DuckDuckGo is here to put a stop to that.
DuckDuckGos new Email Protectionsanitizes emails sent to you, removing the trackers before you receive them.
All of this to minimize whos tracking you online.

DuckDuckGo
Email provider Fastmail caches all images on its own servers, effectively blocking trackers before they get to you.
DuckDuckGo brings the same protection to anyone, no matter what unit or email service you use.
Its essentially a filter your email goes through before you see it, scoured of all privacy-violating tech.

Now, whenever you sign up for something, it’s possible for you to use your Duck address.
Any incoming mail will be routed through DuckDuckGos servers and sanitized.
What about privacy, you ask?
Doesnt this mean DuckDuckGo can read your emails?
Email is sent in clear, plain text.
DuckDuckGo is just another server along the way, and it doesnt save anything apart from your email address.
“DuckDuckGo will never save users' emails for this service.
We don’t need to.
And think about this: Do you trust DuckDuckGo more or less than your current email provider?
If youre using Googles Gmail, for example, you probably trust DuckDuckGo more.
Privacy Essentials
Email is fundamentally insecure.
Its unencrypted, and works more like an open postcard than a letter in a sealed envelope.
But that doesnt mean we have to accept privacy violations.
DuckDuckGos offering is great, because it can be used by anyone.
It doesnt matter, because DuckDuckGos Email Protection works before the mail gets to Google or wherever.
Email may be weak in terms of security, but its strength is its open nature.
Its possible to build all kinds of services on top of it.
Some of these are invasive, but others are pro-user.
The good news istrackers seem to be on their way out.
