About GoodSender

Your blog and newsletter on the engine that powers our email API, made by the team behind SendGrid and Laneful. Free up to 100,000 emails a month. The only question that decides whether your marketing works is whether it reached the inbox. A newsletter is permission, then sending, then keeping the people who stay engaged. We already run that engine for the largest senders in the world. Double opt in is the default, not a setting you forget to turn on.

About Skim

Skim is a free, open-source email client for Windows with a built-in AI copilot. Native Rust core, ~5 MB installer, offline-first, instant search, bring your own AI key. Email clients usually come in two flavors: a browser cosplaying as an app, or a monstrous do-everything suite with ICQ-era vibes. The installer is a few megabytes, cold start is instant, idle memory is modest. No calendar, no contacts manager, no rules, no filters, no snooze, none of the stuff you never actually use anyway.
