Microsoft 365 is providing the function

As me many users need this option. Can you please implement that before the end of the year ?

Well, it's been almost 10 years and we have yet to see this basic (but really important) feature implemented 😕

While it's technically possible to do right now using Sieve filters feature [ https://proton.me/support/sieve-advanced-custom-filters#managing-expiration ], not everyone is willing/able to learn the Sieve programming language just for this. So it should be added in the user-friendly manner to the "Add filter" UI or in the Folder settings

Auto deletion by folder is very important to me.

I have many years experience with messaging...let me not date myself...cc mail...lol But seriously, we need a way to set expiration aka deletion of emails on custom folders.

I would love specific e-mails to be automatically deleted after x days based on a specific folder, filter or label.

I would like Proton to provide system tags/labels that dictate retention such as 30 days, 60 days, 90 days, 180 days, 365 days. These tags could then be used in rules to assign the tag to all incoming emails. Proton would delete any emails older than the stated tag.

If I haven't looked at an email 180 days, chances are I never will, just delete it.

I would love the ability to delete mail in a folder after x days. This is the main reason I have not switched fully to protonmail.

For newsletters this feature has been around for many years on my old @live.nl account from MS. have been looking for it ever since.
Would be nice if this 2015 idea would get implemented.

This would be a helpful feature. But from a UX perspective, I would make it configurable on a per address basis.

I would suggest this flow:

1. Allow users to set the max. lifetime of messages in the Trash folder (from 0, disable trash functionality completely to 30 days)
2. Allow users to set the max. lifetime of email messages, i.e. the "auto delete" functionality
3. Show a new tab "Expiring Soon" on the left side, just like for scheduled messages, when the functionality is activated.
4. Move email messages to Trash.

This allows fine-grained control over both expiring messages and a "grace period" for messages that have been moved into Trash.

This would be helpful

I wouldn't say for the folder but for filter, the auto delete after x hours feature can help a lot in deleting OTP or verification code email

Along these lines, how about an action in the sieve mail rules, that allow you not only to move or categorize, but also let set the maximum days to keep this mail in this rule?

I feel like this should be a basic feature at this point.

Yes please, why is this not implemented yet, like a "Rule" implemented in Outlook, for example. In fact, let's just have a comprehensive set of options to make into rules, similar to the way the "Filters" work so well at dealing with emails as they arrive.

Agreed that this is a needed feature. I would like to auto-delete my "Newsletters" folder after a month to clear it out. A bit concerning that this feature was first requested almost a decade ago and we still don't have it.

Aligns with this idea: https://protonmail.uservoice.com/forums/945460-general-ideas/suggestions/46541965-self-destruct-action-on-filters

https://protonmail.uservoice.com/forums/284483-proton-mail/suggestions/15831865-custom-expiration-after-date-trigger-for-receive

By folder or tag would suffice. Want options to auto-delete by calendar options (last day of the month; or, first day of the month, every Sunday at midnight, etc.)

Agreed, this is an absolutely critical feature. And I would also like to choose whether to include/exclude emails by tags, folders, contacts, starred etc to make sure only unimportant emails are deleted.

Would love to see this ability for folders, filters, etc. Use this with ZohoMail to get rid of frequent promotional emails. And yes, the ability also to choose the number of days after which to delete.

We need this asap.
