Amazon SES vs Buck2

Amazon Simple Email Service (SES) is a cloud-based email sending and receiving service from AWS designed for marketers and application developers. It supports transactional, marketing, and bulk email delivery with deliverability tools, reputation monitoring, and email authentication.

Buck2 is Meta's open-source build system, a complete rewrite of the original Buck. It provides fast, reliable, multi-language builds with remote execution support and a Starlark-based configuration language.
