I'm holding off my downvote to see if i can get a straight answer out of you. Nylas Mail bills itself as the best email app. Them's strong words, but maybe you're worth the claim? Let's see!

I see from screenshots that Nylas has folders and labels. Can i use either of these in the following fashion?

- i can have a tree structure of them

- an email can be in two separate folders/labels at the same time

- folders/labels can be configured to learn which emails to automatically sort into themselves, based on the email contents, by dragging and dropping the email into or out of them

Ball's in your court.

E: Bonus round! In this screenshot there's only 6 emails in the list: https://www.nylas.com/static/img/nylas-mail/hero_graphic_mac... Is there a way to get a list of emails where each line is actually only a line of text tall?

Some quick answers

• If by "tree structure" you mean a folder hierarchy, yep that's supported. I think we have a current bug with dragging nested subfolders but we're working on a fix. (Surprisingly >99% of users have a flat hierarchy.)

• A thread can certainly be in two separate folders (e.g. Inbox and Sent) but an individual message can't be in two folders at once. In that situation there are two copies on the actual mail server. For Gmail/Gsuite this is possible via labels where any thread can have an arbitrary number of labels. We support both systems.

• "labels can be configured to learn which emails to automatically sort into themselves, based on the email contents" -- this is a really cool idea and something we've talked about internally. AFAIK there is no cross-platform mail client that does this today beyond things like manual Gmail filters. It could also be an interesting plugin that anyone could build on NM. We have a Slack chat room where folks discuss stuff like this if you're interested: http://slack-invite.nylas.com/

• And for your bonus round (haha) yes there are 2 different ways to configure the UI. One of them is 3-pane with a reading mode like Outlook, and the other is 2-pane that navigates like Gmail. http://i.imgur.com/Lt0x7O4.png

Also in 3-pane if you make the message list wide enough it will switch into the compact version: http://i.imgur.com/SaGp9eV.png

(Obviously it will show your real mail data. We have a "screenshot mode" for sharing stuff like this without revealing sensitive information.)

That's worth upvotes for the effort alone, thanks. :)

You tend to end up with it only after really long-term usage. All the folders with sub-folders i have got them after they got too big to be just one, e.g. "Perl coding stuff" has several subs, "Shopping", "Clients", "Computer Game Emails", etc. Some clients have additional subs. All started out as a singular one though.

> threads, not singular mails

Ok, fair enough.

> labels auto-learning by drag&drop ... AFAIK there is no cross-platform mail client that does this today beyond things like manual Gmail filters

Opera M2 does it extremely well since ~2000. Google Inbox does it ... eh. Mobile and PC, none, right. The filtering is honestly super easy to implement. It's a bayesian filter. In older email clients those were used to filter out spam. Opera M2 simply gives each folder one (user-configurable) and runs all the filters on each mail that comes in.

And to be fully honest here, i still use Opera 12 as my main browser, along with its mail client and don't see myself jumping ship ... anytime really since for me the combination of mail client and browser is key. However to respect an email client i expect it to be a feature match to Opera M2 at least.

Not interested in Slack. If you had an IRC channel tough i wouldn't need to sacrifice a chicken and a CPU core. :)

Ok, that looks fine. I personally prefer to have the email below the mail list, but that's not a huge thing. Maybe an option to consider. Screenshot mode is cute. :)

You can actually join the chat via IRC/XMPP. No chicken sacrifice required! :P https://get.slack.help/hc/en-us/articles/201727913-Connect-t...

I haven't tried Opera M2-- I'll check it out. Might be a fun hackathon project to train a Bayesian filter on every folder and auto-suggest routing at least.

There was a big IBM Research study a few years ago that showed it's dramatically more efficient to search email versus categorizing messages into folders. Here's a link to the full paper: http://people.ucsc.edu/~swhittak/papers/chi2011_refinding_em...
