Inbox peace is a rare thing. MailWasher Pro gives it back, not by playing whack-a-mole after the spam lands, but by letting you screen messages before your mail app downloads them. You glance at the previews, nuke the junk, allow the legit senders, and only then do you open Outlook or Thunderbird. The latest version keeps that tidy ritual intact, with modern IMAP/POP handling, live learning, and a curated threat feed that helps catch phish before they waste your day.

Key Features
Preview first, download later — check senders, subjects, and small snippets safely on the server; delete/keep at the gate so your actual inbox stays clean. Works with your existing client (Outlook, Thunderbird, etc.).
Trainable junk control — combine your personal allow/deny rules with MailWasher’s learning engine so it gets sharper as you mark spam/ham.
FirstAlert™ cloud intelligence — MailWasher taps a shared spam-signature database (fed by traps and user reports) to block live campaigns and phishing waves faster.
Multiple accounts, POP3/IMAP — point it at one mailbox or many; it plays nice with common providers and keeps your routine intact.
Sane defaults, simple rollbacks — keep a friendly Friends list/Blacklist, preview HTML safely, and undo accidental deletes from the Recycle Bin before you fetch mail with your client.
Low-friction deployment — a standalone offline installer and 30-day full trial make it easy to pin a team-wide full version and keep installer checksums alongside your rollout notes. (Soft LSI phrasing only, not in anchors.)
What’s New
7.15.42 (July 2025) — stability fixes around the installer and HTML rendering; part of a quick sequence of midsummer polish releases.
7.15.37–7.15.38 — crash fix tied to the FirstAlert feed and additional installer corrections. If you skipped a few updates, this line is where things settle again.
7.15.20 (Feb 2025) — Gmail app-password guidance, sync fixes, and better handling for some Microsoft accounts—useful if you manage mixed mailboxes.

Pro Tips
Train a week, then trust. Spend a few days explicitly Delete vs Keep; MailWasher’s learning + your lists will start feeling “automatic.”
Whitelist like a minimalist. Add only the people/services you truly want to sail through. Everything else should face a quick preview.
Use IMAP thoughtfully. With IMAP inboxes holding years of messages, lean on date filters and “new only” checks so you’re screening the current river, not the whole lake.
Gmail/Outlook quirks. If a provider changes auth (e.g., Gmail app passwords, Microsoft tightening), read MailWasher’s update notes and re-auth once; don’t fight stale settings.
Keep a tiny version.txt. Note the MailWasher build (7.15.42), OS build, and installer checksums. If you support others, this makes “it broke” tickets solvable in minutes.
Comparisons with Similar Tools
Mozilla Thunderbird — a full email client with solid built-in junk filters; MailWasher Pro sits in front of your client for server-side screening before anything downloads.
Microsoft Office 2019 — Outlook’s junk mail tools live inside the client; MailWasher helps you delete bad actors upstream, so Outlook receives less in the first place.
AVG Secure Browser — browser-side anti-tracking and phishing protection; pair it with MailWasher to reduce both web-page scams and email-borne phish.

Frequently Asked Questions about MailWasher Pro
1. Does MailWasher replace my email program?
No. It works in front of your client. You preview/delete in MailWasher, then open Outlook/Thunderbird to download only the good mail.

Yes—POP3 and IMAP across multiple providers are supported; you can screen many inboxes in one place.
3. What is FirstAlert—and do I need it?
It’s Firetrust’s spam-signature cloud. It strengthens your own filters with crowd-sourced intelligence; great for fast-moving phishing waves.

Check the release notes, use app passwords/OAuth where required, and re-pair accounts once after major provider changes.
