(unfortunately, I haven't found a way to link directly to the e-mail - if you have any idea how to do it please let me know)
I haven't dug very deep into this yet, but this does seem to be possible. A recent Nylas feature lets you share an email thread from a hosted URL by clicking on the share icon in the toolbar.
When viewing that URL, it has a link back to the original email in Nylas. A sample href is:
href="nylas://?subject=Please%20verify%20your%20email%20address&lastDate=1477261022"
