I would like to suggest an improvement to the filtering system in Proton Mail.

Currently, filters allow conditions based on sender, subject, keywords, etc., but it would be extremely useful to have the ability to create filters based on the age of an email (relative to the current date).

For example, I would like to create rules such as:

Automatically move all unread emails that are older than 10 days (based on today’s date) to a specific folder or highlight them.

Automatically move emails that are older than 10 days and already read to the Trash or to another designated folder.

More generally, the ability to filter emails based on conditions like:

“Older than X days”

“Newer than X days”

Combined with read/unread status.

This type of time-based dynamic filtering would greatly improve inbox organization and automation, especially for users who manage a high volume of emails.
