How do you organize aliases in Proton Mail? (+aliases vs Additional Addresses vs Hide-my-email for different categories)

Hi everyone,

I recently switched to Proton Mail Plus and imported everything from Outlook and Gmail. I want to set up a good system with organization + decent privacy, but I’m a bit overwhelmed by the options.

I have these main categories I want to handle:

• Bank (finance/investments)
• Official / Public (government-related)
• Subscriptions (Spotify, PSN, YouTube Premium, etc.)
• Development (GitHub + Hostinger)
• Social media (notifications)
• Primary address for real people (family/friends) + official mail

I’m trying to decide between:

• +aliases
• Additional Addresses
• Hide-my-email aliases

My questions:

1. How do you typically split your aliases across categories like finance, subscriptions, development, official/government, and social?
2. Do you use Additional Addresses for important things (bank, official) and +aliases for everything else?
3. Do you use Hide-my-email for specific categories, or mostly for random/one-off signups?
4. Any rules of thumb you follow (e.g. “never use +aliases for finance” or similar)?
5. Do you just use a custom domain and create additional Addresses

I want a system that’s not too complicated, but still gives me good organization and some privacy protection in case of data leaks.

I have read the article from Proton Proton Addresses and aliases

Would love to hear how others have set it up in practice.
