AWS Project: Architect and Build a Serverless Email Marketing Application | Step by Step Tutorial

AWS Project: Architect and Build a Serverless Email Marketing Application | Step by Step Tutorial

The best way to learn AWS is to actually BUILD something with it! Build something that uses several AWS services, and get all the pieces to work together. In this hands-on tutorial, I’ll walk you through how to design and build a simple serverless email marketing application from scratch. When we’re done, our system will send emails on a schedule, grabbing HTML email templates and a list of contacts from an S3 bucket.

We’ll be working with five different services: Simple Email Service (SES), EventBridge, S3, Lambda, and Identity & Access Management (IAM). As we go, we’ll talk about high-level requirements for each, and then walk through how to set them up.

?***What you need to follow along***?
• Email addresses (to send to) that you can validate (can be personal email addresses)
• An email address (to send from) that you can validate (needs to be from your own domain)
• Basic knowledge of AWS
• A text editor/somewhere to write HTML code (or use mine)
