Block Beacon Attacks. These are invisible pixel-sized images or links used for marketing that are automatically opened when email is downloaded. In other words, before you open the email. These get your geolocation using a reverse IP lookup.
Solutions: Use a VPN or your carriers data network or a privacy oriented email client like Thunderbird on the desktop and K-9 Mail for Android. Also set your clients not to auto-download remote images.
Resist BigTech Relationship Mapping
Solutions: Use a Gmail address for all Google related maintenance & app logins and for nonsense sites but don’t include your real name, phone# or physical address in it and make sure its an email address that isn’t in your contact lists. Or use a paid email provider and don’t give that address to anyone including your real contacts.
Don’t Feed BigTech Profilers
Email left on the server is scanned for keywords.
Solutions: Use POP3 to auto-delete server-side email when you download them not IMAP. Set up an auto-purge on the ISP’s inbox and trash.
Prevent IP Leak on Send
Email headers contain your IP address. These are used for geolocation via reverse IP lookup.
Solution: use a VPN or your mobile carrier’s data network or StarLink.

There are sites that search the net to find all the places where your email has been used.
Make it harder for data brokers and advertisers to link accounts and track activity.
Some sites make it difficult or impossible to unsubscribe so just disable the alias instead.
