+ Mailspring is a new version of Nylas Mail maintained by one of the original authors. It's + faster, leaner, and shipping today! It replaces the JavaScript sync code in Nylas Mail with + a new C++ sync engine based on Mailcore2. It uses roughly half the RAM and CPU of Nylas Mail + and idles with almost zero "CPU Wakes", which translates to great battery life. It also has + an entirely revamped composer and other great new features. +
++ Mailspring comes packed with powerful features like Unified Inbox, Snooze, Send Later, Mail + Rules, Templates and more. Mailspring Pro, which you can unlock with a monthly subscription, + adds even more features for people who send a ton of email: link tracking, read receipts, + mailbox analytics, contact and company profiles. All of these features run in the client - + Mailspring does not send your email credentials to the cloud. +
