Email Privacy That Works
Every Connect for Fastmail user gets a full privacy toolkit — no account, no subscription, no credit card. Just install the extension.
Add to Chrome — FreeTracking Pixel Blocker
Marketing emails from companies like Mailchimp, HubSpot, and SendGrid embed invisible 1x1 pixel images that report back when you open their email — your IP address, device, location, and the exact time you read it.
Connect for Fastmail detects and blocks these trackers before they load. You'll see a small icon in the email header showing how many trackers were blocked. Click it for details.
- 2,230+ known tracker domains via DuckDuckGo Tracker Radar
- URL pattern detection for tracking redirects and beacons
- Hidden and 1x1 pixel image detection
- Community-powered Smart Image Intelligence learns over time
Safe Link Preview
Email links are often wrapped in tracking redirects — when you click a link to "Shop Now," you're actually going through the sender's tracking server first, which logs your click, IP, and device before forwarding you.
Hover over any link to see where it really goes. Click it and we'll resolve the redirect chain on our server, then send you straight to the real destination — the tracking server never sees you.
- Hover tooltip shows the actual destination URL
- Tracking redirect detection and stripping
- Server-side redirect resolution — your IP stays private
- Shift+click to bypass and open the original link directly
Phishing & Malware Protection
Before opening any link, we check the destination against Cloudflare's security database for known phishing sites, malware distribution, and other threats. If something looks dangerous, you'll see a clear warning before you visit.
- Powered by Cloudflare Security DNS — updated continuously
- Checks happen server-side, results are cached
- Clear warning modal for dangerous links
- Your choice: go back or proceed anyway
PGP/S/MIME Indicator
Fastmail's web client doesn't show whether an email is digitally signed or encrypted. Connect for Fastmail detects PGP and S/MIME signatures and shows a clear visual indicator in the email header.
- Detects inline PGP signed and encrypted messages
- Detects S/MIME signature and encryption attachments
- Green shield = signed, blue lock = encrypted, gold = both
- Format indicator shows PGP or S/MIME
Smart Image Intelligence
Our community-powered system learns which email images are legitimate content and which are trackers. When you reveal a blocked image, your anonymous classification helps improve protection for everyone.
No personal information is ever shared — only normalized URL patterns and sender domains. You can opt out anytime in your Account Portal.
- Four protection levels: Strict, Smart, Balanced, Notify
- Community whitelist gets smarter over time
- Classify images as Content, Ad, or Tracker
- Opt-in by default, opt-out anytime
