Add Transactional Email Sending

About this workflow

Integrate real transactional email capability into the existing app using SendGrid (or similar) with persistent templates and an API endpoint.

What happens when you run it

1. 1
   Provide the app with real SendGrid (or chosen provider) credentials and install the SDK.

Best for

• •Recurring tasks you currently copy-paste between tools.
• •When a single prompt isn't enough — you need a chain where output(n) feeds prompt(n+1).
• •Fork and adapt if your inputs differ materially from the author's use case.
