The new email categories—such as Social, Promotions, and Transactions—are a great way to keep the inbox more organized. However, when a category is muted, it can become easy to forget to check it altogether, even when new messages have arrived.

I would love to see configurable reminders for individual categories. If there are new messages since I last viewed a category, Proton Mail could show a subtle reminder:

• At a chosen time, such as every evening
• At a configurable frequency, for example daily or weekly
• Only when the category contains unread messages since it was last opened

Ideally, this would be optional and discreet—not a push notification for every new email, but rather a periodic summary or reminder.

Previously, filters could be used to silence certain types of email, but those messages would still appear in the inbox and remain visible. Categories solve that problem much better, but muting a category can make it too easy to overlook it entirely. A scheduled reminder would create a better balance between a calm inbox and not missing messages that are still worth reviewing occasionally.
