The guides worth reading first
The list above is ordered by date. These are ordered by usefulness, and they are where most people should begin regardless of when they were published.
- How to create a secure email account
The whole setup in dependency order, provider-agnostic. Start here if you have not chosen anything yet.
- Email security threat model
Who can realistically read your mail, and which of those threats switching provider actually fixes.
- ProtonMail vs Tuta
The two-provider decision most readers are actually making, on encryption coverage and legal record.
- Encrypted email provider matcher
Answer a few questions and get a shortlist. Hard requirements eliminate providers rather than down-rank them.
- ProtonMail setup guide
Account creation, the day-one privacy settings, custom domains, and a migration that does not lose mail.
- Proton Mail settings reference
Sentinel, address verification, the Bridge IMAP and SMTP values, and the DMARC policy that stops forgery.
- Email aliases for privacy
One address per service, so a leak is traceable and spam stops when you delete the alias.
- SPF, DKIM, and DMARC setup
The three DNS records that get your mail delivered and stop anyone spoofing your domain.
