How to use it well

Claws Mail fits a deliberate inbox workflow with explicit folders and rules. Begin with a small set of filters you can explain, then add templates or plugins only where they remove a recurring piece of manual work.

Configure a mailbox and verify folder mappings before adding automated filtering rules. Create a few rules for predictable messages and check their results regularly. Install plugins only when they solve a concrete need, and review backup options for local mail folders and account settings.
