About this reference
Who maintains this reference, how it is made, and how to correct it.
What this is
emailmarketing.net is a reference on email deliverability: how mail is authenticated, how mailbox providers decide what to accept, and what a sender can do about it. It is free to read, it covers senders on any email platform, and it is written for the person who has a delivery problem in front of them right now.
How it is made
The knowledge base is published from a repository separate from this site's own code, and rendered directly here: there is no hidden content system, so an article is a file, and a correction is a change to that file.
Each article lists the sources it stands on. We are working through those sources so that every technical claim rests on a primary one where it exists — the RFC, the mailbox provider's own documentation, or published M3AAWG practice. Vendor articles may support a point; they should not carry it alone.
The French edition is a translation of the same articles, glossary included — not a shorter version of the reference. Translation is ongoing: an article not yet in French is still there in English.
Who maintains it
Published by the team behind Cakemail.
The site is published by the deliverability team behind Cakemail, an email platform. It is the team that does this work daily: running sending infrastructure, responding to blocklistings and delivery incidents, and dealing with mailbox providers when mail stops arriving. What is written here is what we do.
Where we stand
We say on every page that Cakemail publishes this site, because you should know who is telling you this.
The reference is deliberately platform-neutral. It is written for senders on any platform, including platforms that compete with Cakemail, and nothing here recommends one provider over another. Our tools check any domain. Our services are sold to senders on any platform.
When we sell something, the page says what it includes and what it costs, before you talk to anyone. Nothing on this site promises inbox placement — no article, no tool, no service — because nobody honestly can.
Found a mistake?
Tell us: hi@cakemail.com. Name the page and what is wrong. We check it against the sources: when a correction holds up, we make it; when it does not, we write back and explain why. Corrections to the reference are not favours; they are how it stays worth citing.
