MailVault and Pagkugi

Local-first client with a Maildir-style vault of plain .eml files.

At a glance

Open-file storage, offline search, HTML reading, archive-and-delete, Explorer, Insights, custom fields, sender checks, and tracker handling.

Where Pagkugi differs. The closest direct comparison: it shares the open-file storage bet but surrounds it with a much broader conventional feature set and a subscription tier.
