Send emails using OCI Email Delivery’s HTTP interface

Oracle Cloud Infrastructure (OCI) Email Delivery is an email sending service that provides a fast and reliable managed solution for sending both high volume bulk and transactional emails. Previously, email delivery contained only a simple mail transfer protocol (SMTP) interface. However, we recently announced a new HTTPS REST API for email submission, improving performance, eliminating configuration complexity, and increasing rates of successful inbox placement.

SMTP versus HTTPS for sending email

SMTP submissions require SMTP credentials, while HTTPS submissions support any standard OCI software developer kit (SDK) authentication methods. We recommend HTTPS over SMTP for your development as the restful endpoint streamlines your development and provides more authentication options.

Getting started

A while back I created a step-by-step guide for sending email with email delivery’s SMTP interface. I recommend reading that first to understand email delivery and its features. With this new release, it only feels right to do a simplified tutorial using this new feature. For the detailed instructions, see Sending Emails using the Oracle Cloud Infrastructure Email Delivery Service HTTP Interface. Experience this new capability today!
