how to create custom email signature in mailspring

Launching it and polishing the new C++ sync codebase is just step 1. The roadmap and website are still being assembled, but there's some really cool stuff in the works. The goal is to use revenue from subscriptions to pay maintainers (myself, possibly other folks!) to maintain Mailspring indefinitely and/or put bounties on popular feature requests. The pro features still cost money ($8/mo). All of these features have been re-implemented to run locally on your computer. It still has the same great pro features, like snoozing and send later, but doesn't send your email credentials to Mailspring servers. You might not even notice it's an Electron app. It uses roughly half the RAM and CPU of Nylas Mail and idles with almost zero 'CPU Wakes' thanks to new C++11 features, which translates to great battery life. (~40k lines of JavaScript) replaced with a new C++ core based on Mailcore2. It's a fork of Nylas Mail with the entire mailsync codebase

For anyone just catching up, here's the tldr on Mailspring: Hey folks! Mailspring maintainer here - glad to see this on Hacker News.
