01Problem

The challenge

A company wanted to run email marketing on Sendy, a self-hosted newsletter application, rather than pay per-subscriber fees to a hosted platform. That meant configuring Amazon SES for outbound delivery, wiring Sendy to send through it, keeping subscriber lists in sync between the two systems, and setting up monitoring so a delivery or bounce problem would surface before it hurt sender reputation. The company also needed documentation covering install, configuration, and maintenance, so the setup wasn't a black box.
