How EmailNa researches and reviews guides

Email changes often. Menus move, limits change and new rules arrive. Here is how we keep the guides accurate, and what we do when we get something wrong.

Official sources first

Steps and settings are checked against the provider's own help pages: Google, Microsoft, Apple, Yahoo, Proton and others. Technical rules, such as SPF, DKIM and DMARC, are checked against the published standards (the IETF RFCs) and the requirements Gmail, Yahoo and Microsoft publish for senders. The sources for each guide are listed at the bottom of the page.

Tested where possible

Where we can, we follow the steps ourselves on a real account before publishing. The free tools are tested against real domains and real addresses, and their limits are written next to them.

Dates on everything that changes

Prices, plan limits and sending limits are tied to the date the guide was last updated, shown at the top of every guide. If you're reading a price, check the provider's site before you buy.

Honest about limits

We would rather say "it depends" than promise something that isn't true. For example, no email checker can promise that a real person reads a mailbox, and no guide can promise your email will reach the inbox. When an answer has limits, we say so.

Independent, with disclosures

EmailNa is not paid by any email provider to write about it. Where a guide links to something we own, such as Veml, or includes a referral link, it is labeled on that page. See About for details.

Corrections

If a step no longer matches what you see, or a fact is wrong, please tell us. We check the report, fix the guide and update its date. We don't quietly change recommendations without updating the date.

Writing style

Short sentences, plain English, and the answer near the top. Each guide starts with a quick answer, then the steps, then the details for people who want them.
