Frequently asked questions
No. It is an overview. Each “alternative” guide goes deeper on one tool with official sources.
No. Yes means the criterion is clearly covered per sources. The right tool depends on your need (mail client, AI drafts, explainable triage, etc.).
Siftbox and SaneBox cover generic IMAP. Spark too, but via its app (partial). Fyxer is limited to Gmail and Outlook: ruled out for IMAP-only mailboxes.
