Email privacy is not a binary. Your inbox leaks information in several distinct ways, and each leak has a different fix. Plugging all of them at once is rarely necessary; knowing which ones matter for your situation is the useful skill.
1. Block remote images by default
Every HTML email can contain a tracking pixel — a 1×1 transparent image whose URL is unique to you. When your mail client loads it, the sender logs your IP address, device type, and the exact time you opened the message. The fix is simple: disable automatic remote image loading in your mail client settings. Load images manually only when you trust the sender.
If you use EmailGenerator.pro, this is already handled — all remote images are blocked before messages are stored, regardless of your client settings.
2. Use aliases for ongoing signups
Your primary address is your identity. Every site that holds it is a potential breach vector. An alias (from your mail provider, or a dedicated service like SimpleLogin or AnonAddy) gives senders a different address that forwards to your real inbox. You can disable an alias the moment it starts generating spam, without changing your primary address.
For one-off signups where you do not need future access, a temporary inbox is even cleaner — it does not forward anywhere, and it leaves no address to manage.
3. Choose a mail provider that does not mine your content
Some free email services scan message content for ad targeting. Alternatives like Proton Mail, Fastmail and Tutanota do not. This is not a question of encryption between servers — it is about what happens to the message once it is stored. If your use case is sensitive, the storage model of your provider matters more than any individual action you take.
4. Be aware of what email headers reveal
Every message you send carries an email header that records, among other things, the IP address of the sending mail server. If you send from a mail client on your home network, your home IP may appear in the header. Most webmail providers strip or mask this, but a desktop client on a direct connection does not.
5. Use a temporary inbox for any new relationship
Before you hand over your real address to a new service, ask whether you actually need the account to persist. Download gates, one-time verification steps, trial signups, and forum registrations where you will never post again are all cases where a temporary inbox is the cleaner choice. The address expires, the marketing list never gets a real target, and there is nothing to manage.
The one common mistake
Treating email privacy as all-or-nothing. You do not need to replace every address simultaneously. Start with remote image blocking — it is a single setting change and it stops the highest-volume tracking immediately. Add aliases as you encounter new signups. Use temporary email for disposable interactions. Each step independently reduces your exposure.
