How to stop sales emails tracking you
A recruiter or sales rep emails you, and opening it can let an outreach tool log the time, device and location. Sales platforms also rewrite links to measure clicks. Mailshade uses declarativeNetRequest to cancel requests to known tracker-pixel domains before they fire. Its local DOM scan detects supported tracking-link patterns and, when you click one, offers the extracted direct destination or the original URL. Choosing direct avoids the recognized redirect. Mailshade works across opted-in Gmail, Outlook, Office 365, Superhuman, Yahoo Mail and ProtonMail, and keeps a local detection history by sender.
What sales tools actually see
Outreach platforms embed tracking pixels and rewrite links. Loading the pixel reports the open; following the redirect reports the click.
Stopping known signals
- Install Mailshade and opt into your mail client.
- Open sales and recruiting email as normal — requests to known tracker-pixel domains are cancelled via DNR.
- For a recognized tracking link, review Mailshade's direct and original choices; choose direct to avoid the recognized redirect.
- Review the dashboard to see which senders produced the most detections.
Why this matters
Open-based scoring can shape when and how often you are contacted. Blocking known pixels removes that known-domain open signal.
You stay reachable
Blocking tracker requests does not block the email itself. Messages still arrive, and the original link remains available when you want it.
FAQ
Do sales emails really track when I open them?
Sales engagement and recruiting tools can embed tracking pixels and rewrite links to log clicks. Mailshade network-blocks known pixel domains and warns on supported redirect patterns, where you choose direct or original.
Will the sender know I blocked their tracking?
No. When a request to a known tracker-pixel domain is cancelled, that tracker receives no open signal and no block notification.
Does blocking stop me receiving the emails?
No. Messages still arrive and display normally. Mailshade blocks requests to known tracker-pixel domains and warns on recognized tracking links; it does not block delivery.
Does this work in Outlook and Superhuman, where sales reps often send?
Yes. Mailshade covers Gmail, Outlook, Office 365, Superhuman, Yahoo Mail and ProtonMail, so outreach lands in any of those clients without its tracking firing.
How much does Mailshade cost?
Core protection remains free after a 14-day Pro trial. Paid Pro starts at $3.99 per month or $19 one-time for Founders Lifetime, capped at the first 1000 seats.
