It's here: https://nylas.com/pricing
And you can read our blog post about announcing the pricing: https://nylas.com/blog/nylas-pro/
We haven't yet shipped the version which allows you to upgrade, but it's coming shortly.
Thanks, I didn't see an obvious link (should have clicked "more"), wound up on NylasCloud page, which did have pricing, but that linked to a contact form.
Might be worth having a Pricing link/button next to download, and from the Free column, to the download screen.
Also, since the data is all in your cloud, would be nice to have a "web" version, so that I could use the app without needing to install. That would be ideal for me, a web-mail app that I can manage all my accounts from anywhere, even when I'm not on my home computer.
Just a few thoughts.
Thanks for the work you are doing here, I feel that Email is one area that could use a lot of work.
