(I hope this question counts as being tangentially related to outlining insofar as it's a question of the structured, visual display of information.)

I tried out the new Hey.com email service, and the one feature that strikes me as uniquely efficient is the "Focus & Reply" view, which shows a vertical ribbon of emails (with body text) that need replies, and each email has a reply box to its right. This allows for a highly streamlined way of replying to a bunch of emails quickly. Does anyone know of any email programs that include a similar feature/view?

Which platform? I wouldn't pay subs for an email client. Best one for windows Mac Linux is free & open source too. Thunderbird from Mozilla.

If paying for secure email app, proton by the same few scientists from CERN who setup the proton VPN. Tgough even that has free version apps on the app stores.

On Android the best client is aqua which even on the phone gives me dual panes, pane divider can be moved too. List of multi emails: Gmail, MS outlook Hotmail, Yahoo, etc or even ones' own domains' pop3 servers appear in the left Pane. With a few top folders for each + Other folders for that email visible in left lane. Right pane shows emails list for the folder chosen + from the email account chosen in the left Pane. Clicking on email, can see quick reply icon at bottom. Free version:

By the mobisys team (have their licensed dictionaries' apps too: Oxford Collins etc) & one of the biggest selling apps globally, regularly updated. Nice with dual panes, multi email accounts in left pane, dark themes, on Chromebooks or even phones. Works well.

Don't know if above apps fit OP's request, typed as might help others. Good luck.

Thanks, @washere. To answer your question, for the moment, I'm ideally looking for something either online or for Windows, but if there is something on another platform that includes the feature in question, I would be interested to know.

By far the best on windows, and Mac Linux too, is Thunderbird. Totally secure, free, open source, will never die as legions of coders willing to step in, plus Mozilla Corp backing.

Can have multi emails on it, Gmail MS outlook Hotmail, Yahoo etc own domains pop3... All appear in left pane like aqua but on big desktop. Regular updates.

Plus hundreds of plugins, themes, calendars, todos, etc which let you shape it into whatever you like. The only option for long term investment of time for many. I use dark theme, and their Beta with even more updates. Nothing comes close. Just ask on their forums for exactly what you want and someone will point the right settings & plugins.

+ per OP: if you right_mouse click on an email title in the list of emails in mz thunderbird, option: Reply to sender only, is available, plus a few other reply.... & forward options.

To return to your original question, Lucas: I guess the closest thing to Hey is Readdle’s Spark (available only for macOS and iOS, unfortunately). You’ll find a description here: https://sparkmailapp.com/features

While it hasn’t got Hey’s “Focus and Reply” view, exactly, it does have a smart inbox, smart notifications, deferred replies, follow-up reminders and other rather nice features.

Unfortunately, although I’ve tried to use it multiple times, I’ve never been able to get it running satisfactorily on my various MacBooks. But others are full of praise!

Cheers,
Bill

Oops, sorry, I’ve just realised it’s available on Android, too!

Another interesting option for Mac users is Canary Mail, which is also a single app (like Spark) – i.e. not an e-mail account aggregator (like Hey and others). Canary specialises in security, but has a number of other nice features, including a separate “Files” view that allows you to scope all the files you’ve been sent recently (just like Hey, in fact).

I currently use Airmail as my main mail app (having been increasingly irritated by Apple Mail), but my recent tests of Canary suggest it’s just as good, and also very nimble. However, it’s still early days. Like Airmail, Canary Mail is a one-off purchase.

Canary also has a deferred-reply (“snooze”) feature. What I particularly like about it is its very streamlined interface – nothing extraneous on there (unlike e.g. Airmail, which is a bit over-optioned to my mind). Canary is extremely easy to use. I don’t like the very latest version of Airmail (at all! I’m still using V4.0 in V3.0-compatibility mode), so I’m hoping Canary Mail will prove irresistible!

It’s fully cross-Apple (macOS, iOS, iPadOS), and they’re just about to release an Android version.

And yes, I think e-mail clients could very reasonably be regarded as “outliners”. Folding, threading, two/three-pane outlines, filters, search functions, in some cases even tagging – they match the definition. Indeed, Outlook tends to be used as a kind of omni-inbox by corporate clients (or at least, it was in the old days – but it’s been years since I used Outlook). Same applied to the now defunct Lotus Notes (great concept, flawed execution).

Cheers!
