you can answer “did it arrive?” without guessing.

Attachments and headers
PDFs, invoices, reply-to, custom headers. The same call that sends a password reset can send a receipt with a file.
REST, Node, Python, or SMTP — pick the door that fits the app.
