What each says it does

defluff

In its own words, on Claude Code: claude-plugins-community:

Reverse the AI in corporate email. For every message Defluff guesses what prompt the sender gave an LLM, classifies urgency (ACTIONABLE / RESPONSE-NEEDED / FYI / NOISE), and extracts 3–5 bullets of real intent. Handles single emails, threads, and batch triage. Detects invoice fraud / BEC, phishing, fake recruiters, fake interviews, conference scams, and crypto pitches with specifically named red flags — lookalike domains, fake forwarded approvals, urgency + payment redirects.

mailprobe

In its own words, on Community GitHub marketplaces:

Verify email addresses in real time from your assistant: deliverability, disposable and role addresses, typo fixes. Nothing is sent to the address. Hosted in the EU (France).
