Question How Many Email Addresses Should I Really Use for Optimal Privacy and Security?

[lokamoka820]

Hi everyone,

I’m trying to set up a more secure and private email strategy, but I’m unsure how many email addresses I actually need. I’ve heard recommendations ranging from 2 to 10+, with different purposes like:

• Primary/personal communication.
• Sensitive accounts (banking, government, healthcare).
• Online shopping and social media.
• Throwaway/temporary sign-ups.
• Professional/work use.

Some people suggest using alias services (like SimpleLogin or AnonAddy) or a custom domain with catch-all, while others prefer multiple standalone accounts (e.g., ProtonMail for sensitive stuff, Gmail for everyday use).

My questions:

1. How many email addresses do you personally use, and what’s the purpose of each?
2. Do you recommend aliases vs. separate accounts, and why?
3. What’s the minimum setup that still provides strong privacy and security without becoming unmanageable?
4. Any tips on managing recovery emails and avoiding lockout risks?

I’d love to hear your real-world setups and lessons learned. Thanks in advance!

1. Primary/personal communication.
2. Sensitive accounts (banking, government, healthcare).
3. Online shopping and social media.
4. Throwaway/temporary sign-ups.
5. Professional/work use.

That is what I use
1 = my phone Gmail (because it has build-in malware scanner for downloads)
2 = Outlook.com (I like use of Microsoft authenticator)
3= my old ISP (was takenover and as bonus we could keep old email)
4= another Gmail account (in the past you were allowed to open more email accounts)
5- my new ISP for personal professional stuff and for work my university's email

I am using Evolution with 3 unified inboxes, INBOX known senders, INBOX unknown and SPAM works great!

How many email addresses do you personally use, and what’s the purpose of each?
- As much as you can

Do you recommend aliases vs. separate accounts, and why?
Aliases are more protective againt brute-force trials of log in

Any tips on managing recovery emails and avoiding lockout risks?
I use any email as a recovery for other emails, and I do not care much about being locket out; will just create a new account; nothing valuable is linked to email

How many email addresses do you personally use, and what’s the purpose of each?

– 1 personal e-mail addresses (with few different aliases for different things)
– 1 Gmail address for cases when I don't want to give away my personal e-mail address nor aliases
– 2 spam e-mail address (less known local e-mail service and Proton Mail for cases when local e-mail address isn't accepted)

Do you recommend aliases vs. separate accounts, and why?

Depends what you need.

The sign-in alias from my personal e-mail address is never used anywhere to decrease change of getting hacked. Other aliases of the personal e-mail are used for registration on reputable sites, online shopping and personal communication.

For registration on non-reputable sites, I either use Gmail address or those two spam e-mail addresses. Depends on the account importance level.

I prefer not to use those services like Mozilla Relay, because they give random addresses hard to remember.

What’s the minimum setup that still provides strong privacy and security without becoming unmanageable?

Two e-mail addresses with aliases. Similar to what I do.

Any tips on managing recovery emails and avoiding lockout risks?

1. Strong password
2. 2FA (phone number + app + separate e-mail address)
3. Fake answer to security question
4. Sign-in e-mail address shouldn't be used anywhere else and only for sign-in purpose

What is the difference between a 'sign-in alias' and a 'registration alias'? I thought we register on a website specifically to sign in later, or are you referring to something like newsletter subscriptions?

By "sign-in alias" I mean of an alias that is only used for signing into that e-mail account and that isn't registered anywhere else.
By "registration alias" I mean of the alias used for registration to other websites (such as MT).

I have 4 e-mail accounts.
1 PEC (certified e-mail)
1 Tuta Mail account that I manage exclusively on my smartphone

Now, let’s say I want to use email addresses for the following services: banking, government services, charities, online forums, RSS readers, newsletters, social media, LinkedIn, cloud storage (e.g., Mega, Dropbox), online apps (encrypted note-taking, task managers), browser accounts (Mozilla, Vivaldi), and mobile phone accounts (iOS, Android). Which type of email should I use for each?

Tuta Mail: 1 GB of free storage = online banking
For all other requests, you'll have to figure it out yourself.

This is how I have it set up.

Flying.Trampoline.5310@outlook.com -> sign-in alias, only used for getting into inbox (random numbers to make it hard to guess)
John.Doe@outlook.com -> alias used for highly important things (government, banking, etc.)
John.Doe.00@outlook.com -> alias used for important online activity (online accounts, cloud storage, sync accounts and such)
John.Doe.2000@outlook.com -> alias used for online shopping

JDoe2000@gmail.com -> e-mail address for reputable online forums and communities
JDoe2000@protonmail.com -> spam and non-reputable sites

Obviously these aren't my real e-mail addresses, just examples.

That’s an excellent example, thank you. I particularly liked the inclusion of numbers; they establish a clear sense of priority for each account, which is far better than using randomly generated names, as you mentioned earlier.

Glad I could help!

Sort your aliases and online accounts this way, use the security measures I mentioned in my first post and chances of getting hacked are tiniest. Just keep in mind that cookie theft are still a thing, and no account protection measure could save you from these. That's why the most important thing is only to access your online accounts from safe and clean PCs and other devices.

None of my online accounts were ever hacked because of this philosophy. As a member here on forum would say—stay safe, not paranoid! (you know who you are )

Firefox and DuckDuckGo both offer free email mask services:

Firefox’s free email mask service got a massive update

Firefox Relay used to allow you to hide your real email address behind just five disposable ones. Now that number’s jumped dramatically.
