About Secure Mail Guide
Secure Mail Guide covers encrypted email in practice: how email encryption actually works, creating and hardening a secure email account, comparing Proton Mail, Tuta and Mailfence, configuring Proton Mail settings including Bridge and custom-domain DMARC, PGP with GPG, Thunderbird and Gmail, S/MIME and Purview in Outlook, aliasing, SPF and DKIM authentication, building a realistic inbox threat model, migrating away from Gmail without breaking your mail flow, and choosing a provider for a small team.
Comparisons are drawn from provider documentation, published audits and the underlying standards, and every article names the sources it was written from so you can check the original rather than take this site's summary of it.

19 articles are published so far. New articles are announced on the RSS feed; there is no fixed publishing schedule and this site does not promise one.
How these articles are produced
Articles are researched from primary sources: vendor and project documentation, published standards and specifications, release notes, advisories, and measurements published by the people who took them. Drafts are produced with AI assistance and then edited against those same sources before anything is published. Where a figure comes from a datasheet or a third-party measurement, the article names the source and links to it so you can check the original rather than take this site's summary of it.
Everything here is published under the Secure Mail Guide Editorial byline. That is an editorial desk, not a person, and no article on this site claims hands-on lab testing, benchmarking, or first-hand measurement. Nothing here should be read as a report of something this site physically tested.
Corrections
Getting it right matters more than getting it first. If something on this site is wrong, out of date, or missing the source it should cite, email hello@securemailguide.com with the page and the specific claim. Substantive corrections are made on the page itself rather than quietly dropped.
How this site is funded
This site carries no affiliate links, no referral links, no sponsored content, no paid placement and no display advertising. No provider named anywhere on this site pays it anything, and none has been given sight of an article before publication. Rankings and comparisons are set by the published evidence, because there is no commercial relationship here that could pull against it.
The full position is on the disclosure page. Read it before acting on anything here that reads like a buying recommendation.
