How about a AutoDelete feature for specific folders that deletes emails after a user defined amount of time, could be Hours-Days...This could be different for different folders like,sent emails-drafts etc.

love the idea

Set a time for each folder (X days) after which emails in this folder are deleted automatically. Extremely helpful for the "Newsletters"-folder.

I don't think this exists currently... It would be great to have an ability to customise a specific folder to archive or delete emails automatically after a time period. For example, a folder for Newsletters which are interesting enough to not delete immediately, so I pop them in a Newsletters folder, but any email in that specific folder, I can get them to automatically be deleted if they're older than a year old.

I keep most emails around forever, as some obscure emails from eons past still end up being useful in the future somehow. So I don't want this to be a blanket thing on my whole inbox.

And this isn't exactly a real problem I'm having. Currently I can just go in once a month (or so) and delete all emails up to a particular date. But to have an automatic rule set up (for specific folders only) would be really great.

This is a feature I would use on most of my emails.

Most people subscribe to newsletters, and more than they can read within reasonable time. It would be nice it unread newsletters could be automatically deleted after X amount of time. That would keep the inbox clean without to much manual labor.

Yeah I'll put three of my votes on this. I've achieved similar feats for gMail with relative ease using Google Apps Scripts, but I've always wanted it built-in to ProtonMail. It would make the system perfect. Filters and Auto-cleanup scripts working hand-in-hand XD

I'd want one set to auto-archive anything unread after 7 days, and another one set to move mail from the archive to trash as long as it isn't starred after 365 days. This is how I had my gMail set up.

This would be useful as an option within filters. In Gmail, a Delete action is available in filters but if one wants to delay that, one has to use a script. Currently there's no Delete option in ProtonMail filters at all, but if one were to be introduced and with the option to apply a Delay, that would be comparatively simpler.

Do not declutter your Inbox/Sent folder/Archive: Avoid it getting cluttered in the first place! This feature could come in very handy for this.
