Email is the master key to your digital identity. Every website, service, and app asks for email. Giving your real email exposes you to spam, tracking, and data brokers. Email alias services solve this by generating unlimited temporary addresses that forward to your real inbox. This guide compares the best privacy-focused options: SimpleLogin, AnonAddy, Firefox Relay, and Apple Hide My Email.
Why Email Aliases Matter
Without aliases, your email becomes:
- Spam target: You give email to 50 websites; 40 sell your address to spammers
- Tracking vector: Newsletters use your email to cross-reference behavior
- Password reset attack: Hackers know your email → reset password → lockout
- Data breach exposure: Single leaked address; need to change password on 100 sites
With aliases:
- Each website gets a unique, disposable address
- Spam goes to alias, not your real inbox
- Breach of service X doesn’t expose your main email
- You can kill an alias and stop any service at will

Advanced Strategies
Strategy 1: One Alias Per Category
Instead of one alias everywhere, use categories:
Banking aliases: bank_safe_jdks@simplelogin.io
Shopping aliases: shop_nike_kdjs@simplelogin.io
Social aliases: social_reddit_jdks@simplelogin.io
Newsletter aliases: news_techcrunch_jdks@simplelogin.io
Benefit: If one service gets breached, you know exactly which one.
Strategy 2: Catch-All Domain (SimpleLogin Pro)
With your own domain (e.g., yourdomain.com):
Set up SimpleLogin catch-all:
- anything@yourdomain.com → forwarded to your real email
- Can reply as anything@yourdomain.com
- Create infinite aliases without pre-creating them
Usage:
1. Website asks for email
2. Type: "amazon_2026@yourdomain.com"
3. SimpleLogin automatically catches + forwards
4. No need to pre-generate alias
Cost: Domain ($10–$20/year) + SimpleLogin Pro ($30/year) = $40–$50/year
Strategy 3: Integration with Password Managers
1Password:
Settings → Vaults → SimpleLogin Integration
- When creating new password, can auto-generate SimpleLogin alias
- Saves alias + password together
Bitwarden:
Tools → Generator → SimpleLogin
- API key: Get from SimpleLogin settings
- Auto-generate alias when creating password entry
LastPass:
Settings → Connected Apps → SimpleLogin
- Similar integration; limited compared to 1Password

FAQ
Q: Can data brokers track me using aliases? A: Harder, but not impossible. If an alias gets sold to a broker, they can’t directly link it to your real email. But if you use same alias on multiple sites, cross-referencing is possible.
Q: What if I forget my alias for a service? A: Most alias services have dashboard history. SimpleLogin, AnonAddy show all generated aliases + which sites use them.
Q: Can I reply from aliases? A: Yes (SimpleLogin, AnonAddy Pro, Firefox Relay Premium). Service sees alias, not your real email.
Q: What happens if I delete an alias? A: Future emails to that alias bounce. Services can’t contact you. Use carefully for sites you want to keep.
Q: Are alias services trustworthy? A: Check: Open source? Audited for privacy? Location? SimpleLogin + AnonAddy are strong. Firefox Relay backed by Mozilla. Apple is closed-source but secure.
Q: Can my email provider (Gmail, Outlook) see which aliases I use? A: No. Alias services are intermediaries. Your email provider sees forwarded emails from alias servers, not the alias details.
Q: What if a website blocks alias emails? A: Some sites (banks, Apple, Google) reject non-major email providers. Use real email for critical accounts; aliases for everything else.
