You want to protect your email privacy? Good. But which approach is right? Three options are available: Email aliases, disposable email addresses, and email forwarding. Each has its strengths and weaknesses. Time for an honest comparison.
Disposable Email: Fast but Inconvenient
Temporary email services like 10MinuteMail or Guerrilla Mail promise anonymity. You get an address that expires after a few minutes or hours. Perfect for one-time registrations where you don't expect any follow-up.
- No registration needed — instantly ready to use
- Truly anonymous (if the provider is legitimate)
- No permanent access to received emails
- No reply capability
- Many services are blocked by websites
Disposable emails are like burner phones: Practical for one-time use, useless for everything else.
Email Forwarding: Convenient but Complex
Services like SimpleLogin or AnonAddy (now part of Proton) forward emails from an alias address to your real address. You get a separate alias address that forwards everything to your main inbox.
- Emails land directly in your familiar inbox
- You can reply (usually)
- Your real inbox continues to fill up
- If the forwarding service has a data breach, your real address is compromised
Email Alias with Dedicated Inbox: The Middle Ground
FAE and similar services offer a third way: You get an alias with its own mini-inbox. Emails don't land in your main account but in a separate app.
The Security Aspect
The BSI has issued clear recommendations for secure email transport in its technical guidelines TR-03108 and TR-03182. Important protocols like DNSSEC, DANE, and MTA-STS protect the integrity and confidentiality of emails.
Unfortunately, according to a BSI study from February 2025, only 20% of companies have implemented DNSSEC, only 11% use DANE. This means: The majority of email communication is vulnerable.
Practical Test: Three Scenarios
Scenario 1: Newsletter Registration
- Disposable email: Works, but you miss the newsletter
- Forwarding: Newsletter lands in your main inbox
- Alias with inbox: Newsletter in separate inbox, you stay in control
Winner: Alias with inbox — you can read the newsletter without burdening your main inbox.
Scenario 2: Online Shop with Order Confirmation
- Disposable email: You don't get shipping confirmations
- Forwarding: Confirmation in main inbox, but also all follow-up emails
- Alias with inbox: Confirmation in separate inbox, spam easily switchable off
Winner: Alias with inbox — full functionality, full control.
Scenario 3: Support Request Requiring a Response
- Disposable email: No reply possible
- Forwarding: Replying works, but lands back in your main inbox
- Alias with inbox: Anonymous reply possible, conversation stays isolated
Winner: Alias with inbox — anonymous communication without compromises.
The choice is yours. But one choice you should make: Continuing to use the same email address everywhere is no longer an option.
Conclusion
There's no perfect solution for all cases. Disposable emails are ideal for one-time, non-critical registrations. Forwarding works well if you want everything in one inbox.
Dedicated aliases with their own inbox offer the best compromise between control, security, and convenience. They require some adjustment, but the benefits outweigh the costs — especially if you take your digital privacy seriously.
